Bodensee Seelotse

One lake, your profile. Lake Constance Guide brings together everything you need on and around Lake Constance—tailored to your activity: sailing, motorboating, kayaking, stand-up paddleboarding (SUP), windsurfing, wing foiling, waterskiing, swimming, or diving.

STORM AND THUNDERSTORM WARNINGS AS PUSH DELIVERY
Official DWD (German Weather Service) warnings for western, central, and eastern regions—sent directly to your device as a push notification, with the all-clear signal. The app now also warns of thunderstorms, fog, and heavy rain along the shoreline, around the clock. And honestly: if the warning service is down or the data is unclear, the app tells you so, instead of incorrectly displaying "no warning." With the Premium version, you can also select your own gust warning levels (25/35/45 km/h) for each region.

LIVE CONDITIONS AT A GLANCE

Wind and gust data from measuring stations around the lake (DWD, MeteoSwiss, GeoSphere Austria), water levels at Konstanz and Romanshorn, water temperature, UV index, sunshine duration — and a condition indicator with a MOSMIX forecast for your spot. For divers: a visibility estimate for the Rhine Delta, calculated from the Alpine Rhine flow (BAFU).

INTERACTIVE LAKE MAP
Over 300 harbors, lakeside gas stations, and access points with details (address, phone, services), over 80 official bathing areas with water quality information, live wind arrows, rain radar with forecast (Premium), warning zones, ferry routes, offline map for the entire lake area (Premium) — and your location on request. New: the wind field (Premium) — wind arrows across the entire lake in a 1 km grid, up to 3 hours ahead. The wind field is experimental. We continuously compare the forecast with actual weather stations.

DATA SAVING
No ad tracking, no account required, location remains on your device.

Important: Only official storm warning lights on the shore are legally binding. The app provides supplementary information and does not replace official nautical charts or your own assessment of the situation.
