Monte Carlo in June

May through June gives you perfect weather without the summer madness. Temperatures hit 24°C, the Mediterranean is swimmable, and hotel rates haven't peaked yet. September and October offer the same sweet spot—warm days, fewer crowds, and that golden Mediterranean light photographers love. Avoid July and August unless you enjoy paying €1,200 per night to share the sidewalk with cruise ship passengers. Winter (December-March) sees many restaurants and attractions close, but if you're here for the casino action, you'll find better hotel deals and actual parking spaces. The Monaco Grand Prix in late May turns the city into chaos—book a year ahead or stay away entirely.
