Rainbow Bridge, TX Daily Water Report — October 6, 2026

Rainbow Bridge gets a clear go for boating and sailing today, with a qualified yes for paddlers, divers, and anglers. The water is unusually tame: waves run just 0.1 to 0.2 m, with a representative 0.18 m chop and only a small 0.06 m swell. That supports the day’s strongest activity marks, 7.8/10 for both boating and sailing. A northeast breeze around 7 knots, gusting near 13, is enough to keep sails interested without making the surface argumentative; the strongest gusts were forecast before sunrise. The best all-around window is late afternoon into early evening. Winds ease within a 2.6-to-8-knot daily range, and the calmest water is forecast near 7 PM at just 0.08 m—after sunset, so use the daylight portion before 6:57 PM for travel and setup. For anglers, the 9:01-11:01 AM solunar major period is the more practical daylight opportunity, with another minor period from 3:31-4:31 PM. Fishing rates a respectable 6.3/10, down from 6.9 yesterday, with falling pressure and a very small tidal range offering less of a push than the calendar might suggest. Diving earns 7.1/10, helped by warm 28.8 C water and light seas, but it is not a blank-check visibility day. CoastWatch chlorophyll is very high at 9.83 mg/m³, indicating bloom conditions; that can compromise water clarity. The reported 23 km atmospheric visibility is excellent for navigation and horizon checks, not a measure of what divers will see below the surface. Kayaking is workable at 6.5/10, especially in the lighter-wind daylight hours, but the early gust potential and fading light deserve respect. Compared with recent CatchWindow estimates, boating improves slightly from yesterday’s 7.6, sailing holds steady at 7.8, while diving and fishing soften from 7.6 and 6.9. No rain is indicated, skies are nearly clear, and the air warms from about 20.5 C to 31.6 C. Wednesday and Thursday stay warm and mostly light-wind with tiny waves; conditions get breezier and a little more unsettled Friday and Saturday before easing again Sunday. Best bet: launch or rig in the late afternoon, enjoy the low chop before sunset, and let the water—not the warm forecast—set the pace.
