Rainbow Bridge, TX Daily Water Report — August 23, 2026

Rainbow Bridge is a paddler’s and small-boat day, not a sail or surf day. Kayaking leads at 9 out of 10 and boating follows at 8.6, both better than yesterday’s 6.9 and 7.9 when the breeze was stiffer. Sailing has fallen hard from yesterday’s 9.2 to 4.8, and surfing stays a thin 4.5 on a barely-there sea. Those scores describe suitability, not a safety promise. The water is almost flat: waves 0.1 to 0.2 meters, calmest near noon at 0.1 meters, with a short period around three seconds and a light swell from the south-southwest. Current is slack. Representative wind is only about 3 knots from the west-northwest, but the forecast is not uniformly gentle. Speeds run from under 2 knots to 14.5, and the strongest gust, near 19 knots, is due around 18:00. That late puff is the day’s real tradeoff. Air is muggy and overcast, already feeling like 33 C under 81 percent humidity, with a climb toward 36 C and almost no rain on the board. Pressure is steady near 1017 hPa. UV is negligible under full cloud, and atmospheric visibility is a comfortable 16.6 kilometers—that is not a read on the water column. High tide is a modest 0.30 meters at 08:26, then the tide eases toward a late low of -0.04 meters at 23:50. The morning solunar major, 08:21 to 10:21, sits on that high and is the cleanest fishing window on a middling 5.8, a notch under yesterday. Wildlife is only a 6; the useful low sits after dark. Diving holds at 6.8, same as yesterday, on quiet surface and 30.5 C water that matches the seasonal average. Chlorophyll is very high at 9.83 mg/m3; treat that as water-color context, not a fish forecast, and do not confuse it with clarity. Through midweek the marine forecast stays pancake-flat and the heat holds, with rain chances staying low until they creep into the low 20s later in the week. Best bet: put a kayak or small boat in during the still morning and be wrapping up before that 18:00 gust.
