I use both windalert and windfinder in the US. They work globally too. Depending on what sensor they are reading you will find that one site or the
other is better at real-time data in your area.
Windalert seems to be better at real-time data and Windfinder seems to be better for forecasting.
On the website, windfinder also has this cool "super forecast" feature that when you click it, it turns the next three mediocre wind-day forecast into
awesome super consistent wind days. :D Maybe that's why they call it super forecast.
Too many kites, boards, and etceteras.
