Paris works year-round, but the trade-offs between weather, crowds, and price shift hard depending on when you go. There's no bad season here — just seasons that suit different kinds of trips.
April to June and September to October: the sweet spot
Most seasoned Paris travelers point to May and September as the two best single months, with the wider spring and early-autumn windows close behind. Temperatures sit in a comfortable 12–20°C (54–68°F) range, gardens like the Tuileries and Luxembourg are in bloom or turning gold, and crowds are noticeably thinner than summer without the grey chill of winter. September in particular sees tourist numbers drop sharply after the first week as locals return from their own holidays, while the weather often stays warm well into October.
July and August: peak crowds, and an oddly quiet second half
Summer is Paris at its busiest and most expensive, with temperatures regularly climbing past 25°C and occasional heat waves pushing higher — most hotels in the city center still lack the central air conditioning many visitors expect. August brings a strange twist: many Parisians leave the city for the month, and a real share of neighborhood bistros, bakeries, and small shops close for their own annual break, leaving a city that's simultaneously packed with tourists and missing some of its everyday local character.
November to March: cold, quiet, and the cheapest by far
Winter is Paris's low season for both crowds and prices, with January and February typically the cheapest months to visit outright. Temperatures hover in the 4–9°C range and days are short, but the trade-off is short lines at major sights and noticeably lower hotel rates. Late December is the exception — Christmas markets, illuminated shop windows, and New Year's Eve crowds push both prices and foot traffic back up for a couple of weeks.
Practical notes
- Paris has three airports — Charles de Gaulle (CDG) for most long-haul and major international routes, Orly (ORY) closer to the city center, and Beauvais (BVA) further out and used mainly by budget carriers — worth comparing all three
- Rain is spread fairly evenly across the year in short showers rather than prolonged storms, so a compact umbrella is worth packing regardless of season
- The first week of August is the peak of the closures — expect some family-run restaurants and shops to be shut, particularly outside the main tourist zones
- Book timed-entry tickets for the Louvre, Eiffel Tower summit, and similar major sights well ahead — popular slots can sell out weeks in advance in peak season
The short version
May and September give you Paris's best balance of weather and crowds. Summer is busiest and priciest, with an unusually quiet late-August lull for local life. Winter is cold but by far the cheapest and quietest, aside from the Christmas–New Year stretch.
