Weather in Lille in October

A good month. October works. It is not the peak, but nothing about it fights you. Highs average 15.9 °C, lows 7.6 °C, and rain falls on 13 days — nothing in the month is working against you.

October ranks 7 of 12 in Lille: past the worst of the year but short of June, which is the month to book if the dates are open.

Rain on 13 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 15.9 °C days and 7.6 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest October day reached 26.1 °C and the coldest night fell to -3.8 °C, and the wettest single day dropped 26 mm — roughly 40% 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 127 mm against 33 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 65 mm average is a reasonable planning figure, not a promise.

Wind is light at 11.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 86%, high enough to notice on the warm days without dominating them.

How October sits in the year

The month is on the way down: 4.3 °C cooler than September, with November dropping another 5.4 °C. The first week and the last are not the same trip.

Daylight in October

10.8 hours of daylight, losing 1.9 hours across the month. That is between Lille's extremes of 16.4 and 8 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 22.6 °C between the year's warmest afternoons and coldest nights.

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 Lille versus nearby

If Lille is one option among several, the nearby comparison is worth making. Breda is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Rotterdam is close enough to be a coin toss — within a degree on temperature, 2 days more rain.

So: October works, with June the better month by 16 points if the dates can move. If they cannot, nothing here should stop you booking.
