The reputation of El Medano as being a world-class all-year-round Watersports destination has come about from an extremely consistent northeast trade wind named “Alisios” which allows 365 days of cross-onshore conditions suited for beginners towards pro-athletes. When checking wind forecasts for the area, a key tip is to add 5 - 10 knots on whatever Windguru is predicting when in a north-easterly direction, as the wind accelerates around the huge volcano of Mount Teide.
The most accurate forecast is the one from muchoviento.net. The entire bay can be transformed into a freestyle paradise through the arrival of southerly winds, these can also be a lot stronger than what is forecasted. This combined with air temperatures that go almost never above 32 degrees and not below 20 degrees, even in winter time makes El Medano the perfect Watersports holiday destination.
