Records and extremes, 1991-2020

The hottest day recorded in Benidorm between 1991 and 2020 reached 40.9°C on 4 July 1994; the coldest fell to -1.4°C on 28 January 2005. In August one day in ten tops 33.8°C and about 65% of days pass 30°C; in January one night in ten drops to 4.6°C or below. The wettest single month of the period was October 2007 with 192 mm, against a October average of 48 mm.

Winter and spring: mild days, cool evenings

January is the coolest month, with days around 15°C and nights at 8°C, so bring a jacket rather than relying on holiday T-shirts. December and February both reach 16°C by day, but evenings still call for layers. March lifts daytime temperatures to 18°C, making time outdoors more comfortable without much heat. April reaches 20°C, though its 7 rain days mean a light waterproof remains useful. May is the stronger choice for warmth, with days at 23°C and nights at 15°C. The catch is the sea: it averages just 18°C in May and is colder earlier in spring. These months suit travellers who prefer walking and sitting outside to spending long stretches in the water. Choose later spring if you want lighter clothing during the day.

Summer: the strongest choice for sun and swimming

June combines 28°C days with 11 hours of sunshine and just 2 rain days, making it a good fit for a holiday spent mostly outdoors. July is drier still, averaging 1 rain day, with daytime temperatures of 30°C and sea temperatures of 25°C. August is the hottest month, with days around 31°C and the sea at 26°C. That warmth is useful for swimming, but midday is less comfortable for being active. Plan more energetic outings for the morning and leave room for shade later. Nights average 22°C in July and August, so do not expect evenings to feel particularly cool.

Autumn: warm water first, more layers later

September is the best autumn option if swimming matters: the sea stays at 25°C while days average 27°C. The compromise is rain, with 6 rain days compared with the much drier early summer. October still offers 23°C days and a 22°C sea, so it can suit travellers who dislike peak summer heat. It is also the wettest month, making flexible outdoor plans sensible rather than assuming every day will be dry. By November, days average 19°C and nights fall to 12°C. There is still scope for comfortable time outdoors, but pack layers and treat swimming as a cool-water choice rather than the main reason to travel.
