Why is my horse’s coat matted and stuck together in wet weather?

Overview
If your horse’s coat is matted and stuck together in wet weather, the most common reason is that the coat has been staying damp for too long. Rain scald is one possible cause, but mud, sweat, heavy feather, grooming residue, or underlying skin irritation can also make the coat clump together.
It’s worth checking the skin underneath carefully. If there’s redness, scabs, broken skin, heat, swelling or discomfort, that gives you a better clue about what’s going on.
Things To Check
1. See whether the coat sticks together after rain, turnout, washing, exercise, or a full day in a wet field.
2. Part the coat and look closely at the skin underneath for scabs, flakes, redness, damp patches or small crusts.
3. Check whether the horse seems sore, itchy, or unhappy when you touch or groom the area.
4. Look at the weather exposure, especially whether the horse has been left wet for long periods or is not drying properly.
5. Make sure tack, rugs, and grooming kit aren’t trapping moisture or leaving residue on the coat.
6. Check whether the problem is only in one area, such as the back, quarters, mane, or lower legs, or whether it’s spread across the coat.
7. Note whether there’s a smell, discharge, or any skin damage that looks more than simple damp coat clumping.
Common Causes
Rain scald is a common cause, especially when the coat stays wet and the skin starts to become irritated. It often shows as small crusts or scabs with tufty, matted hair.
Wet mud, sweat, or poor drying after washing or exercise can also make the coat stick together without it being a skin condition.
Less commonly, skin sensitivity, rubbing from rugs or tack, or another skin problem may be involved if the area keeps recurring or looks inflamed.
What To Do
Gently part the coat and keep an eye on the skin so you can tell whether it’s just dampness or something more active. Try to dry the horse thoroughly after rain or washing, and avoid rubbing the area hard if the skin looks sore.
If the horse is out in wet weather, check whether a change in turnout, rugging, or shelter access could help reduce how long the coat stays damp. Keep grooming tools clean and avoid using anything that leaves the coat oily or sticky unless it’s part of your normal care routine.
If the coat is repeatedly matting in the same place, make a note of when it happens and what the skin looks like each time. That makes it much easier to spot a pattern and decide whether the problem is simply weather-related or needs a closer look.
