Weather in Le Havre in July

Prime time. If you get to pick your dates, July is the one. Highs average 20.3 °C, lows 15.1 °C, and rain falls on 11 days — nothing in the month is working against you.

July is the highest-scoring month of the twelve. The nearest rival is August, and the month at the other end of the year is January.

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 July reaches 30 °C; the day barely swings — 5.1 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 32.1 °C and the coldest night fell to 11.3 °C, and the wettest single day dropped 40 mm — roughly 73% of the month's rain in one day.

July is moderately variable: 19 mm in the driest year against 157 mm in the wettest, around an average of 55 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 13.7 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 July sits in the year

Temperatures hold steady either side: 18.3 °C in June, 20.3 here, 20.7 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Le Havre's year: 15.9 hours of daylight, losing 0.9 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 15.7 °C in July — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. 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.

July 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 — 4.7 °C warmer, the same number of rain days. London is close enough to be a coin toss — 2.5 °C warmer, 2 days more rain.

So: July is the answer for Le Havre. If it is booked out or priced out, August is the next best thing at 2 points behind, and January is the month to keep off the shortlist.
