In Costa de Almería, the portion of the Spanish southern coast in the province of Almería, the climate can be considered Mediterranean, with mild and relatively rainy winters, and hot and sunny summers, although the aridity is remarkable, so that the landscape is desert. There are several beaches that are located in a rocky and arid environment.
Geographically it is divided in a western part (Poniente Almeriense, where there are places like Adra, El Ejido, Berja, Roquetas de Mar, Almerimar, Enix and the nature reserve of Punta Entinas-Sabinar), a central part (where we find the Bay of Almería with the capital city, in addition to Cabo de Gata and Nijar), and an eastern part (Levante Almeriense, where we can find Carboneras, Mojacar, Garrucha, Vera, Pulpí, Cuevas del Almanzora, Villaricos). In the east, a short distance from Carboneras, there's the 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, in which the daytime temperature reaches or exceeds 20 degrees, even in winter. In winter, very cold days are rare, but on colder periods the minimum temperature can drop to about zero degrees; 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 touch even 38/40 °C.
Here are the average temperatures of Almería.

The rains in Costa Almería are decidedly scarce, as they are usually lower than 300 millimetres per year, and follow a 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, just 30 mm of rain fall. In the Cabo de Gata area, precipitation drops below 200 mm per year.
This is the average rainfall of Almería.

The amount of sunshine in Costa Almería is very good in summer, when clear skies prevail, it's good in spring, when cloudy periods are still possible, while it is still decent in autumn and winter, when in addition to sunny periods, which however are not lacking, cloudy days occur quite frequently. There are still on average six hours of sunshine per day even in December and January.

When to go

The best time for a beach holiday in Costa Almería is summer, from June to August. For swimming, the best time is from 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 making excursions into the interior, as in summer the weather can be hot.
