Weather in Fukuoka in July

A hard month. July is a hard month in Fukuoka, and worth planning around. You should expect rain on 18 days of the month, which is more days wet than dry.

July ranks 11 of 12 — near the bottom of Fukuoka'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.

This is wet-season rain: 18 wet days and 9 genuinely heavy ones, which in this climate means concentrated downpours rather than all-day grey. The pattern is usually a clear morning and a loud afternoon, so front-load the day and stop fighting the 3pm hour. Natural fibres and a second shirt for the day. At 85% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 20 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest July day reached 38.8 °C and the coldest night fell to 17.6 °C, and the wettest single day dropped 175 mm — roughly 49% of the month's rain in one day.

July is moderately variable: 72 mm in the driest year against 773 mm in the wettest, around an average of 357 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 3.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 85% is the real story though — it is the number that decides how the day feels, not the 31.1 °C.

How July sits in the year

Temperatures hold steady either side: 27.8 °C in June, 31.1 here, 32.1 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Fukuoka's year: 14.2 hours of daylight, losing 0.5 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 24.4 °C in July — warm enough to stay in as long as you like. This is the warmest the water gets all year.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

July in Fukuoka versus nearby

If Fukuoka is one option among several, the nearby comparison is worth making. Kitakyushu is a better bet in July — 3.3 °C cooler, the same number of rain days. Hiroshima is close enough to be a coin toss — within a degree on temperature, 3 days less rain.

So: July is a compromise. October is 39 points better and is what Fukuoka is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
