Monaco and the French Riviera are set for a largely sunny and increasingly hot start to September, with daytime temperatures climbing well above seasonal norms by the end of the week. The forecast points to highs building steadily over the coming days across the Principality, reaching the high 20’s by midweek and peaking close to 30°C early next week under near-unbroken sunshine.
Clear skies and light winds are expected to hold across the coast for much of the first week of the month. Highs should reach the high 20’s from midweek, with around 28°C on Wednesday rising to 29°C from Thursday and holding through the weekend. By early next week the mercury could touch 30°C in Monaco before easing slightly. Overnight lows will stay mild throughout, generally between 19°C and 22°C, keeping evenings warm along the coast.
Well above the seasonal average
The spell will run several degrees warmer than is usual for the time of year. Average daytime highs along this stretch of coast sit at around 24 to 25°C in early September, easing as the month goes on, which places forecast highs of 29 to 30°C some four to six degrees above the norm.
Sea temperatures also remain warm after the summer – around 24°C – and will continue to hover around this temperature over the next few days before minor fluctuations later in the week.
A change expected from mid-month
The uninterrupted sunshine, however, may not last. Some forecasts point to a shift from around the second week of the month, with the chance of rain and cooler, more autumnal conditions arriving from about 10th September. Highs would then ease into the mid-to-high 20’s and nights turn noticeably cooler, dropping towards the mid-teens later in the month.
But for now, warm and largely cloud-free conditions are set to see in the new month across Monaco and the wider French Riviera.
