Yearly weather

Calculations are based on the last 8 years of historical weather data.

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

Temperatures #

Trujillo, Lima, Callao, and Chiclayo maintain generally comfortable temperatures throughout the year.
Iquitos and Piura experience discomfort temperatures, especially during the hotter months, with temperatures often exceeding 30°C.
Arequipa, Cusco, Huancayo and Machu Picchu have cooler temperatures, sometimes dropping into the discomfort zone, particularly during the months of May to August. Machu Picchu is the coldest location in this comparison.

Maximum/minimum temperature averages are computed by averaging the max/min temperature of each day for a given period.

Conditions #

Arequipa, Trujillo, and Piura generally experience higher sun hours, especially during the months of May through October, while also having minimal precipitation during those times
In contrast, Cusco, Machu Picchu, Huancayo, and Iquitos have significantly lower sun hours throughout the year and higher precipitation levels, especially from January to March and again in November and December
Coastal cities like Lima and Callao show moderate sun hours and very low precipitation, with a slightly discernible increase in sun hours from March to October
Overall, there's an apparent inverse relationship between sun hours and precipitation across these Peruvian locations, with inland and highland regions tending to be cloudier and wetter than coastal and desert areas.
