Light Calima this week

Forecast of dust concentration for Thursday, Dec. 6th 2018, a bank holiday in Spain

A very stable and blocking high pressure system over the Iberian peninsula and North Africa is steering an easterly airflow over the Canary Islands and this is not expected to change for the remainder of the week. It is bringing very dry and warm air from the Sahara, and from later today some dust is expected resulting in mostly sunny weather with a light Calima (click for more information).

Thankfully the Sahara is not too hot at this time of the year and recent rains over North Africa have kept the dust down, so the effects on the Canaries should be minor, but warmer than usual temperatures, dry air with mainly fresh easterly winds, strong and gusty at times, will be felt here. Make sure to drink enough water.

The weather should return to normal over the weekend, when the winds are expected to turn back to the usual NE trade winds bringing clearer air, according to most forecasting models.
