A consolidated reference for Hungnam climate: monthly averages, rebuilt from public data on a schedule. Expect -7.5 C at the coldest (Jan) and 22.0 C at the warmest (Jul) — a 29.5 C spread. Expect a wet season rather than rain year-round: Jul brings 8.06 mm/day against 0.35 mm/day in Jan. Taken together that is roughly 939 mm of rain a year for the grid cell. Because each page is rebuilt independently, one unavailable upstream never takes the rest of the site down.

What the Hungnam climate table shows
Values are multi-decadal climatological averages for the 39.84198, 127.63206 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
Why do the numbers differ from a weather app?
An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
How much rain is 8.06 mm/day in a month?
Rain is recorded as a daily mean, so 8.06 mm/day is roughly 245 mm across a 30-day month.
