Namp’o has a monsoon-influenced hot-summer humid continental climate.
Hot, humid summers. Genuinely cold winters with snow. Rain in every month — here's what that means in plain terms.
What this climate feels like
The four things a regular visitor actually wants to know:
Highs near 29°C in August.
Lows near −8°C in January.
About 719 mm of rain a year. Wettest in July.
A roughly even mix of sun and cloud.
What "monsoon-influenced hot-summer humid continental" means
Climate scientists sort every place on Earth into about 30 climate types, based on how hot, cold, wet and dry it is across the year. Namp’o's type — monsoon-influenced hot-summer humid continental — sits in the broad family of four-season continental climates.
Researchers write climate types as a short letter code. Here is what each letter means:
Cities with the same climate as Namp’o
A monsoon-influenced hot-summer humid continental climate (Dwa) — these recognizable cities share it. If you know one of them, you know roughly what to expect.
Namp’o sits near a climate boundary
This city sits right on the line between monsoon-influenced hot-summer humid continental and the next type along. Different climate maps file it on different sides of that line; the lived weather doesn't change at the line — it's a naming boundary, not a wall.
Has Namp’o's climate type changed?
Stable — Namp’o's climate has held the same type between the 1971–2000 and 1991–2020 normals. The label is steady; the climate beneath it is still warming.
What this climate means for you
Rice, corn, soy and apples on the monsoon. Winter shuts the garden down.
Spring and autumn are the comfortable windows; summer is hot and stormy, winter is cold and dry.
Cold dry winters with biting wind, hot humid summers. A sharp two-season feel.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from Namp’o's measured 30-year climate normals (1991–2020) — the same official records behind Namp’o's main climate page, so the two always agree.
Long-range climate maps measure things slightly differently and can place a city in a neighbouring category. Where they differ, this page uses the measured station record as the climate today.
Methodology & sources
Temperature & precipitation — 1991–2020 normals computed from 30 years of daily observations at Nampo, a weather station, about 3 km from the city centre. The underlying daily records come from NOAA's global station network.
