Weather in Thanh Hóa in February
Vietnam · 20-year averages, February
Prime time. If you get to pick your dates, February is the one. Highs average 24.3 °C, lows 15.4 °C, and rain falls on 5 days — nothing in the month is working against you.
February is the highest-scoring month of the twelve. The nearest rival is January, and the month at the other end of the year is July.
Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest February day reached 36.1 °C and the coldest night fell to 5.7 °C, and the wettest single day dropped 36 mm — roughly 200% of the month's rain in one day.
February is moderately variable: 5 mm in the driest year against 44 mm in the wettest, around an average of 18 mm. Roughly two Februarys in three land near that average, and the third does something else entirely.
Wind is light at 8.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.
How February sits in the year
The month is on the way up: 2.8 °C warmer than January, and March adds another 3 °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
February sits at the dark end of Thanh Hóa's year — 11.5 hours of daylight against 13.3 at midsummer, gaining 0.5 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.
Sea temperature
The sea sits at about 21 °C in February — comfortable for a proper swim. The sea peaks at 30 °C in August and bottoms out at 21 °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
Peak season. Expect the highest prices of the year and to be booking well ahead.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
February in Thanh Hóa versus nearby
If Thanh Hóa is one option among several, the nearby comparison is worth making. Vinh is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Hanoi is close enough to be a coin toss — within a degree on temperature, 1 day more rain.
So: February is the answer for Thanh Hóa. If it is booked out or priced out, January is the next best thing at 1 points behind, and July is the month to keep off the shortlist.
