Copano Bay, TX Daily Water Report — October 4, 2026

Copano Bay is broadly a go today, with boating the standout at 7.8/10 and a useful all-around mix for paddlers, divers, and anglers—provided you give the early gusts the respect they deserve. The bay is carrying modest 0.4–0.5 m waves, with the calmest water near 7 PM, while a 7-knot NNE representative wind masks a more energetic morning: gusts are forecast to top out near 25 knots around 8 AM. For fishing, the better timing is the sunrise major solunar period from 7:23 to 9:23 AM, followed by the evening major period from 7:23 to 9:23 PM. The morning overlap comes with the day’s strongest gust potential, so it favors protected-water plans and a firm grip on anything not tied down. Pressure is rising through the day, from roughly 1012 to 1017 hPa, and the high tide arrives at 11:08 AM before water drains toward the 10:12 PM low. Fishing rates 6.9/10, an improvement on yesterday’s 6.6. Kayaking scores 7.2/10 and diving 7.7/10. The late-day easing is the cleaner recreational window: waves bottom out around 0.4 m near 7 PM, and the evening solunar major begins shortly after. Marine water temperature is a notably warm 29.5 C, about 2.5 C above average. That does not substitute for site-specific visibility or safety checks; the reported 13.9 km visibility is atmospheric, not underwater. A current of about 0.33 m/s toward 219 degrees is also enough to matter for paddlers and anyone planning a water entry or return. Sailing is a middling 6/10: there is breeze, but the gust spread and heavy cloud cover make it less polished than the last few days. Boating has slipped from yesterday’s 8.6/10, largely a morning tradeoff rather than a washout. Wildlife scores 6.7/10, with the late low-tide approach worth watching from shore. The next three days look gentler on the water, with 0.2–0.4 m waves Monday and 0.2–0.3 m Tuesday and Wednesday; winds remain near 12 knots at peak. Best bet: launch late, let the morning gusts spend themselves, and use the 7 PM calm-water window into the evening solunar period.
