Weather in Le Havre in December

France · 20-year averages, December

A hard month. December is a hard month in Le Havre, and worth planning around. Highs sit at 8.9 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

December ranks 11 of 12 — near the bottom of Le Havre's year. July is the month that works, and the swing between the two is 48 points, which is a different holiday rather than a slightly better one.

Rain on 16 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 8.9 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 3.4 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest December day reached 14.3 °C and the coldest night fell to -1.9 °C, and the wettest single day dropped 31 mm — roughly 32% of the month's rain in one day.

December is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest December on record still delivered 181 mm against 23 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 97 mm average is a reasonable planning figure, not a promise.

Wind sits around 20.1 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 88%, which at 8.9 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How December sits in the year

Temperatures hold steady either side: 12 °C in November, 8.9 here, 8 in January. Nothing about the timing within the month matters much.

Daylight in December

December sits at the dark end of Le Havre's year — 8.2 hours of daylight against 16.3 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 11.8 °C in December — 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

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.

December 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 — 2 °C cooler, 3 days less rain. London is close enough to be a coin toss — within a degree on temperature, 3 days less rain.

So: December is a compromise. July is 46 points better and is what Le Havre is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
