The Best Time To Visit London
To help visitors determine the most suitable time for their trip, we have developed two travel scores: the tourism score and the beach/pool score.
The tourism score favors clear, rainless days with comfortable temperatures between 65°F and 80°F. Based on this score, the most favorable period for general outdoor tourist activities is from late June to early September, with the peak score falling in the third week of July.
The beach/pool score prioritizes clear, rainless days with warmer temperatures between 75°F and 90°F. According to this score, the best time to visit London for hot-weather activities is from mid-July to mid-August, with the peak score occurring in the last week of July.
These scores are calculated based on factors such as perceived temperature, cloud cover, and total precipitation. Each hour between 8:00 AM and 9:00 PM for every day within the analysis period (1980 to 2016) is independently scored, and these scores are then combined into a single hourly composite score. This composite score is further aggregated into days, averaged over all years within the analysis period, and smoothed to provide a clear representation of the optimal time to visit for various activities.
These scores, combined with the visual representations of London’s weather, provide a comprehensive guide for planning your trip to this vibrant city.
