What’s the weather like in Sardinia in September?
Located in the Tyrrhenian Sea, Sardinia’s the second largest island in the Mediterranean after Sicily. Sitting off Italy’s west coast and the north of Africa, you can enjoy the end of the long and hot summer in September, which has high temperatures, lots of sun and not much rain.
Sardinia’s quite hilly, which means there’s differences in weather around the island. The south’s a bit drier than the north, while the wetlands that surround the capital Cagliari in the south east are milder and more humid. North of there’s a region of flat, dry plains with more extreme temperatures. Closer to the mountains the weather’s cooler and wetter, while breezes will keep you cool on the coast. Sardinia’s known for being in the path of several winds such as the Sahara Desert’s hot sirocco wind and the mistral wind from the Alps.
The average high reaches 26ºC in September, which has pleasant evenings that cool to 17ºC. The sea temperature’s 23ºC, while humidity’s low. Average rainfall’s 24mm over eight rainy days, and you can expect there to be eight hours of sunshine from the 12 hours of daylight each day. UV levels will be high so bring sun cream. Sunset’s just before 8pm at the start of September; this is closer to 7pm by the end of the month.
Things to Do
The September weather’s great for you to head to the beach in Sardinia as the summer crowds get thinner. There’s lots of bays and coves to explore, with over 80 coves along the north coast alone. Sardinia has really lush scenery, although it might be too hot to do much hiking, golfing or climbing. Diving, snorkelling and windsurfing could be better options.
