Along the Costa de Almería, the portion of the Spanish southern coast in the province of Almería, the climate can be considered as Mediterranean, in fact, is has mild, relatively rainy winters and hot, sunny summers. However, the aridity is remarkable, so much so that the landscape is desert. There are several beaches that are located in a rocky and arid environment.
Geographically, the Costa de Almería is divided in the western part (called Poniente Almeriense, where there are towns like Adra, El Ejido, Berja, Roquetas de Mar, Almerimar, Enix, and the nature reserve of Punta Entinas-Sabinar), the central part (where we find the Bay of Almería with the capital city, in addition to the Cabo de Gata and Nijar), and the eastern part (Levante Almeriense, where we can find the towns of Carboneras, Mojacar, Garrucha, Vera, Pulpí, Cuevas del Almanzora, and Villaricos). In the east, a short distance from Carboneras, there is a small island, called Isla de San Andrés.
In the central part, we find the Cabo de Gata-Nijar Natural Park. In the interior, north-west of Almería, we find the Tabernas Desert.
There are many sunny days, with daytime temperatures reaching or exceeding 20 °C (68 °F), even in winter. In winter, very cold days are rare, but on colder periods, the minimum temperature can drop to about 0 °C (32 °F); in practice, it never snows. In summer, the heat is generally bearable, and sea breezes blow, but there may be periods of intense heat, during which temperatures can even reach 38/40 °C (100/104 °F).
Here are the average temperatures in Almería.

The rains in the Costa Almería are decidedly scarce, since they are usually lower than 300 millimeters (12 inches) per year, and follow the Mediterranean pattern, in fact, most of them fall from October to April, while in summer, it almost never rains. Not surprisingly, the landscape is often desert even on the coast. In Almería, in the wettest month, December, only 30 mm (1.2 in) of rain fall. In the Cabo de Gata area, precipitation drops below 200 mm (8 in) per year.
This is the average rainfall in Almería.

There are on average six hours of sunshine per day even in December and January. Here are the average sunshine hours per day.

Best Time

The best time for a beach holiday in the Costa Almería is the summer, from June to August. The water temperature, especially in the eastern part, is comfortable enough July to September, although in September, which overall is still a good month (especially in the first half), the first Atlantic fronts begin to show up. May and June are sunny months, but the sea is still a bit cool, especially in May, when it is actually a bit cold.
Even though good weather is not always guaranteed, spring and autumn are ideal for visiting cities and going on excursions to the interior, since in summer the weather can be hot.
