KnotNow ratings answer: is this hour worth rigging for? — not just how windy it is.
Wind direction
Each spot has valid directions (e.g. cross-onshore for your launch). Off-direction wind may show strong speed but a low rating — watch the DIR row on the hourly grid and how it lines up with the compass at the top of the spot page.
Tide
Many locations prefer high or low tide within a window. The forecast highlights hours inside that window.
Water quality
Where we have live overflow data, recent discharges can affect the rating. Check the water-quality panel on the spot page.
