===Climate===

Despite their proximity to the Sahara, the Canary Islands have a relatively temperate climate. The [[sunshine duration]] is very high due to Teide's subtropical latitude and proximity to the [[Azores high]], as well as a very high [[UV index]] caused by the height of the peak (greater than 11 in the middle of the summer). This sunshine of around 3,450 h<ref name="OAPN" /> per year is partially compensated by the [[Canary current]], a relatively cold ocean current which makes the climate more temperate. The situation at the level of Teide and its caldera is very unlike the climate at its base. In effect, the climate of Tenerife is marked by an [[inversion (meteorology)|inversion layer]] around at an altitude of {{cvt|1000|m}}, isolating the high-altitude zones from ocean influences present at the lower altitudes. This leads to a more continental climate on Teide, with strong changes in temperature over the course of the day (typically on the order of 15 °C) and in the course of the year (with a range of -15 °C in winter to 30 °C in the summer).<ref name=whproposal />

Humidity is also very affected by this inversion layer. The presence of the Azores high in the northwest of the Canaries in summer induces relatively constant winds ([[trade winds]]) blowing from the northeast to the southwest. These winds carry moisture across the Atlantic and deliver rain to the north of Tenerife, forming in particular a dense layer of clouds between {{cvt|800|and|1600|ft}} of altitude. But the inversion layer also stops these clouds from rising, and the climate is thus very dry below the level of Teide. The precipitation in the caldera is thus less than 500 mm per year, the majority falling in the winter, and in total, around one third in the form of snow. Variation can be quite high from one year to the next. Meanwhile the peak of Teide is covered by [[wave clouds]], forming the "hat of Teide" ({{lang|es|Toca del Teide}}) which was probably confused with signs of an eruption by sailors.<ref name="OAPN" /><ref name=carratroll />
