Weather Score #

Heat Seeker Score is a composite score designed for those who crave hot, sunny weather with minimal rainfall. It prioritizes high temperatures and abundant sunshine.

Perfect for sun worshippers, beach lovers, and those seeking warm, dry climates for outdoor activities and relaxation.

Formula optimized for hot weather enthusiasts who prefer temperatures above 25°C (77°F) with maximum sun exposure and minimal precipitation.

Key factors in the calculation:

High temperatures: Favors locations with warm to hot daily highs
Abundant sunshine: Rewards areas with maximum daylight hours
Low precipitation: Penalizes frequent rain and wet conditions
Warm nights: Considers comfortable evening temperatures

London experiences cool temperatures throughout the year, with comfortable temperatures only in June, July, August and September.
Several months, including January, February, and December, have minimum temperatures that fall into the discomfort range.
The peak temperatures occur in July and August, while the lowest are in January and December.
