Grand Isle, LA Daily Water Report — August 24, 2026

Today at Grand Isle, LA, the water is looking friendly for sailors and boaters, with scores of 7.6 and 7.3 out of 10, respectively. The steady ENE wind at 9 knots provides a nice push for sails without being overpowering, and the calm wave heights between 0.2 and 0.3 meters make for a smooth ride. Early risers will find the calmest waters just before dawn around 04:00, at 0.22 meters. For those with fishing on the agenda, a 6.6/10 score suggests decent conditions, especially during the solunar peak from 08:56 to 10:56. Just be aware of the very high chlorophyll levels indicating a bloom, which could affect water clarity. While this might not impact your catch, it’s something to consider if you're particular about the aesthetics of the water. Surfers might want to hold off today, as the 5.2/10 score reflects the modest wave action and short period swells. Divers and kayakers share a 6.6/10 rating, with the warm sea surface temperature of 32°C providing a comfortable environment, albeit with limited visibility due to the chlorophyll levels. Looking back, today's conditions are a bit calmer than yesterday's, with slightly lower wind speeds and wave heights. The weather remains stable with a barometric pressure holding at 1018 hPa and only a slight chance of rain in the evening. As we look ahead, expect some changes with wind speeds increasing tomorrow and a higher chance of rain by the weekend. For the best bet today, set sail early to enjoy the calm waters and mild winds before the evening rain rolls in.
