A ‘nice temperature’ for UK travellers typically falls between 18°C and 24°C – warm enough for shorts and a T-shirt, but not so hot that you feel uncomfortable. This range is common in late spring (May) and early autumn (September), though April can offer pleasant, cooler days around 13–16°C.
What counts as a nice temperature?
It depends on what you’re doing. For a day out in the park, 20–22°C feels ideal. For hiking or sightseeing, 16–20°C is often more comfortable, especially if you’re moving around. The Met Office considers 18–24°C as ‘comfortable’ for most outdoor activities, with humidity and wind playing a role.
When can you expect nice temperatures in the UK?
May and June are the most reliable months for consistently nice conditions, with average highs of 17–21°C in southern England. September also delivers good weather, often warmer than May. For a nice temperature in April, expect 12–16°C – pleasant but pack a jumper. Nice temperature in February is rare; the UK averages 7–9°C, so you’ll need layers.
