|Gran Canaria weather forecast for July 2012: Scorchio!|
Shade temperatures above about 35 degrees C trigger a yellow tempeerature alert in the Canary Islands. At around 38 degrees C the alert goes to orange (I've never found an exact definition: I think it depends on how long the high temperatures last).
Heat waves in the Canary Islands are caused by huge masses of hot air moving off the Sahara Desert and heading out over the Atlantic Ocean. This is why they are almost always accompanied by dusty air, yellow skies and a hot, south wind. The phenomenon is known as Sirocco or Calima in the Canary Islands.
After the tragic deaths of two hikers in May this year, everyone is very aware of the dangers of going walking or running up in the mountains. You get heatsroke within an hour of being in the sun. Dyhydration causes walkers to become disorientated and clumsy and causes accidents. Please don't go walking in the hills this week as it is downright dangerous!
The good news about the heat is that scientific research has revealed that drinking a cold pint of beer rehydrates you faster than a cold pint of water. Who's round is it?
