still close to August's peak, the sea outlasting the calendar summer
Sea temperature, bathing water and jellyfish reports: Average sea temperature
AEMET's normal for September cools only slightly from August, a 28.2°C daytime high, while rain starts to return, 20mm over 2.1 days after a dry summer. The sea barely notices the calendar turning, still 23.1°C on Open-Meteo's reanalysis, a few tenths behind August's peak. It is the one month on this page with no dated town event on the Ayuntamiento's own calendar: the summer fairs and Starlite's season are both closed out by the end of August, and the town's own film festival does not open until October. What that leaves is a quiet, still-warm month between two busier ones.
