Weather in Le Havre in August

Prime time. August is about as good as Le Havre gets. Highs average 20.7 °C, lows 15.7 °C, and rain falls on 12 days — nothing in the month is working against you.

August ranks 2 of 12 in Le Havre. Only July scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 12 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 August reaches 30 °C; the day barely swings — 4.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest August day reached 33.4 °C and the coldest night fell to 12.4 °C.

August is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest August on record still delivered 113 mm against 21 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 64 mm average is a reasonable planning figure, not a promise.

Wind is light at 13.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 81%, high enough to notice on the warm days without dominating them.

How August sits in the year

Temperatures hold steady either side: 20.3 °C in July, 20.7 here, 19 in September. Nothing about the timing within the month matters much.

Daylight in August

14.5 hours of daylight, losing 1.6 hours across the month. That is between Le Havre's extremes of 16.3 and 8.2 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 17.2 °C in August — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. This is the warmest the water gets all year.

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.

August 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 — 4.2 °C warmer, 1 day less rain. London is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: August is effectively as good as it gets here — 2 points behind July, which is inside the margin where the weather stops being the deciding factor and price starts being it.
