Your October weather guide
October is a good month for France if you prefer mild weather to summer heat and can keep plans flexible around rain. Average daytime temperatures of 18°C fall to 11°C at night, so layers matter more than beachwear. Nice is the warmer choice at 20°C by day, while Paris feels more autumnal. It suits travellers happy to spend time outdoors in a jacket, rather than those relying on hot afternoons or consistently dry skies.

Based on the averages: proper layers and a jacket - daytime highs average only 18°C; a warm layer for evenings, when it drops to around 11°C; a rain jacket - roughly 10 wet days; swimwear if you do not mind a bracing 20°C sea.
Within 1.5°C of France's October daytime average: Istanbul (19°C, sea 19°C), Thassos (19°C, sea 20°C), Pula (18°C, sea 20°C), Verona (18°C), Sunny Beach (18°C, sea 19°C). See the full ranking for October.
Nice is the better choice if warmth is your priority. Days average 20°C and nights 14°C, making it milder than Paris for both daytime outings and evenings outdoors. The sea also averages 20°C: swimming may appeal if you are comfortable with cooler water, but do not expect a warm-water holiday. Rain remains a catch, with 9 rainy days, so leave room to rearrange outdoor plans. Pack light layers alongside a waterproof jacket rather than relying on summer clothes alone. Days above 25°C account for just 1% of days, so choose Nice for gentle warmth, not the prospect of strong midday heat.
Paris suits travellers who are comfortable with cool-weather walking and switching to indoor plans when rain arrives. Its average daytime temperature is 16°C, compared with London's 15°C in October, so the difference is modest rather than a noticeable move into warm weather. Nights average 9°C, making a warmer evening layer useful even after a comfortable afternoon. With 11 rainy days, waterproof outerwear and shoes that cope with wet pavements are sensible choices. Across France, average sunshine is 4 hours a day, so bright weather should be treated as a welcome part of the trip rather than something to build every plan around.
A little more detail
Plain answers, grounded in the averages.
Nice is the warmest of the 2 places we track in France in October with an average high of 19.5°C; Paris is the coolest at 16.1°C.
Not really: the warmest sea we track in France in October is 20.2°C at Nice, below the 22°C most people find comfortable.
Nice offers the better conditions for time by the sea, with air and sea temperatures both averaging 20°C. That may suit a swim if you tolerate cooler water, but 9 rainy days and limited heat make a beach-only trip a weather-dependent choice.
Bring layers, a waterproof jacket and footwear suitable for wet days. Country averages fall from 18°C by day to 11°C at night. Pack a warmer evening layer for Paris, where nights average 9°C; Nice is milder at 14°C.
France averages 10 rainy days in October, with 9 in Nice and 11 in Paris. Neither destination is a reliably dry choice. Keep outdoor plans flexible and have indoor alternatives, rather than assuming every day will suit a long outing.
