When to Go
The shoulder seasons - April/May and September/October - are the most pleasant times, climatically, to visit Monaco. Summer - June to August - can be very hot, and you’ll be pressing flesh with most of Europe. Winter is a better bet, as it may be a bit rainy but it’s unlikely to be too cold. Car-racing fans will probably want to be here either in January for the Monte Carlo Rally or May for the Grand Prix.
