First heatwave of 2013 this weekend

Update 19 April: It’s over 30º at altitude and we have the Sahara at gale force through the garden. This is going to last at least another couple of days, and the government has issued the following health advice. Much is common sense, but it’s worth repeating.

In particular, be aware that symptoms of being heat-affected include fainting or lightheadedness, nausea, and palpitations. Children might become irritable and lose their appetite. The Health department says that with calimas, too, the elderly, those with chronic illnesses, and particularly those with respiratory problems should take extra care, and advise anyone feeling any symptoms to try to cool themselves immediately, drink water, and if they do not feel better very quickly, to seek medical help.

General advice to protect from sun and heat is:

  • to stay in places shaded from the sun and in the cooler rooms
  • to keep the blinds down during sunlight hours
  • to open windows overnight to cool dwellings
  • to use fans or air conditioning to cool the environment where possible
  • to be careful of dramatic temperature variations when changing environments
  • to avoid direct sunlight, and if going out is inevitable, wear a cap or a hat, and lightweight, light coloured clothing, and try to walk through shaded areas or with an umbrella for protection, taking breaks in cool places
  • to carry water always and sip it frequently
  • not to leave children or elderly people inside a closed car
  • to avoid strenuous activities in the central hours of the day
  • to eat light meals and refreshments rich in water and mineral salts, such as fruits and vegetables, which help to replenish salts lost by sweating
  • not to drink alcoholic beverages
  • to help others, particularly those who might be sick or old people, living alone
  • to consult a doctor if you are taking medication that can influence your body’s ability to regulate temperature
  • to call 112 for any information

Update 18 April: As expected, the alert has now been extended to cover the western islands. Tomorrow Friday will have a yellow alert for temperatures to 35º in Tenerife as well as Gran Canaria, Lanzarote and Fuerteventura. On Saturday, the alert is raised to orange for temperatures to 37º in Tenerife, the eastern islands, and La Gomera (El Hierro and La Palma will be on yellow alert on Saturday. The alerts last from 10am to 8pm, and will be the result of a calima which will also affect air quality. This is expected to last until Monday.

Original post 17 April: It’s going to be a warm weekend. A blast of warm African air is heading our way, with temperatures of up to 30º expected in Tenerife, up to 34º in the eastern province, where Aemet has raised 2013’s first yellow heatwave alert. It’s expected to be extended westwards in due course.
