Records and extremes, 1991-2020

The hottest day recorded in Santa Susanna between 1991 and 2020 reached 37.9°C on 12 August 2003; the coldest fell to -4.5°C on 17 December 2001. In August one day in ten tops 32.1°C and about 33% of days pass 30°C; in January one night in ten drops to 0.8°C or below. The wettest single month of the period was October 2003 with 244 mm, against a October average of 100 mm.

Winter and spring: cool evenings, gradually warmer days

December, January and February all average 13°C by day, so winter is better suited to time outdoors in layers than a beach holiday. January nights fall to 4°C; pack a warm jacket rather than relying on a jumper. March brings 16°C afternoons, but the sea remains cold at 13°C. April reaches 18°C, making daytime outings more comfortable, though evenings still need an extra layer. May is the stronger choice for warmth without summer heat, with days averaging 22°C and nights 13°C. The catch is that April and May each average 10 rain days, so keep outdoor plans flexible. Even in May, the sea averages 17°C: pleasant air temperatures do not yet mean warm swimming conditions.

Summer: the strongest choice for sunshine and swimming

June offers a useful balance: days average 26°C, nights 17°C and the sea 20°C. It suits travellers who want summer warmth but would rather avoid the hottest conditions. July brings 28°C days and 10 hours of sunshine, giving it the clearest advantage for long days outdoors; it is also the driest month. August is hotter at 29°C, with the warmest sea at 25°C, but slightly more frequent rain than July. In July and August, nights average 20°C, so light evening clothing is usually more useful than heavy layers. Plan shade breaks around midday, and do not treat any summer month as a guarantee of dry weather.

Autumn: warm seas linger as rain becomes more important

September keeps much of summer's warmth, with days averaging 25°C and the sea 24°C. It is a good fit for swimmers who can keep their plans flexible: its 11 rain days make showers a more frequent consideration than in summer. October still offers mild afternoons at 21°C and a sea averaging 20°C, but it is the wettest month overall. Bring a waterproof and a layer for evenings rather than packing only beach clothes. November marks a clearer shift away from swimming weather, with daytime temperatures of 16°C, nights of 9°C and a cooler sea. Choose it for mild daytime outings, not dependable warmth.
