Climate and Water quality
The climate is mild and privileged. So much so that always spoke of the spring constant of the Mar Menor. It enjoys the warmest winters in the Peninsula, conducive to enjoying a quiet sunny and milder summers on the Mediterranean coast, thanks to the gentle breezes of Levante.
The average annual temperature is 17°C, and monthly averages for June, July, August and September are above 21°C. The winter is mild, because the average temperature of the cold months are not descended from 10°C.
Another highlight is the lack of rainfall, with less than 300 lm2 year. Dryness is key here, especially for its 320 days and 3,000 hours of sunshine annually.
Brief details of these that lead us to the privilege of enjoying a climate of gods, and are a tourist attraction, becoming the Mar Menor the ideal place for holidays throughout the year.
The water temperature is closely related to atmospheric temperature, as befits a relatively small body of water for the operating scale atmospheric processes.
This circumstance makes the thermal inertia of the lagoon is less than the Mediterranean. In the colder months the water temperature is around 1 º C while in August reached 30 ° C. be In certain areas of the banks, due to the limited depth can be recorded temperatures of 8 º C to 36 º C in summer. Moreover, the spatial distribution of the lagoon is uniform, the differences between different areas of less than 1-2 º C.
The salinity ranges between 42 0 / 00 and 47 0 / 00 compared to 36-38 0 / 00 in the Mediterranean. Throughout the year are somewhat higher values in September-October and minimum in January to May. Overall salinity values show a slight positive grandiante from north to south and from surface to bottom.
High temperatures and low rainfall, coupled with the absence of permanent freshwater inputs, makes the pond is in a deficit which is offset by the entry of water from the Mediterranean, resulting in the Mar Menor behaves like a bucket of concentration. Are easy to detect these entries of Mediterranean water in the mouths of the gorges by their different temperature and salinity.
The trade regime of the Mar Menor and the Mediterranean is determined primarily by the difference of water level relative to each other. Wind, evaporation and rainfall, influence the exchange gain or loss.
