CatchWindow fishing intelligence

Bar Harbor, ME Daily Water Report — August 28, 2026

**Today’s verdict: Boating and kayaking get a near-perfect green light; the diving is very good too, and fishing is the most promising it’s been all week.** This is the kind of late-August day you wait for. The morning starts with the lowest tide of the month—just 0.05m at 5:33—so if you’re launching from a shallow ramp or exploring the intertidal, that’s your window for exposed ledges and tidepools. By mid-morning, the flood current pushes toward a 3.26m high at 11:39, and the afternoon ebb through the 5:44 low is equally workable. The wind is the real gift: a representative 3 knots from the south, gusting only to 13 knots, and the forecast range all day stays between 1 and 6.7 knots. That’s lighter than yesterday and about as calm as last Tuesday (August 25th), when kayaking scored 9.5. For paddlers, the boating score of 9.1 and kayaking 8.7 reflect those glassy windows, especially in the lee of the islands during the morning flood. Divers should take note: the water temperature is 16.8°C, which is a full 4 degrees above the long-term average for this date—the warmest reading in recent memory compared to the 17-18°C range we saw earlier this month. The diving score of 8.5 is only a shade below the 8.6-8.7 we logged on the three previous days, and with 12.3 km of atmospheric visibility, surface conditions are cooperative. Underwater visibility isn’t measured here, but the calm surface should keep the topside side of the experience clean. Surfing is a modest 5.8 out of 10, which is par for this week. The swell is 0.52m at 3.75 seconds from 177 degrees, meaning short-period, low-energy waves. The wind waves are even smaller at 0.26m. Not a day to plan a session around, but if you’re already on the water, there’s potential for a few rideable bumps on the south-facing beaches during the lower tide windows. Fishing jumps to 7.4, the highest score since August 24th’s 6.7. The solunar major period from 11:34 to 13:34 coincides with the high tide slack, and with a full moon overhead (100% illumination, rising at 19:20), the afternoon ebb should see increased activity. The chlorophyll reading suggests elevated biological productivity, but remember: that’s a water-quality metric, not a direct fish locator. The barometric pressure is stable at 1016 hPa, which typically holds feeding windows consistent. Looking ahead, Friday brings slightly cooler air (15.6-24.8°C) with peak wind around 11 knots and only a 4% rain chance, so the calm trend continues. Saturday and Sunday get messier—precipitation chances climb to 32% each day, though winds drop to 8.8 and 7 knots respectively. By next Tuesday, expect the smallest swell of the forecast period (0.2-0.2m) with waves dropping to nearly
