Weather in Busan in February
South Korea · 20-year averages, February
A hard month. February asks something of you. Go in knowing what. Highs sit at 8.4 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.
February ranks 10 of 12 — near the bottom of Busan's year. October is the month that works, and the swing between the two is 42 points, which is a different holiday rather than a slightly better one.
Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. Layers, and a genuinely waterproof outer — at 8.4 °C the difference between a good day and a miserable one is entirely down to what you are wearing.
What the averages hide
Averages flatten a month, and this one hides a few things: 10 nights fall below freezing. Across the twenty years measured, the hottest February day reached 18 °C and the coldest night fell to -10.8 °C, and the wettest single day dropped 46 mm — roughly 88% of the month's rain in one day.
February is moderately variable: 7 mm in the driest year against 105 mm in the wettest, around an average of 52 mm. Roughly two Februarys in three land near that average, and the third does something else entirely.
Wind is light at 14.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 72%.
How February sits in the year
The month is on the way up: 2.3 °C warmer than January, and March adds another 3.9 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.
Daylight in February
10.9 hours of daylight, gaining 1 hours across the month. That is between Busan's extremes of 14.5 and 9.8 hours, so days are long enough not to constrain the plan.
Sea temperature
The sea sits at about 13.9 °C in February — too cold to swim without a wetsuit. The sea peaks at 26.9 °C in August and bottoms out at 13.9 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.
How busy it gets
Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
February in Busan versus nearby
If Busan is one option among several, the nearby comparison is worth making. Daegu is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Gwangju is close enough to be a coin toss — within a degree on temperature, the same number of rain days.
So: February is a compromise. October is 41 points better and is what Busan is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
