Around three in the afternoon, Canary Islands time, this Wednesday, June 21, summer will officially begin in the Islands and will last until September 23. This phenomenon called solstice has some very special characteristics: it is the longest day of the year and, therefore, the shortest night.


Right from this Wednesday, a process begins in which the days with hours of sunshine will shorten as the season goes by. On this occasion, the duration of summer will be 93 days and 16 hours, until September 23, the day on which autumn will begin with the phenomenon known as the equinox.


Although summers in Lanzarote are usually mild and pleasant, this year it will be especially hot in Spain. There is between 50% and 70% chance of having a summer that is warmer than normal, a more pronounced circumstance in the archipelagos.


As for spring, it has been verified that the March-April-May quarter has been the warmest recorded in the Canary Islands since 1961, with an average temperature of 19.6 ºC in the province of Las Palmas (thermal anomaly of 1.8 ºC ) and 17.1ºC in Santa Cruz de Tenerife (anomaly of around 2ºC).


There have been very warm temperatures in practically all areas of the archipelago and compared to March and April, the warmest since 1961, May has been the eleventh warmest since that year.


In any case, the islands are preparing to enjoy the traditional night of San Juan, a custom that marks the beginning of summer on the islands.
