The short answer
If you want the Riviera at its best, come between late April and mid-June, or from September to mid-October. The sea is warm enough to swim from June, the light is extraordinary, the villages are open and alive, and you can still find a table on a terrace without a reservation made weeks ahead. I guide all year, and those are the weeks when my guests come back from a day in Eze or Saint-Paul-de-Vence saying it was easier and more beautiful than they expected.
Spring: April to June
April is fresh, sometimes showery, and almost empty. The gardens of Cap-Ferrat and Menton are in full bloom and the Old Town of Nice belongs to the locals again. May brings the two events that fill every hotel on the coast: the Cannes Film Festival and the Monaco Grand Prix. Both are fascinating to see from the outside, but if neither is your reason for coming, avoid their dates: roads close, prices double and Monaco becomes a building site of grandstands for weeks. June is, for me, the finest month of the year. Long evenings, warm sea, and the summer crowds not yet arrived.
Summer: July and August
Summer is glorious and demanding. Temperatures sit above 30 degrees, the hilltop villages are busy from mid-morning, and the coast road to Monaco can take twice its normal time. It is still a wonderful time to come if you plan around the heat: villages early, sea or shade at midday, towns again in the evening. This is exactly how I build summer days, starting Eze at nine when the lanes are still cool and nearly empty. Book restaurants and experiences well ahead; August is when the whole of France is on holiday here too.
Autumn: September and October
September is my other favourite. The sea is at its warmest of the year, families have gone home, the light turns golden and the markets overflow with figs and the last tomatoes. October stays mild, often above 20 degrees, with the occasional dramatic storm that clears the air for a week of perfect blue. Cruise traffic in Villefranche is at its heaviest in these two months, so I keep my shore excursions moving against the flow of the tenders.
Winter: November to March
The Riviera does not close in winter, it exhales. Days are short but often sunny, around 12 to 15 degrees at noon, and you will have the Prince's Palace square or the ramparts of Saint-Paul almost to yourself. Some village restaurants shorten their hours, and a few gardens close, so the itinerary needs more care. February is the surprise of the calendar: the Nice Carnival, the Lemon Festival in Menton and the mimosa in bloom on the hills behind Cannes. For a quiet, cultural, well-priced visit, winter is underrated.
How I would decide
Choose late May or June if you want sea, villages and energy without the August crush. Choose September or early October for the warmest water and the softest light. Choose February if you love festivals and empty museums. Whatever the month, the day itself matters more than the season: starting early, choosing the right village for the right hour and knowing which road is open is where a private guide earns his keep. That is the part I take care of.

Frequently asked
What is the rainiest month on the French Riviera?
October and November see the most rain, usually in short, intense episodes followed by clear days. Even then, a storm rarely lasts a full day, and I adapt the itinerary toward museums, covered markets and villas.
Can you swim in the sea in May or October?
In May the water is around 18 degrees, fine for the brave. From mid-June to early October it is comfortably warm, and late September is often the best swimming of the year.
Which dates should I avoid in Nice and Monaco?
The Monaco Grand Prix in late May and the Cannes Film Festival in mid-May, unless they are your reason for coming. Also the first fortnight of August, when French holidays peak and the coast road is at its slowest.
