Hazards

Shallow lagoon water with potential underwater vegetation and debris requiring careful navigationLow average wind speeds (8.5 kts) requiring discipline to avoid getting stuck in flat spellsVariable wind directions with frequent lulls typical of inland reservoir conditionsSummer algae blooms common in Central European reservoirs affecting water quality

Launch notes

The flat lagoon water provides excellent conditions for progression and tricks, with easy beach launches from the sandy shore. Best launches occur with SSW or W winds when thermal effects are strongest in afternoon sessions.

Gear & clothing

Gear · Bring 14-17m kites to maximize light wind potential, with 12m as backup for stronger days. A directional or twin-tip board works best for the flat water conditions and light wind characteristics.

Clothing · A 3/2mm wetsuit suffices April-October; upgrade to 5/4mm or thicker for winter sessions (December-March) as Central European inland waters are cold. Air temperatures can be cool even in shoulder seasons.

Crowd & etiquette

Respect local swimmers and windsurfers sharing the lagoon, particularly on weekends. Follow any local club guidelines and keep clear of designated swimming areas.

Additional notes

Nové Mlýny reservoir is Czech's largest water body, offering consistent conditions but requiring patience with light winds; plan sessions for afternoon thermal development. Check local wind forecasts carefully as 41 windy days yearly means many sessions will be marginal.
