Sardinia Weather September Averages, Italy

    Sardinia Weather for September 2023

    What's the weather like in Sardinia in September

    Sunshine Hours

    September is a very popular month to visit Sardinia's many beach resorts, as well the ever popular capital, Cagliari. The sun shines for a huge 8 hours per day on average, and the temperatures are a little cooler than they have been over the last couple of peak summer months; this all in all makes for the ideal time to explore the island a little more.


    You can expect an average September temperature of around 22°C in Sardinia, with a high of 26°C, and a low of only 17°C, making for some balmy summer evenings for sure. Despite that, rain is a little higher in September than it has been over the last few months, with a monthly average of around 24mm, which can affect 8 days out of the whole month. This is unlikely to be torrential, and will generally clear very quickly, as with most Mediterranean downpours at this time of year, leaving behind clear, blue skies and fresher air.

    Sea Temperature

    You can still swim and enjoy water-based fun in September, as the average sea temperature is a wonderfully warm 23°C, making September a slightly quieter, but very warm, month to visit Sardinia.

    Sardinia Hotels in September

    Blu Hotel Morisc

    Of course, Costa Smeralda is a hugely popular spot, and during September when the temperatures in Sardinia are certainly still very pleasant, a beach break here is to be recommended. Blu Hotel Morisco is located in Arzachena, close to the beaches and resort. This has a huge pool and is within a stone's throw of amenities.

    Club San Teodoro

    Alternatively, if you're visiting the beautiful beaches of San Teodoro, then Club San Teodoro is a great choice of base. This offers a half board option if you so wish, and has a complimentary buffet breakfast served daily, perfect for fuelling up for the day.

    Panorama Hotel

    If you're located in Olbia, then the Panorama Hotel offers breathtaking views over the coastline and city itself, with a roof garden for relaxing, and a spa for chilling out.

    Sardinia Beaches in September

    Cala Goloritzé

    Cala Goloritzé beach is a small slither of paradise, featuring powder white sands and stunning greenery along the cliffs; this also makes for great bird watching. The secluded nature of this beach is partly due to it being rather challenging to reach, so do bring plenty of water and supplies with you as there are no facilities here. Snorkellers will love this beach as the water is completely clear, with plenty of fish to spot.

    Cala Luna

    Golfo di Orosei is made up of many sandy beaches, one of which is Cala Luna. The beach area is lined by beautiful limestone cliffs and vibrant greenery. There are also caves to explore along the edges of the beach.

    Restaurants and Bars

    Agriturismo Li Mori

    In San Teodoro you will find Agriturismo Li Mori, a real treat for the eyes and the tastebuds. This is set in a converted Sardinian farmhouse, giving it a real rustic feel, which totally fits in with the cuisine on offer. The staff are also dressed in traditional Sardinian clothing for even more authenticity! You will find a range of Mediterranean dishes to choose from, giving you something for every taste. The handmade ravioli dishes and the pork are some of the well recommended choices here.

    La Maison

    Continuing with the rustic feel, La Maison in Sassari offers simple Italian rustic menus, set in homely surroundings, so you feel right in the heart of an Italian family meal situation! Alternatively, when in Italy you should certainly be trying some authentic pizza, and you don't get better than GiroPizza in Olbia. Try the calzones, they're huge!

    The Duke Cocktail Lounge Bar

    The Duke Cocktail Lounge Bar is perfect for those who fancy some delicious cocktails to start or end a night in Sardinia. The espresso martini here is absolutely wonderful, and a must try!

    Things to do in Sardinia in September

    La Prisgiona Nuraghe in Arzachena

    Cooler temperatures means you can explore your destination a little better, and if you're in Costa Smeralda, there is plenty to enjoy. It's not all about beaches, as there is plenty in the way of history and architecture to enjoy too. La Prisgiona Nuraghe in Arzachena offers ancient ruins to wander around and check out, with a beautiful coastline backdrop to boot.
