Weather in Thanh Hóa in July

A hard month. July is a hard month in Thanh Hóa, and worth planning around. You should expect rain on 20 days of the month, which is more days wet than dry.

July ranks 12 of 12 — near the bottom of Thanh Hóa's year. February is the month that works, and the swing between the two is 55 points, which is a different holiday rather than a slightly better one.

Rain on 20 of the month's 31 days, 8 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 83% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 28 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest July day reached 41.1 °C and the coldest night fell to 23.9 °C, and the wettest single day dropped 116 mm — roughly 48% of the month's rain in one day.

July is moderately variable: 82 mm in the driest year against 607 mm in the wettest, around an average of 243 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 6.7 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 July sits in the year

Temperatures hold steady either side: 32.9 °C in June, 32.6 here, 31.6 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Thanh Hóa's year: 13.2 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 29.8 °C in July — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

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.

July 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, 3 days less rain. Hanoi is close enough to be a coin toss — within a degree on temperature, 3 days more rain.

So: July is a compromise. February is 55 points better and is what Thanh Hóa is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
