Season by season
April-May: the boats start again and the island is quiet, but the water is still cool for swimming. A good time for the Lavezzu walk and its Sémillante cemeteries.
June: warm without being too hot, long days, still reasonable numbers. The best compromise.
July-August: the hottest and driest months (less than one rainy day in July), but also the busiest. Take the first boat and come back before the afternoon peak. Bring protection: the island has no shade (see what to bring).
September: the sea is at its warmest, the crowds leave. Rainy days pick up towards the end of the month.
October to March: no regular landings. You can see the archipelago from SPMB’s non-stop winter circuit.
The wind runs the strait
Cape Pertusato is one of the windiest places in Corsica: the wind averages 7.2 m/s (about 26 km/h) over the year, according to Météo-France, and record gusts exceed 190 km/h. The strait speeds up the wind through the Venturi effect, well known to sailors. In practice, a trip may be cancelled, shortened or switched to a sheltered cove: SPMB then offers a new date or a refund. Check the marine forecast the day before and keep a spare day in your stay.
