About
Lake Bostalsee (near Nohfelden) is an inland lake spot where windsurfing is the primary activity. The water is described as flat, with a pebble bottom and a spacious grassy rigging/launch area located at the windsurfing school side (Gonnesweiler on the northern shore). Wind at the lake is mainly driven by frontal/gradient patterns, with performance most dependable during low-pressure systems. Sources also describe gusty conditions, so riders should plan for variable strength rather than perfectly smooth sailing. For safety, kitesurfing is strictly forbidden on the lake, and windsurfing requires a basic windsurfing licence. The entry area is pebbly/stony and the comfortable standing zone is limited to roughly the first 10–15 meters; boots are recommended for getting in/out. The lake operates with designated zones to reduce conflicts with swimmers and other water users. Seasonally, the most favorable months for wind are reported in spring and autumn (notably April, May, September, October, and November). Temperatures range from very cold in winter to warm in mid-summer, with wetsuit thickness recommendations varying accordingly, and rescue presence commonly concentrated in the main season and weekends.
