How Does Weather & Best Time Work in UK?
Last verified: 2025-06 · Europe
1The Quick Answer
June to August offers the warmest weather and longest days; rain is possible in any month so always carry a waterproof layer.
2What You Need to Know
The UK has a temperate maritime climate with mild temperatures year-round and famously changeable weather. Summer (June–August) is the warmest period with London averaging 18–22°C and the most daylight hours. Spring (April–May) brings fresh greenery and lower crowds. Autumn (September–October) offers dramatic colours and fewer tourists. Winter (December–February) is cold, grey, and wet but Christmas markets and festive events are popular. Rain can occur in any month — a compact waterproof jacket is essential at all times of year. Bank Holidays and UK school holiday weeks bring significant crowds and higher accommodation prices.
