Hay-on-wye's weather is influenced by its location in western Wales, near the Brecon Beacons mountains. Mountains block and redirect winds, causing changes in air pressure. This leads to unpredictable weather, with sudden rain or shine.
The town's valley location traps and compresses air, making air pressure lower than in surrounding hills. This compression warms the air, making Hay-on-wye slightly drier than surrounding areas.
In winter, air pressure is generally lower, bringing more rainfall and wind. Spring and autumn have more stable pressure, making the weather calmer. Summer's higher pressure leads to drier, sunnier days.
Hay-on-wye has a mild oceanic climate, characterized by mild winters and cool summers. This climate type means air pressure is generally milder, with fewer extreme pressure changes. However, its mountainous surroundings still lead to local pressure changes and varied weather.
