Weather in Hangzhou in June

Shoulder season. June sits in between. You will get good days and you will lose some. You should expect rain on 17 days of the month, which is more days wet than dry.

June ranks 8 of 12 in Hangzhou: past the worst of the year but short of October, which is the month to book if the dates are open.

This is wet-season rain: 17 wet days and 8 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. Pack for 30.1 °C days and 20.9 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 15 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest June day reached 37.8 °C and the coldest night fell to 13.9 °C, and the wettest single day dropped 84 mm — roughly 37% of the month's rain in one day.

June is moderately variable: 48 mm in the driest year against 463 mm in the wettest, around an average of 230 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind is light at 7.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 80%, high enough to notice on the warm days without dominating them.

How June sits in the year

The month is on the way up: 2.7 °C warmer than May, and July adds another 2.8 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in June

June is at or near the longest days of Hangzhou's year: 14.1 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

With no coast nearby, the year swings a fair way — 33.1 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

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.

June in Hangzhou versus nearby

If Hangzhou is one option among several, the nearby comparison is worth making. Shanghai is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Nanjing is close enough to be a coin toss — within a degree on temperature, 5 days less rain.

So: June is a compromise. October is 35 points better and is what Hangzhou is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
