Being mountain guides we are also weather "freaks"! It is vitally important for us to know what is happening or going to happen in the high Sierras. We have collected together below the best and most comprehensive resources available to get the best and most complete picture of the inbound weather.
For the winter season (Nov to May each year) we have an avalanche risk information service and daily updates in English from AEMET, the most reliable mountain summary
If you are coming out here and want some help or advice re weather or snow conditions please use our Contact form. See also our report Aspects of weather forecasting in the Sierra Nevada mountains which may help.

Many misjudgements of the weather come from the changing of the seasons and the related mountain risks that brings. Traditionally, the autumn and spring are the most unpredictable, as it may be t-shirt and shorts weather on the Costa Tropical, yet people could well be fighting in blizzard conditions at 3000m. A fine day on the coast can lead unprepared people into the mountains unsuitably equipped. There have been accidents and in fact the Guardia Civil do place people at strategic access points during these times if they know bad weather is coming in, to check that trekkers are suitably aware and equipped.
Strangely enough, the winter is more predictable. Most mountain goers seem to know that we have severe weather then and at a bare minimum it will be very cold and windy. Similarly, summer is generally great high level walking and trekking with not too much required in the way of protective clothing save for the odd afternoon thunderstorm.
