The live forecast above shows today’s conditions in Brentford. West London’s weather is typically mild and damp, with the best months being May–September for warmer, drier spells and longer daylight hours for exploring the riverside.
When is the best time to visit Brentford?
Late spring to early autumn (May to September) gives you the most reliable warmth, with average highs of 20–24°C. July and August are often busiest, especially near the Brentford Lock and Kew Bridge area. For fewer crowds and still pleasant conditions, June or September work well. Pack layers even in summer, as evenings can cool quickly, and a waterproof is wise any month. School holidays fall in late July to early September, so book accommodation early if travelling then.
What should you pack for Brentford weather?
Brentford’s climate is temperate, so a light jacket or fleece is useful most of the year. In winter (December–February), bring a warm coat, hat and gloves; average lows hover around 3°C. A compact umbrella is always a good idea—rain can arrive abruptly. For summer, light fabrics and sunscreen are fine, but a mid-layer helps for evenings. If you’re visiting the Griffin Park area or walking along the Grand Union Canal, comfortable waterproof footwear is a smart choice.
