Mayport (Bar Pilots Dock), FL Daily Water Report — August 28, 2026

**Suitability Verdict:** Today is a top-tier boating and diving day at Mayport, with conditions that have been holding steady for nearly a week. The gentle south wind and near-flat seas create an inviting window for anyone looking to get on the water, especially during the morning outgoing tide. The big story is the remarkable consistency. We’re looking at a representative southerly breeze of just 3 knots, gusting to 8, with waves averaging 0.36 meters at a 6.4-second period. That’s a long, sleepy swell from the east that barely registers. The calmsest stretch should come around 7:00 PM, when waves drop to 0.3 meters. The marine forecast shows this pattern has been the norm—yesterday’s boating and diving scores were similarly strong, and today’s 8.7 for boating actually edges out the 8.0 from yesterday. For divers, the water temperature sits at a warm 27.5°C, which is nearly a full degree above the long-term average, and the 8.3 diving score is right in line with the excellent scores we’ve seen all week. The one significant tradeoff for anglers is the midday low tide. Fishing scores a 6.9, which is a step down from yesterday’s 7.8, largely because the solunar minor period at 7:00 AM coincides with the outgoing tide, but the major period runs from 12:28 to 2:28 PM right through the low-water slack. That combination can be hit or miss—fish may be concentrated in deeper channels, but the rising barometer at 1018 hPa suggests stable, high-pressure feeding. The chlorine reading of 2.48 mg/m³ indicates rich water, which can attract bait, though it’s worth noting this is a satellite measurement of surface chlorophyll, not a direct observation of fish activity. For surfers and sailors, this is a calm, not a classic day. Surf scores 5.4 with a 0.2-meter swell from the east at 6.7 seconds—clean but small. Sailors get a 5.6, and with peak wind gusts hitting 20.4 knots at 4:00 PM, there’s a brief window for a lively afternoon reach if you’re rigged for light air. The next few days look like a carbon copy: light winds, small waves, and rising temperatures pushing toward 33°C by midweek. Precipitation chances stay low through the weekend. Best bet today: Launch by 8:00 AM for the high-tide ebb, and plan to anchor up near the bar for the slack before the afternoon sea breeze fills in.
