Weather in Le Havre in June

A good month. June works. It is not the peak, but nothing about it fights you. Highs average 18.3 °C, lows 13 °C, and rain falls on 11 days — nothing in the month is working against you.

June ranks 4 of 12 in Le Havre: past the worst of the year but short of July, which is the month to book if the dates are open.

Rain on 11 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

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average June reaches 30 °C; the day barely swings — 5.3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 28.7 °C and the coldest night fell to 8.5 °C, and the wettest single day dropped 27 mm — roughly 53% of the month's rain in one day.

June is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest June on record still delivered 105 mm against 17 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 51 mm average is a reasonable planning figure, not a promise.

Wind is light at 13.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, high enough to notice on the warm days without dominating them.

How June sits in the year

The month is on the way up: 2.9 °C warmer than May, and July adds another 2 °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 Le Havre's year: 16.3 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 13.5 °C in June — too cold to swim without a wetsuit. The sea peaks at 17.4 °C in September and bottoms out at 8.6 °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.

June in Le Havre versus nearby

If Le Havre is one option among several, the nearby comparison is worth making. Paris is close enough to be a coin toss — 4.5 °C warmer, the same number of rain days. London is close enough to be a coin toss — 2.2 °C warmer, the same number of rain days.

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