The best time to visit Bath is June, July and August, when average highs are at their most comfortable — July reaches 21.1 °C and August 20.6 °C, each with 12 rain days, and July enjoys 11 hours of sunshine a day. July and August fall in peak season, coinciding with the school holidays that fill the city and its Roman Baths. The quiet, low season runs through winter, when January highs sit at 7.3 °C with just 3.9 hours of sunshine — cheaper and calmer, but chilly and short on daylight.

How the months are picked.A month qualifies when its average high sits in the comfortable 20–28 °C band (scored down towards 9 °C and 37 °C), rain days are few and sunshine hours are high — at least 78 % of the city's best-scoring month. July and August are then set aside as peak season (school-holiday crowds and prices) whenever at least three other months qualify; where summer is the only comfortable window they stay. Figures are ten-year averages (2016-01-01 to 2025-12-31) from ERA5 reanalysis data via Open-Meteo (CC BY 4.0) for the city centre coordinates.
When to go, and what to expect
Spring (Mar–May)
A pleasant, greener alternative for those who want warmth without peak crowds.
Summer (Jun–Aug)
The best all-round time to visit; go in June for the same warmth with slightly fewer people.
Autumn (Sep–Nov)
September still feels mild and calmer; later autumn turns grey and wet.
Winter (Dec–Feb)
Worth it for the festive market and steaming Roman Baths, if you don't mind the cold.
