Fernandina Beach, FL Daily Water Report — August 28, 2026

Get on the water early this morning and you'll find the best conditions of the day, especially for boaters and divers. A high tide just after 9:30 AM will give you deep water over the bars and reefs, and with the full moon overhead, the tidal exchange is strong and the currents will be moving. The south wind is light, only 4 knots representative, and the sea is mirror-flat with an average wave height of just 0.4 meters and a modest 0.26-meter swell from the east-southeast. Boating scores an 8.7 out of 10, the highest we've seen in the last week, and diving is right there with an 8.3, thanks to the calm surface and warm 28.7°C water that's nearly a half-degree above the long-term average for late August. The tradeoff here is that the full moon's bright face will be up all night and setting at 7:17 AM this morning, so the minor solunar period around sunrise will have some pull, but the major feeding windows fall during the low-light hours before dawn and again in the early afternoon. The low tide at 3:18 AM and the one at 3:26 PM both bottom out just above zero, meaning exposed flats and shallow oyster bars for the midday kayak or wildlife paddle—kayaking scores a 7.6 and wildlife watching a 6.8, both solid but not outstanding compared to the string of 8-plus days we had over the weekend. Fishing sits at 6.9, which is actually a tick down from yesterday's 7.4, so don't expect a bonanza; the rising pressure and calm conditions can make fish sluggish during the bright middle hours. Surfing remains marginal at 5.6, with short-period wind chop and no real groundswell to speak of. The wave range stays between 0.3 and 0.5 meters all day, and by evening the sea will be at its calmest around 7 PM, just 0.34 meters, which is great for a sunset paddle but not for a surf session. Sailing scores a 5.9, held back by the light and variable breeze that never tops 8 knots out of the south; you'll need to work to keep the rail down. Looking ahead, Friday brings slightly stronger wind near 8.5 knots and a 29% chance of showers, so the morning window will be your best bet again. The weekend looks warmer and drier, with highs approaching 33°C and seas staying under half a meter through Monday—perfect for a long holiday weekend on the water. Best bet: catch the outgoing tide this afternoon from the high at 9:33 AM through the low at 3:26 PM for a drifting kayak trip with minimal chop and maximum wildlife viewing.
