How is lake surface chop calculated?
Chop on lakes is primarily driven by wind speed and fetch (the distance wind travels over water). Larger lakes with longer fetch produce bigger waves. Sheltered areas near shores often have calmer conditions.
What is fetch effect?
Fetch is the distance wind travels over open water. Longer fetch means more wave energy builds up. Shorelines on the windward side (where wind is blowing from) are typically calmer than leeward sides.
What do the condition ratings mean?
Good (green) means calm surface conditions suitable for most swimmers. Moderate (amber) means choppier water that may challenge some swimmers. Poor (red) means rough conditions not recommended for most people. Always assess the water yourself before entering.
What does the 7-day forecast show?
The forecast shows expected surface state (from glassy to rough) and wind speed for each day, colour-coded good/moderate/poor. Use it to choose your best day, but always check current conditions on arrival.
What about blue-green algae?
Blue-green algae (cyanobacteria) can produce toxins harmful to swimmers. Live algae data is not shown on this page. Always check Environment Agency and local authority advisories before swimming, and avoid water that looks green or blue-green, has surface scum, or smells musty.
