A mass of warm, dry air began to move in across the peninsular on Sunday and thermometers have shot up, especially in the southern half of the country, where temperatures of over 38ºC are expected today.
Specifically, 29 provinces are on extreme heat alert on Monday. Madrid, Seville, Toledo, Cordoba, Jaen, Ciudad Real, Badajoz, Cáceres, Fuerteventura, Gran Canaria and Lanzarote, where the mercury could shoot past 40ºC, are all on orange alert (significant risk).
The Spanish Met. office is maintaining the threat until Thursday, with a yellow alert activated in Zaragoza, Valencia, Alicante, Murcia, Cádiz, Granada, Huelva, Málaga, Albacete, Cuenca, Guadalajara, Avila, Salamanca, Segovia, Tenerife, La Palma and El Hierro, which could all see highs of up to 39ºC.
Lows are unlikely to fall below 20ºC all week in the Mediterranean, central and southern peninsula. This will push the UV index up as high as 11 in a number of different parts of the country.
Fuerteventura, Gran Canaria and Lanzarote are on yellow alert today for airborne dust, due to the mass of warm, dry air which is affecting the Canary Islands and much of the peninsula.
The unusually high temperatures are forecast to stay with us until Thursday, when they will fall slightly in Galicia and the Canary Islands.
Civil Protection officers recommend drinking plenty of water and eating only light meals during the the heatwave, and wearing light-coloured clothing, covering most the body, especially the head.
Experts also suggest avoiding prolonged exercise in the middle of the day and warned against leaving children or the elderly inside a closed vehicle.
