Weather in Vinh in December

Prime time. If you get to pick your dates, December is the one. Highs average 22.7 °C, lows 16.1 °C, and rain falls on 9 days — nothing in the month is working against you.

December ranks 3 of 12 in Vinh. Only February scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 9 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. 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 December day reached 32 °C and the coldest night fell to 7.6 °C, and the wettest single day dropped 163 mm — roughly 255% of the month's rain in one day.

This is the volatile part. December rainfall has ranged from 19 mm to 342 mm across the twenty years measured — a 323 mm spread around an average of 64 mm. The average is real but almost no individual December looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 9.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 86%, high enough to notice on the warm days without dominating them.

How December sits in the year

Temperatures hold steady either side: 26 °C in November, 22.7 here, 22.7 in January. Nothing about the timing within the month matters much.

Daylight in December

December sits at the dark end of Vinh's year — 11 hours of daylight against 13.2 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 24.1 °C in December — warm enough to stay in as long as you like. The sea peaks at 29.9 °C in August and bottoms out at 21.8 °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.

December in Vinh versus nearby

If Vinh is one option among several, the nearby comparison is worth making. Thanh Hóa is close enough to be a coin toss — within a degree on temperature, 4 days less rain. Hanoi is close enough to be a coin toss — within a degree on temperature, 5 days less rain.

So: December is effectively as good as it gets here — 5 points behind February, which is inside the margin where the weather stops being the deciding factor and price starts being it.
