Horse Blanketing Temperature Chart: When to Blanket Your Horse

Horse Blanketing Temperature Chart: When to Blanket (And When Not To)

Blanketing is one of those horse-care topics where two smart, experienced people can disagree—and both can be “right” depending on the horse in front of them. A good horse blanketing temperature chart isn’t a single magic number. It’s a starting point that you adjust based on coat, body condition, wind, rain, turnout, and whether your horse is clipped.

This guide gives you a practical chart, then teaches you how to use it like a pro: quick checks, real-life scenarios, breed examples, common mistakes, and product picks that actually match conditions.

The Horse Blanketing Temperature Chart (Quick Reference)

Use this chart as a baseline for a healthy adult horse at maintenance (not very old, not sick, normal weight), with 24/7 access to hay and water, and adequate shelter. Then adjust using the factors in later sections.

Baseline Chart (By Temperature + Weather)

Legend

• •No blanket = naked is fine
• •Sheet = 0g (uninsulated, wind/rain barrier)
• •Light = ~100–150g fill
• •Medium = ~200–250g fill
• •Heavy = ~300–400g fill

A) Horse with a full winter coat (not clipped)

• •Above 50°F (10°C): No blanket (most horses)
• •40–50°F (4–10°C):
• •Dry, low wind: No blanket
• •Rain/wet snow or windy: Sheet
• •30–40°F (-1–4°C):
• •Dry, low wind: No blanket or Sheet if thin-coated
• •Wet/windy: Light
• •20–30°F (-7–-1°C):
• •Dry: Sheet or Light (depends on body condition)
• •Wet/windy: Medium
• •10–20°F (-12–-7°C):
• •Dry: Light (most), Medium for harder keepers
• •Wet/windy: Medium to Heavy
• •Below 10°F (-12°C):
• •Dry: Medium (most), Heavy for seniors/thin horses
• •Wet/windy: Heavy, consider layering

B) Horse clipped (trace/blanket/body clip)

• •Above 60°F (16°C): Usually no blanket; a sheet if cool rain/wind
• •50–60°F (10–16°C): Sheet (especially with wind/rain)
• •40–50°F (4–10°C): Light
• •30–40°F (-1–4°C): Medium
• •20–30°F (-7–-1°C): Heavy (or Medium + liner)
• •Below 20°F (-7°C): Heavy + liner; watch skin warmth and sweating

Pro-tip: Think in terms of the horse’s lower critical temperature (LCT)—the point where they must burn extra calories to stay warm. A healthy adult with a good coat can have an LCT around the 30s°F, but wind and wet conditions can push that “effective” temperature way lower.

Step 1: Decide What “Temperature” Actually Means (Ambient vs. Wind Chill vs. Wet)

A chart is only useful if you use the right inputs. Two 40°F days can feel totally different to a horse.

Wind changes everything

Wind flattens the hair coat, which is the horse’s natural insulation system. A fluffy winter coat works like a puffy jacket—until wind collapses it.

• •Light wind (5–10 mph): often bumps you “one blanket level”
• •Strong wind (15+ mph): can bump “one to two levels,” especially in open turnout

Wet is colder than cold

Rain + wind can chill a horse faster than a dry, colder day because water conducts heat away from the body.

Use a simple rule:

• •If your horse will be wet for more than ~30–60 minutes, consider a waterproof turnout even if the temp seems mild.

Sun and shelter are real factors

A sunny 35°F day with a run-in shed and hay can be more comfortable than a gray, damp 45°F day with no windbreak.

Step 2: Know Your Horse’s “Blanket Profile” (Breed, Coat, Age, Weight)

This is where the blanket chart becomes personal.

Breed examples: who runs hot vs. cold?

• •Thoroughbred (often thin skin/coat): tends to need earlier blanketing at the same temp vs. a stocky breed.
• •Arabian: can vary—many do fine unblanketed if acclimated, but some are leaner and may appreciate a sheet in wet wind.
• •Quarter Horse: many grow a solid winter coat and do well with minimal blanketing unless clipped or older.
• •Morgan: typically hearty with good coats; often less blanket needed.
• •Warmblood: frequently comfortable, but body condition and management matter—some are big hay burners and stay warm, others are sensitive.
• •Drafts (e.g., Percheron, Belgian): usually run warm; blanketing can lead to overheating, especially if heavy-bodied and well-coated.
• •Miniature horses: higher surface-area-to-volume ratio, can chill faster; they may need blanketing sooner, especially if thin or older.

Seniors, hard keepers, and metabolic concerns

• •Senior horses may have less efficient thermoregulation; arthritis can worsen when cold and damp. They often benefit from earlier blanketing in wet/cold conditions.
• •Hard keepers burn calories to stay warm; blanketing can save weight by reducing heat loss.
• •Easy keepers (and horses with a history of laminitis/EMS): be careful—blanketing can reduce calorie burn and contribute to weight gain.

Body condition matters (use the hand test)

A horse with a BCS 4/9 (a little thin) will need more help than a BCS 6/9 (moderate fleshy). Fat is insulation. So is muscle.

Step 3: The Hands-On Check That Beats Any Chart

If you learn only one skill, make it this: check the horse’s temperature under the blanket and at key body zones.

Where to feel

Slide your hand under the blanket at:

• •Behind the elbow (great indicator)
• •Base of neck/shoulder
• •Flank

What you want

• •Warm, dry skin = good
• •Cool skin + horse acting tucked/uncomfortable = likely under-blanketed
• •Hot or sweaty = over-blanketed (a bigger problem than many owners realize)

Behavior clues

Signs your horse may be cold:

• •Shivering
• •Tail clamped, tucked posture
• •Standing hunched with back tight
• •Seeking shelter constantly (when they usually don’t)
• •Eating less or acting tense

Signs your horse may be too warm:

• •Sweaty shoulder patches
• •Damp neck/chest
• •Restless, rubbing blanket
• •Mild dehydration risk if sweating and not drinking well

Pro-tip: A horse can feel “warm” under a heavy blanket but still be uncomfortable if they’re sweating and then getting chilled. Sweat + cold air later = a recipe for chills, skin funk, and rubs.

Blanket Types (And What They’re Actually For)

Choosing the right type prevents the classic mistake of throwing a heavy on at the first cold snap.

Sheets (0g)

Best for:

• •Windy days
• •Cool rain
• •Horses that run warm but need a barrier

Avoid when:

• •It’s genuinely cold and the horse needs insulation

Light turnout (100–150g)

Best for:

• •Mild cold, wet wind
• •Thin-coated breeds (TBs)
• •Transitional weather

Medium turnout (200–250g)

Best for:

• •Consistent cold
• •Seniors/hard keepers
• •Most “real winter” days in many climates

Heavy turnout (300–400g)

Best for:

• •Very cold climates
• •Clipped horses in deep winter
• •Seniors or thin horses during extreme cold snaps

Stable blankets vs. turnout blankets

• •Stable blanket: not waterproof; higher breathability; for dry indoor use
• •Turnout blanket: waterproof and durable; for outside

If a blanket will see turnout, choose turnout, period.

Liners: the underrated best practice

A liner system lets you adjust warmth without swapping bulky outer shells:

• •Outer waterproof turnout (0g shell) + liners (100g, 200g)
• •Easier washing (liners wash easier than full turnouts)
• •Less rubbing if fitted well

Real-Life Scenarios (How to Apply the Chart)

Scenario 1: Unclipped Quarter Horse, 38°F and raining, 10–15 mph wind

Even though 38°F sounds “not that cold,” wet + wind is the issue.

• •Good call: Waterproof sheet or light turnout (if horse is lean)
• •Watch for: horse standing miserable and not using shelter

Scenario 2: Thoroughbred, thin coat, 45°F dry but windy, full turnout

TBs often chill faster.

• •Good call: Sheet
• •If horse is BCS 4/9 or older: consider light

Scenario 3: Body-clipped Warmblood in training, 52°F and cloudy

Clipped horses lose their built-in insulation.

• •Good call: Sheet if windy, otherwise no blanket during the day
• •Overnight at 45°F: likely light

Scenario 4: Draft with a huge coat, 25°F dry, access to hay and run-in

This horse is likely fine without a blanket.

• •Good call: No blanket
• •Risk of blanketing: sweating, skin funk, rubs

Scenario 5: Senior Morgan, 32°F and damp, stiff in the mornings

Even if the horse “can tolerate” it, comfort matters.

• •Good call: Light or medium depending on wind and body condition
• •Bonus: may improve willingness to move and loosen up

Step-by-Step: How to Choose the Right Blanket Today

Use this quick decision workflow.

1) Start with your baseline chart category

• •Full coat vs. clipped

2) Adjust for weather “penalties”

Add warmth if any apply:

• •Wet (rain/wet snow): +1 level (or at least waterproof shell)
• •Windy (15+ mph): +1 level
• •No shelter / open field: +1 level in cold/windy weather

3) Adjust for your horse “penalties”

Add warmth if any apply:

• •Senior (roughly 20+)
• •Underweight / hard keeper
• •Thin-coated breed (often TB)
• •Recent move to colder climate (not acclimated)
• •Limited forage availability (hay is internal heat!)

4) Do the under-blanket check later

Recheck in 30–60 minutes after a change, then again at night if temps drop.

5) Recheck at the temperature swing points

Most blanketing problems happen during:

• •Warm afternoons after cold mornings
• •Rapid cold fronts
• •Sunny days that feel warmer than the forecast

Product Recommendations (Practical Picks + What to Look For)

Blanket choice is about fit, waterproofing, breathability, and hardware quality. You don’t need the most expensive blanket—but you do need one that stays put and stays dry.

Features worth paying for

• •1200D+ outer for turnout durability (especially with playful turnout mates)
• •True waterproof + breathable fabric
• •Shoulder gussets for freedom of movement
• •Wither relief design to reduce rubs
• •Leg straps that adjust securely (not dangling)
• •Replaceable liners if you like modular systems

Reliable brands (commonly well-reviewed in barns)

• •Horseware Ireland (Rambo/Rhino/Amigo): excellent liner ecosystem, strong waterproofing
• •Bucas: known for breathable, performance-oriented designs
• •Schneiders / Kensington: good options depending on model; Kensington is popular for durable fabrics
• •WeatherBeeta: broad price range, solid mid-tier options
• •SmartPak house blankets: often good value with decent fit options

Simple “starter set” that covers most winters

If you want a minimal but flexible kit:

1. Waterproof turnout sheet (0g)
2. Light turnout (100–150g)
3. Medium turnout (200–250g) or a liner system (100g + 200g)

For a clipped horse in a cold climate:

• •Waterproof turnout + heavy option (300–400g) or turnout + 200g liner + 100g liner stacked (if compatible)

Comparison: One heavy vs. layering

• •One heavy: simpler, fewer pieces, but easy to overheat during swings
• •Layering: more adjustable, easier to fine-tune, but requires good fit and compatible systems

Common Blanketing Mistakes (And How to Avoid Them)

1) Over-blanketing “just in case”

This is the #1 issue I see. Overheating causes:

• •Sweat chills later
• •Skin irritation and fungus
• •Dehydration risk
• •Blanket rubs and hair loss
• •Reduced natural coat function over time

If you’re unsure, pick the lighter option and do a recheck.

2) Ignoring wet conditions

A soaked coat plus wind can chill even a hearty horse. A waterproof shell can be more important than added grams.

3) Poor fit = rubs, pressure, and restricted movement

Common red flags:

• •Tight chest buckles pulling backward
• •Wither pressure or bald spots
• •Shoulder rubs
• •Blanket sliding to one side

Make sure you can fit a hand comfortably at the chest and withers, and the blanket sits centered.

4) Leaving the same blanket on for days without checking

Even “set it and forget it” horses need checks:

• •Blanket shifts
• •Straps loosen
• •Weather changes
• •Weight changes mid-winter

5) Blanketing without enough forage

Hay is the horse’s internal furnace. In cold snaps, the best “blanket” can be more hay (as appropriate for the horse’s health).

Expert Tips for Special Situations

Clipped horses: manage sweat and cooldown

If you clip, plan your blanketing like a system:

• •Use coolers after work until fully dry
• •Don’t trap sweat under heavy blankets
• •Consider multiple weights to match training days vs. rest days

Pro-tip: If your clipped horse is warm under a medium blanket but comes in with damp shoulders, drop a level and add a windproof sheet if needed. Dry warmth beats sweaty warmth.

Horses that live out 24/7

Prioritize:

• •Waterproofing
• •Neck coverage if windy and wet (optional, depends on fit)
• •Durable denier
• •Daily strap checks

Rain rot and skin fungus prevention

Blankets can create a humid microclimate. Reduce risk by:

• •Using breathable turnouts
• •Ensuring the horse is dry before blanketing
• •Washing/airing blankets regularly
• •Checking shoulders, withers, and back for heat and moisture

Minis and ponies

They can be tough—but they’re also closer to the ground, get wetter, and can chill fast when thin.

• •Use the chart, but pay extra attention to wet + wind
• •Avoid over-blanketing easy keepers (weight gain risk)

Horses with arthritis

Cold and damp often worsen stiffness.

• •A light or medium during cold/wet periods can improve comfort
• •Make sure the blanket doesn’t restrict shoulder movement (gussets help)

Your “No-Regrets” Daily Blanketing Routine

If you want an easy system that prevents most problems, do this:

Morning (2 minutes)

1. Check forecast: temp range, wind, precipitation
2. Decide blanket using chart + adjustments
3. Quick strap check and centering

Afternoon (2 minutes)

1. Feel under the blanket at elbow/shoulder
2. Adjust one level if hot/sweaty or cool/tucked

Evening (2 minutes)

1. Re-check if temps drop overnight
2. Confirm waterproof blanket if rain/wet snow is coming

This routine is how barns keep horses comfortable without turning blanketing into drama.

Quick FAQ: Blanket Decisions You’ll Face All Winter

“If my horse has a winter coat, should I ever blanket?”

Yes—especially in wet wind, for seniors, hard keepers, and thin-coated breeds. But many healthy, well-fed horses with shelter do great unblanketed in dry cold.

“Is shivering always an emergency?”

Not always. Brief shivering can happen during a sudden weather change. But persistent shivering means your horse is cold enough to be burning energy hard—add warmth (blanket, shelter) and ensure hay/water access.

“Can I blanket a wet horse?”

Try not to. Putting insulation over wet hair traps moisture. If you must protect from wind/rain, use a breathable waterproof sheet and check frequently, or bring the horse in to dry first.

“Do neck covers matter?”

They can in wet, windy weather or for clipped horses. But poor fit can cause rubs and restrict movement, so only use one that fits correctly and doesn’t pull.

The Bottom Line: How to Use a Horse Blanketing Temperature Chart Correctly

A horse blanketing temperature chart is a smart baseline—not a rulebook. Start with temperature, then adjust for wet, wind, shelter, coat, clip status, age, and body condition. Your best tool is your hand under the blanket and your horse’s behavior.

If you tell me:

• •your horse’s breed, age, body condition (easy keeper or hard keeper),
• •clipped or not,
• •your typical winter temps and whether turnout is sheltered,

I can suggest a tailored “blanket schedule” (day vs. night) with the minimum number of blankets to buy.
