What is Horsham’s typical climate through the year?
Horsham has a temperate maritime climate, like most of south-east England. Winters are cool and damp, with daytime highs usually in single figures and occasional frost. Summers are mild to warm, with temperatures often reaching the low 20s Celsius. Rainfall is spread fairly evenly across the year, though autumn and winter tend to be the wettest. The area is not particularly windy compared to coastal parts of Sussex.
Does the local geography affect Horsham’s weather?
Horsham sits in the Weald, a wooded area of low hills and valleys. This means it can be a little cooler and cloudier than nearby coastal towns such as Worthing. The North and South Downs shelter the town from some stronger winds, but fog can form in the valleys on still autumn and winter mornings.
When is the best time to visit Horsham, and what should I pack?
Late spring and early summer (May to July) offer the best balance of mild weather and longer daylight hours. Pack layers and a waterproof jacket in any season. In winter, bring a warm coat and sturdy shoes for wet ground. A sun hat and sunscreen are useful in the summer months.
