מזג האוויר במונקו באוגוסט

Regulars name August their least favourite month on this coast and the reasons are all human: French holidays empty the cities onto the shore, so the restaurants, the transport and the traffic all strain, and the prices follow. Their temperature range of 27 to 29C is our row's 28.9C, with extremes recorded near 38C and late August capable of feeling miserable - they advise booking air conditioning. Against that air they call the Mediterranean surprisingly cool, which is a contrast rather than a figure: ours reads 26C. Their recommendation is September, which they say holds the same air and water with a fraction of the crowd. The record: 22.6C nights, 37.5mm across 7.3 days and 12.5 hours of sun.

Monaco-forum threads on January weather describe a cold but frequently sunny month, coats and layers the norm but posters consistently reporting genuinely beautiful blue-sky days mixed in among the cooler, greyer ones. Regulars call it a fine time to visit for anyone chasing the views rather than the beach, the Rock and the harbor both photographing just as well under a crisp winter sky. Compared to the rest of northern Europe in the same month, posters describe the Riviera's winter as noticeably gentler, cold enough for a proper coat but rarely miserable for a walk along the port. Restaurants and the main sights stay open through the month, though the famously packed summer crowds are entirely absent, a real plus for anyone wanting to see the casino district without a crush of people. The record: 13.2C days feeling like 11C, 6.2C nights, 53mm across 6.8 days, a 14.9C sea, 75 percent humidity and 7 hours of sun.

Monaco-forum threads on June are short on drama compared to the Grand Prix month that precedes it - one poster's blunt summary is that it 'will be quite hot in June so take sun block, a hat, and comfortable shoes', and by this point the harbour and casino district are back to a normal, walkable pace. It's the start of real beach weather too, with the Mediterranean warming into swimmable territory. June's record: 25.1C days feeling like 29C, 19.5C nights, 13.2 hours of sun and a 23C sea - humid enough at 78 percent that the feels-like number does real work, with 9.8 rainy days still in the mix before the driest stretch of summer arrives.

Monaco forum regulars call March genuinely changeable: “some days sunny and warm, others rainy, sometimes there's a cold wind,” with the mood of a visit depending heavily on when Easter falls that year. It's quiet by Riviera standards — fewer crowds than the summer season — and every main attraction stays open, though regulars suggest checking specific opening times before counting on anything. A sunny day is called out as ideal for photographs, with the Rock and the harbor at their least crowded. Our record: 15°C days, 7.6°C nights, 5.2 rain days and a 13.9°C sea — mild and mostly dry on average, with the day-to-day swing the forum describes sitting underneath that number.

Monaco forum regulars call November a gamble rather than a write-off: “weather in November is impossible to predict with any certainty” — “if you are lucky it will be sunny and around 15C in the afternoon,” but “unlucky” means “10C and/or raining heavily,” since October and November are “the 2 rainiest months of the year.” Layer for both outcomes: a jacket for morning and evening is standard, but it can feel warm if the sun's out. One visitor who caught a clear stretch reported eating outside the whole stay. Our record: 15.8°C days, 10.1°C nights, 10.8 rain days and an 18.3°C sea still swimmable if the sun holds — consistent with the coin-flip framing.
