This summer has brought weather at both extremes. Alongside heavy rain, long hot spells and warm nights have made the grazing season difficult for many horses. Strong sunshine, horseflies, midges and flies can make horses restless and increase stress.
In hot weather, the priorities are constant access to clean water, shade and sufficient rest. Many horses prefer to stay in a stable or shelter during the hottest part of the day and graze when the evening becomes cooler.
Heat places a greater strain on horses than many people realise
Horses regulate body temperature by sweating, but prolonged heat increases the strain on the body. Take particular care with older horses, foals, and horses in intensive work or competition.
Adequate water intake is the single most important factor. A horse may drink considerably more than usual in warm weather, so check and refill clean water containers several times a day. Sweating can also increase the need for minerals and electrolytes.
Horses at pasture should always be able to seek shade. Natural tree cover or a well-ventilated shelter reduces exposure to sun and heat. On a completely open pasture, consider bringing the horse indoors during the hottest hours and turning it out again later in the evening.
Horseflies and midges take the pleasure out of grazing
For many horses, insects rather than high temperatures are the greatest challenge in summer and early autumn. Horseflies, flies and midges can make grazing unsettled and create continuous stress.
A horse uses considerable energy trying to repel insects. Tail swishing, head shaking and constant movement reduce opportunities to eat and rest calmly. Some horses become restless or nervous, while others stand close to companions or seek windy locations.
Sensitive horses can develop strong skin reactions or sweet itch. A well-fitting fly mask protects the eyes and ears, and a fly rug can reduce irritation when needed. Repellents may provide relief when horseflies are abundant. Clean pastures and stable surroundings also matter: regular manure removal reduces breeding opportunities for flies.
Three effective insect-repellent options
Pine-tar grease. A traditional option even for sensitive areas. The strong smell of genuine kiln-burned pine tar repels many insects, while added fats or oils care for the skin.
Effol Fly Blocker Gel. The gel is particularly suitable for horses that dislike sprays and provides long-lasting protection against horseflies, flies and midges.
Dr. Repel. A Finnish-made repellent whose active ingredients include pine-tar oil and tea-tree oil.
Rest remains essential during the grazing season
Even when a horse spends most of the day outdoors, it still needs a calm place to rest. A well-bedded stall allows the horse to relax without constant disturbance from insects. A clean, dry surface supports hoof and skin health and makes lying down more comfortable.
Bedding has to work harder in summer. Heat increases evaporation and can intensify ammonia formation, making good absorbency and moisture retention particularly important.
Biohansa peat and wood-shaving bedding combines the moisture-binding performance of peat with the soft structure of shavings. The blend helps keep the stall drier and binds ammonia, improving stable air quality.
A soft, dry bed encourages the horse to rest lying down, while a clean stall makes daily work easier. Every summer is different: sometimes rain is the main challenge, sometimes heat and insects. Daily observation and adapting management to the weather can prevent many problems.
