The best time to visit Monaco is late spring (May and June) and September, when the Mediterranean weather is warm and pleasant, the sea is swimmable, and the crowds thin out compared to the July–August peak. Summer is hot and extremely busy, while winter is cool, quiet, and much calmer. Note that late May brings the Formula 1 Grand Prix, which is thrilling but sends prices and crowds soaring, so plan around it depending on your interests.
