Where our forecast data comes from

KnotNow uses weather and marine data from trusted sources to build wind, tide, and conditions forecasts for winging spots across the UK and Ireland.

Wind and weather

Wind speed and direction, temperature, and precipitation are derived from numerical weather models and observations. Conditions can change; always check the day and use your judgment.

Tides

Tide times and heights are based on official tidal predictions for the nearest primary station. Local bathymetry and weather can affect actual water levels at each spot.

Forecasts are for recreational planning only. Do not rely on them for safety-critical decisions. Always assess conditions on site and prioritise safety.
