Being a UNESCO title world heritage site, Bath was once a Roman Spa Town and has since become a charming retreat with ultra-modern spas in addition to the ancient ones. As is true for the rest of South West England, Bath too has a moderate weather, which gets milder and wetter compared to the rest of the country, with the average mean temperature at 10°C. Given that the city is completely surrounded by a green belt, which extends into much of its neighboring districts and more, Bath contributes a fair deal in preventing urbanization any further or unplanned expansions more toward Bristol or Bradford-on-Avon, in addition to shielding the smaller villages en route.

The best time to visit Bath is early June through the end of September. The average temperatures vary rarely, and given the humidity levels, temperatures tend to feel cold for about 6 months in the year while the other half is rather pleasant with an occasional chance of rain or snowfall. The warmest part of the year to visit Bath is July, August and then June. Tourism is at its peak in August, July & September in Bath, hence chance of finding budgeted accommodation or flight deals during this period would be next to none.

Spring is moderately cold with the combined levels of temperatures and humidity, with the average high varying between 18°C and 9°C. With rains common with 5-6 days in a month, spring slows down tourism a great deal in Bath, giving way to lucrative travel deals for visitors looking for budgeted stays and flights.

June through August experience cool weather with high temperatures, which is still comfortable and witnesses 7-9 days of rainfall each month. This makes summer the busiest time of the year to visit Bath, making lodging and accommodation fairly expensive.

The average high temperature during fall ranges between 20°C-9°C, giving off a chilly feel to the weather and witnessing at least 4-11 days of rain or snowfall every month. This makes September through November the second busiest time of the year to visit Bath.

December through February is really cold and most inappropriate for warm weather enthusiasts, with the average high ranging between 9°C-7°C and an average rainfall of 7-11 days every month, slowing tourism further down. You cannot even visit the baths here or enjoy their tranquility with such freeing cold. So winters are best avoided.
