June is high for Monaco.
June is hot, sunny, and busy — around 25°C/18°C with the sea now a swimmable 21°C and Monaco's longest days. It's the start of the summer season.
The defining event is the Monaco Grand Prix, which in 2026 runs June 5-7 (it moved from its long-standing late-May date). During race weekend Monaco is overwhelmed: roads close, grandstands fill the casino square, the Oceanographic Museum shuts, and hotel prices across the Riviera multiply — book a year or more ahead if you're attending, or deliberately avoid that weekend if you're not.

Monaco in June — Full Picture
June is hot, sunny, and busy — around 25°C/18°C with the sea now a swimmable 21°C and Monaco's longest days. It's the start of the summer season.
The defining event is the Monaco Grand Prix, which in 2026 runs June 5-7 (it moved from its long-standing late-May date). During race weekend Monaco is overwhelmed: roads close, grandstands fill the casino square, the Oceanographic Museum shuts, and hotel prices across the Riviera multiply — book a year or more ahead if you're attending, or deliberately avoid that weekend if you're not.
Outside the Grand Prix, June is excellent — warm enough for Larvotto and the beaches, sunny for sightseeing, and not yet at August's peak heat or crowds. Mornings and early evenings are best for walking the old town and circuit.
Note: confirm the exact Grand Prix dates for your travel year, as they affect everything from prices to which sights are open.
What to Wear & What to Pack
Warm early summer — around 25°C/18°C, sunny and dry. Summer clothing, swimwear, sunglasses, and SPF 50. Evenings stay pleasant. Bring smart wear if you'll enter the casino.
