The Western Algarve enjoys a Mediterranean climate, with hot dry summers and mild wet winters. In the summer, the heat is moderated by cooling north westerly Atlantic breezes.

The region enjoys an average of over 8 hours of sunshine per day, or 3,000 hours of sunshine annually. The period from the end of May until mid-September is dry, with only 6% of the annual rainfall occurring during that period. Most of the rainfall occurs between November and February. The annual rainfall averages 515 mm with a mean annual temperature of 17.9ºC. Average maximum and minimum daytime temperatures for the region are as follows:

	JAN	MAR	MAY	JUL	SEP	NOV
MAXºC	15	18	22	28	25	19
MINºC	9	11	14	19	18	13
MAXºF	60	64	71	83	78	66
MINºF	48	52	58	67	65	55

The temperature of the Atlantic water is fairly constant, typically varying between 14 to 18 degrees Celsius. In the summer, the higher inland temperatures over the Iberian land mass create an area of low pressure that sets up wind currents bringing in the cooler Atlantic air. Weather conditions near the Atlantic coast are thus more moderate than further inland.

The prevailing north westerly breezes tend to be stronger in the afternoons and also stronger in the summer months, when inland temperatures are at their highest.
