Most answers to this question are really answers to a different one: when is Paris cheapest, or when is the weather warmest. Neither is the question a lot of visitors are actually asking. If the constraint on your trip is availability rather than budget — the table you want, the suite you want, the museum without the school groups — the calendar looks quite different.
The short version: late April to early June, and September to mid-October. What follows is why, and what to know about every other month.
| Period | Weather | Crowds | Rates | Verdict |
|---|---|---|---|---|
| January – February | Cold, grey, short days | Lowest | Lowest | Best value; the museums to yourself |
| March | Mild, wet, lengthening | Rising | Moderate | Improving, still quiet |
| Late April – early June | Mild, long evenings | Busy but not peak | High | The best of the year |
| July | Warm to hot | Peak | High | Long evenings; full city |
| August | Warm to hot | Peak visitors, no locals | Softening | Half the neighbourhood closed |
| September – mid-October | Mild, clear | Busy, civilised | High | The other best of the year |
| Late Oct – November | Turning cold, dark | Falling | Falling | Underrated; good value |
| December | Cold, festive | Rising to peak | Peak over the holidays | Illuminations; book far ahead |
Late April to early June. The city has come out of winter, the terraces are open, the light lasts into the evening, and everything is running. The parks and the gardens at Versailles are at their best in May. It is busy, but it is not July.
September to mid-October. Parisians are back from holiday, so the restaurants are open and the city has its own life again. The weather often holds clear and mild well into October, the summer crowds have thinned, and the cultural season restarts — new exhibitions, the opera, the theatres. If we had to pick one fortnight in the year, it would be the second half of September.
Both windows share the thing that actually matters: the city is fully open and not yet full. That combination does not exist in July, and it does not exist in February.
August is the month visitors are warned about, usually for the wrong reason.
The heat is not the problem. The problem is that August is when Parisians take their holidays, and a significant share of the smaller restaurants, bakeries, cheesemongers and independent shops simply close for two or three weeks. Some post a handwritten note in the window; some do not. The neighbourhood you chose for its life may be shuttered for the fortnight you are there.
What stays open: the major museums, the monuments, the department stores, the hotels and their restaurants, and anything that lives on visitors. What closes: a good deal of what makes a district feel like itself.
The city is therefore at its emptiest of residents and its fullest of tourists at the same time. If your trip is built around the sights, August works. If it is built around eating well in a particular quarter, check that your restaurants are open before you commit — and expect to book the ones that are.
One genuine upside: the traffic. Paris in the first three weeks of August drives like a different city.
These do not appear on tourist calendars, and they are the ones most likely to disrupt a carefully planned trip.
Paris hosts several fashion weeks across the year — womenswear, menswear and haute couture, at different points from January to October. During them, hotel rates in the 1st, 8th and 16th arrondissements can double, the best tables are held for the industry, and private cars become genuinely scarce, booked out weeks ahead by houses and their guests.
If your travel is flexible and you have no reason to be there, check the dates and move around them. If you are coming for it, book everything — hotel, restaurants, car — considerably earlier than feels necessary.
The exhibition centres at Porte de Versailles and Paris Nord Villepinte host events that bring tens of thousands of business travellers into the city at once. Hotel rates across whole districts move for the week, often with no visible reason to a leisure visitor wondering why a familiar hotel has tripled.
The vacances scolaires fall in several waves through the year and they do two things: they fill the family attractions, Disneyland Paris especially, and they load the motorways out of the city on the departure and return weekends. If a day trip is planned for one of those Saturdays, expect the road to take noticeably longer.
This is our own trade, so it is worth being specific. A handful of days each year shut major axes across Paris entirely, and no car — taxi, private hire or otherwise — can work around them.
None of these is a reason to change your trip. All of them are a reason to say so when you book transport, so the day is built around them rather than into them. If you are travelling to or from an airport on one of these dates, leave earlier than you would otherwise — see our guide to getting between CDG and Paris.
Paris is temperate and changeable rather than extreme. Winters are cold and grey but rarely severe; the difficulty is the daylight, which is gone by around five. Summers are warm and occasionally very hot, and the older buildings — including some very good hotels — were not built for it, so confirm air conditioning if you are coming in July or August.
Rain is possible in every month, including the ones people think of as dry. The practical conclusion is that no month requires you to plan around the weather, and every month requires a coat that copes with it.
One thing that does change materially: the length of the evening. In June the light lasts past ten and the city stays outdoors. In December it does not. That difference shapes a trip far more than the temperature does.
Before you arrive: every way from CDG into Paris and tipping, which is smaller than you expect. Planning a day with commentary: guide or driver, and which you actually need. On the way home: the VAT refund on your shopping. Day trips: Mont-Saint-Michel, Giverny and Monet’s garden, a day in Champagne. Eating well while here: the starred restaurants and how their tables are released. Flying private: arriving at Le Bourget by private jet.
Event dates move from year to year. Where a specific week matters to your plans, confirm it against the organiser before booking.
