Your Guide to Alicante [By an Alicantinian]
Alicante’s weather is surprisingly good all year round. Winters are -generally- dry, sunny and warm, including December as it is not an exception.
In December, Alicante enjoys warm weather with an average temperature of 12.55°C, peaking at 17.7°C. Days offer about 9.5 hours of light with no rain. Sea temperatures average 16.7°C, attracting some tourists for swimming. The city celebrates a vibrant festive season with various Christmas events.
Alicante is still vivid in winter. Christmas and New Year’s are very festive in Spain and Alicante is not an exception. Good weather, Christmas markets, events and the general festive vibe make Alicante a good city to be in during December.
The average temperature in December is 12.55°C (54.59°F). When the Sun is shining in the sky the average temperature gets to 17.7°C (63.86°F). At night it gets a bit colder averaging 7.4°C (45.32°F). Winters in Alicante are warm!
The average direct sun irradiation in December is 5.3h. But counting all sunshine hours you will enjoy 10.5 hours of light. To give some context, a city like Oslo, Norway, has around 6 hours of sun irradiation, almost half that of Alicante.
The sea temperature during December averages 16.7°C (62.06°F). Only January, February, March and April average colder temperatures than December.
The local people won’t go swimming in December in Alicante. During good December days, only some brave tourists will enjoy the water as it is cold for the general public.
The beaches are open all year round and, on the sunnier and warmer days, people enjoy Alicante’s beaches such as El Postiguet or San Juan.
I wouldn’t say you can swim in Alicante in December. It might be just warm enough for a quick swim but not for staying in the water for a long time without a wet suit. In fact, 16°C inside the water feels actually way cooler than just outdoors as your body loses heat much faster in water.
The average of precipitations is low in Alicante in December. We have left behind September, October and November which are the three wetter months of the year. The average of rainy days in December is 3.7 days.
In the city of Alicante, it never snows. To be accurate, no one remembers it. There are some images of snow in 1932. That year was the last time it snowed and settled for a few hours. Never again since then.
If you want to find snow you can drive a few kilometres up in the mountain. Almost every year the snow will settle there for a couple of days or so, depending on the year.
As you can see, December might not be a month for going to the beach but is warmer than in many other cities in Spain and Europe. It is perfect for escaping the cold and dark winter.
December is one of the coldest months of the year in Alicante. Days get the shortest all year round as the winter solstice is on the 21st/22nd of December.
Nevertheless, Alicante in December is fun and vivid.
If you are a tourist, the main activities remain open:
In 2023, the Christmas lights and decorations are inaugurated on Friday 16 of November.
Some of the special decorations are the Christmas tree in Avenda de la Cosntitucion, a gigantic Bear in Plaza de la Montaneta and the Christmas lights in 114 streets around Alicante. The lighting will be turned on from 7 pm to 1 am. On Christmas Eve, New Year’s Eve and Three Wise Men Eve -the night of the 5th to the 6th of January- the lights will be turned on until 4:30 am.
