French Riviera in December

May through October gives you the classic Riviera experience, but each month brings trade-offs. May offers perfect weather (22°C highs) and blooming gardens, but some beach clubs haven't opened yet. June heats up (26°C) with longer days and full restaurant schedules. July and August bring peak crowds and prices. Hotel rates double, beaches pack tight, and dinner reservations require advance planning. But the energy is electric — every outdoor terrace buzzes until midnight, and the Mediterranean hits its warmest temperatures (24°C water). September might be the sweet spot. Crowds thin out, prices drop 30%, but the sea stays warm from summer heating. October extends the season with mild days (21°C) perfect for hiking the coastal paths, though some seasonal venues start closing. Winter (November-April) reveals a different Riviera. Nice's average high stays around 15°C, making it Europe's warmest major city. Most beach clubs close, but museums, markets, and restaurants keep normal hours. Hotel rates plummet — you can stay at luxury properties for half their summer prices. Avoid the Cannes Film Festival (usually mid-May) unless you're in the industry. Hotel rates spike to €500+ per night, restaurants book solid, and the city becomes a logistical nightmare for regular tourists.
