The Met Office (AEMET) has extended the Yellow Alert for heatwave throughout Tenerife and the other Canaries. Temperatures are expected to remain over 30º on the coast, reaching high 30s at mid-altitude and altitude. In Gran Canaria, particularly, temperatures generally are expected to reach 37º today and 38º tomorrow, resulting in that island’s alert being raised to Orange.
In mid-altitude on the West coast temperatures have not gone below 32º for the last several days, and reached 40.6º yesterday: it is currently 40.5º in the shade in Vera de Erques. The present Yellow Alert is said to be in place from midday today until 7pm this evening, but other forecasts show this heatwave continuing throughout the week.
The situation is complicated by the arrival of a calima, which is simultaneously driving temperatures up and making it feel slightly more shady than it has done in full sun. The main problem associated with the calima is the winds that make the air feel like a fan oven, and which naturally raise fire hazards considerably. This is why the Fire Alert that was recently raised, posted below 25 July, will remain in place for the duration of the heatwave, with all mountain activities prohibited.
