Weather in Le Havre in October

Shoulder season. October is shoulder season in Le Havre — cheaper, quieter, and a genuine gamble. You should expect rain on 16 days of the month, which is more days wet than dry.

October ranks 7 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.

This is persistent light rain rather than storms: 16 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Pack for 16 °C days and 11.7 °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: the day barely swings — 4.4 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest October day reached 25.2 °C and the coldest night fell to 4 °C, and the wettest single day dropped 28 mm — roughly 33% of the month's rain in one day.

October is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest October on record still delivered 182 mm against 35 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 85 mm average is a reasonable planning figure, not a promise.

Wind sits around 17.6 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 84%, high enough to notice on the warm days without dominating them.

How October sits in the year

The month is on the way down: 3 °C cooler than September, with November dropping another 4 °C. The first week and the last are not the same trip. Rain has already shifted: 6 days more than September had.

Daylight in October

10.9 hours of daylight, losing 1.8 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 16.2 °C in October — 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

Shoulder. The value months — prices ease off and you get the place closer to itself.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

October in Le Havre versus nearby

If Le Havre is one option among several, the nearby comparison is worth making. Paris is a better bet in October — within a degree on temperature, 4 days less rain. London is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: October is a compromise. July is 22 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.
