Horse Care in Hot UK Weather: Essential Summer Tips

While the British summer is often unpredictable, recent years have shown that prolonged periods of hot weather and heatwaves are becoming increasingly common. To help keep horses comfortable, healthy and safe during warmer weather, a few simple management adjustments can make a significant difference to their wellbeing.

Whether you own a retired pony, competition horse or manage a busy livery yard, preparing for periods of hot weather can help reduce the risks associated with rising temperatures and ensure your horses remain comfortable throughout the summer months.

Ensure Constant Access to Fresh Water

Hydration is one of the most important factors in managing horses during hot weather. A typical 500kg horse may drink between 50 and 70 litres of water per day in warm conditions, and even more when exercising or travelling.

Check water troughs regularly throughout the day to ensure they remain clean, cool and topped up. Some horses can become reluctant to drink when away from home, so monitoring individual drinking habits is always worthwhile.

You may also wish to provide multiple water sources where horses share turnout, feed soaked feeds or soaked hay where appropriate, and consider using electrolytes during periods of prolonged heat or increased exercise.

Provide Adequate Shade and Shelter

Whether horses are stabled or turned out, access to shelter is essential.

Field shelters provide reliable protection from direct sunlight and biting insects, while mature trees and hedgerows can offer valuable natural shade. During periods of particularly hot weather, many owners choose to alter turnout routines by turning horses out overnight and bringing them in during the hottest part of the day.

If stabling during daylight hours, ensure stables remain well ventilated and avoid creating excessively hot or enclosed environments. These simple measures can help reduce heat stress and improve overall comfort during periods of extreme weather.

Adapt Exercise and Riding Schedules

Even fit horses can struggle in high temperatures and humidity.

During particularly hot periods, consider riding early in the morning or later in the evening, reducing the intensity and duration of exercise, and incorporating more frequent breaks where necessary. Choosing shaded hacking routes and monitoring recovery times carefully after work can also help reduce the effects of heat.

Remember that humidity can significantly reduce a horse’s ability to cool itself through sweating, meaning that even moderate temperatures can become challenging.

After exercise, one of the most effective cooling methods is to continuously apply cold water over the horse’s body, allowing the water to evaporate naturally rather than immediately scraping it away.

Be Vigilant for Signs of Heat Stress

Recognising the early signs of heat-related illness is crucial.

Watch for signs such as:

✔ Excessive sweating or, conversely, reduced sweating
✔ Rapid breathing
✔ Elevated heart rate
✔ Lethargy or depression
✔ Dark urine
✔ Dry gums or tacky saliva
✔ Weakness or poor recovery after exercise

If you suspect your horse is suffering from heat stress or heat exhaustion, move them to a shaded area immediately, begin active cooling with cold water and contact your veterinary surgeon if symptoms persist.

Manage Flies and Insects Effectively

Hot weather often brings an increase in flies and biting insects, which can add further stress and discomfort for horses.

Using breathable fly rugs and masks, applying suitable fly repellents and adjusting turnout times can all help minimise irritation. However, one of the most effective long-term strategies remains maintaining excellent paddock hygiene.

Regular removal of droppings helps minimise breeding sites for flies while also contributing to improved pasture management and parasite control.

Pay Attention to Summer Grazing Conditions

Dry weather can quickly alter the nutritional profile of grazing. Grass that appears sparse or sunburnt may still provide substantial calories while offering reduced nutritional value.

Horse owners should monitor body condition regularly and be prepared to adjust forage and supplementary feeding where necessary. Equally, following rainfall after prolonged dry periods, grass growth can increase rapidly, creating additional risks for horses prone to laminitis.

Regular paddock maintenance and rotational grazing can help maintain healthier pasture throughout the summer season.

Don’t Forget Paddock Hygiene

Hot weather creates ideal conditions for increased fly activity and accelerated parasite development on pasture. Keeping paddocks clean during summer is therefore about much more than appearance alone.

Frequent dung removal helps reduce fly populations, supports effective parasite management programmes and creates a healthier grazing environment. During prolonged periods of warm weather, maintaining paddock hygiene becomes even more important.

For owners managing multiple horses or larger acreage, dedicated paddock cleaning systems can make maintaining high standards of paddock hygiene considerably easier during the busiest months of the year.

Prepare for the Season Ahead

Taking the time to adjust your horse management routine during periods of hot weather helps ensure your horses remain comfortable, healthy and able to cope with the challenges of increasingly warm UK summers. Good management not only improves welfare but can also help prevent more serious health issues developing during periods of prolonged heat.

A well-managed paddock and a well-cared-for horse are key to a healthier, safer and more enjoyable summer season.
