Cala Bona weather by month

June, July and August are the strongest choices for warm-weather holidays in Cala Bona, with daytime averages of 25°C, 28°C and 29°C respectively. July is the driest option, while August has the warmest sea and evenings. The catch is the midday heat, so plan active time earlier or later.

Winter and spring: mild days, cool water

December brings daytime averages of 15°C, while January and February sit at 14°C. That calls for layers rather than beachwear, especially after sunset: February nights average 9°C. Each winter month averages 7 rain days, so pack a waterproof and leave outdoor plans flexible. Spring warms gradually, with March reaching 16°C, April 18°C and May 21°C. March and April suit walking without summer heat, but the sea remains cold at 14°C and 15°C. May is the better compromise if you want warmer afternoons without the hottest conditions. Its sea average of 18°C still makes swimming a cool prospect, and nights at 15°C mean a light jacket remains useful. Choose this period for comfortable outdoor time rather than reliably warm water.

Summer: the best chance of dry, warm days

June starts summer with 25°C days, 19°C nights and a sea average of 22°C, making it a good choice if July and August sound too hot. July combines 28°C afternoons with just 1 rain day on average and 12 hours of sunshine, so it offers the strongest conditions for a dry beach holiday. August is hotter at 29°C, with the sea reaching 26°C. Evenings offer less relief then, as nights average 23°C. Pack light clothing, use sun protection and keep strenuous activity away from midday. July and August suit travellers who prioritise swimming and warm evenings; June offers a little more comfort for being active.

Autumn: warm seas, but a growing rain risk

September still feels warm, with daytime averages of 26°C and sea temperatures of 25°C. The trade-off is rain: it averages 7 rain days, a clear increase from summer, so allow room to change plans. October remains a reasonable choice for swimming if you are comfortable with a sea average of 22°C, matching its daytime temperature. Nights average 18°C, making an extra layer useful later on. November is a bigger step towards cooler conditions, with 18°C days, 14°C nights and a 19°C sea. October and November both average 8 rain days. Choose early autumn for warmth in and out of the water; later autumn suits travellers happy to work around wetter weather.
