Best with Thermal, Bise, Northwest and West wind. The thermal wind gets a bit accelerated here due to the high mountains. Thermal wind blows often from 1-6pm. Several different winds blow on Urnersee: Fohn (S), strong (6-9 Bft) and warm wind, but also many times gusty. Fohnbise (S, before Fohn), up to 5 Bft, constant. The stronger the Fohnbise, the stronger the Fohn will be. BE carefull, the wind can quickly change to Fohn and become strong, look out for a green line on the water to see the Fohn hitting. Thermal wind (N), blows on sunny days in spring and summer with 2-4 Bft. Bise (N), cold wind, which can be nice with thermal support, strongest, if Brunnen has fog and in the Urnerland the sun shines, constant in Sisikon, gusty at the south end of the lake. Nordwestwind (N, NW) can get strong, but blows rarely, and only about 30 min before cold fronts. Westwind (W) is really rare. With rain there is never wind, just before the rain starts.

Check local rules for kitesurfing.
