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
