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 #

Pyongyang and Sariwon have the widest temperature ranges, with comfortable temperatures between June and September.
Ch'ongjin experiences the coolest summers with July and August highs around 24°C, while other cities reach closer to 27-29°C.
Most cities experience discomfort temperatures in January and December.
Wonsan and Nampo have relatively milder winters compared to other locations.
Coastal cities such as Wonsan and Nampo tend to have milder temperature variations overall.

Daylight Hours #

Overall, the cities in North Korea exhibit similar patterns in sunrise, sunset, and day length variations throughout the year. June consistently shows the earliest sunrises and latest sunsets across all cities, with Ch'ongjin having the longest day at 15 hours and 10 minutes.
In contrast, December presents the shortest days, with significant variations in day length; Ch'ongjin has the shortest day at 9 hours and 12 minutes while Tanch'on shows a slightly lengthier day at 9 hours and 20 minutes. The consistent trends indicate that cities closer to the North Korean coast, like Ch'ongjin and Hamhung, may experience earlier sunrises and later sunsets compared to inland cities like Sariwon and Pyongyang.
