The average annual temperature is 17ºC, and the average for the months of June, July, August and September is above 21ºC. Winter is very mild, with the average temperature of the cold months not falling below 10ºC.
Another point to emphasise is the scarce quantity of rain, with less than 300 sq. l. per year.
The dryness of the area is obvious, above all because of its 320 days and 3000 hours of sunshine a year.
These weather conditions allow us the privilege of savouring a climate of the Gods in the Mar Menor all year round.
The temperature of the water is closely related to the atmospheric temperature, as corresponds to a relatively small mass of water for the scale on which the atmospheric process operates. This situation makes the thermal inertia of the lagoon less than that of the Mediterranean.
In the coldest months the temperature of the water is about 1ºC while in August it reaches 30ºC. In certain places near the shore, due to the shallow water the range can be from 8ºC to 36ºC in high summer. On the other hand the spacial distribution of the water is uniform, with differences between the areas of only 1-2ºC.
The saltiness of the water ranges from 42 ‰ and 47 ‰ compared with 36-38 ‰ in the Mediterranean. During the year higher values can be found in September – October and minimum values in the period from January – May.
