Climatology

The average temperature of the geographical area is 20º C, with thermal variations between the cooler and the warmest months and the average difference in temperature between January and August being around 7º C.

 

The daily thermal contrast on this island can reach up to 17 ºC in the same day and these variations, between day and night are considered typical for desert nature.

 

The average annual rainfall is less than 150mm. With regard to seasonal variation, it should be noted, that the rainiest month is December, most of the annual rainfall occurs between the months of November and March and is virtually non-existent between the months of June and August.

 

Due to the shortage of geographic barriers and the influence both of the trade winds and sea breezes, the wind in particular is a distinguishing factor in Lanzarote.  The constant wind throughout the year gives rise to some of the characteristic agricultural practices of Lanzarote.

 

The direction of the wind that predominates is the N-NE, with the highest concentration and speed occurring during the summer months, when the trade winds are the greatest, with a medium annual wind speed ranging between 5 and 7 m/s.

 

The relative humidity as a climatic variable factor may be considered relatively high, having  registered relative humidity with an annual average of 69 % with significant seasonal variations, with maximum values of 72% in months of highest average  (December and January) and a minimum of 66% in the months with lower average (April and May).

 

Also important are the daily movements, registering maximum values of more than 80 %, in the first hour of the morning and minimum values of less than 40% by midday, coinciding with peak hours of heatstroke.

 

The low cloud cover, a widespread feature throughout the year, favours the high number of hours of solar radiation, obtaining an average value of 7.8 hours/day. It is a fact that there are variations in the numbers of hours of sunlight between the various stations, giving the maximum value for Summer (9.5 hours/day), intermediate values in Spring and Autumn (8 hours/day and 7 hours/day respectively) and minimum in Winter (6 hours/day) AEMET 2010
