Copano Bay, TX Daily Water Report — October 8, 2026

Copano Bay gets a clear green light for boating today, with kayaking, sailing and diving also landing in the good-to-very-good column. The catch is not dramatic weather; it is the late-morning gustiness. Conditions are generally light, with north winds ranging from 3.2 to 9 knots, but gusts are forecast to reach 18.1 knots around 10 AM. That is enough to make an otherwise civilized bay feel briefly less civilized, especially for smaller craft and anyone setting sail. The smoothest water arrives near 6 AM, when waves bottom out around 0.3 metres. Through the day, seas hold in a modest 0.3 to 0.5 m range, with a representative 0.32 m wave height and short 4.35-second period. A small east-southeast swell of 0.28 m is present, while wind waves remain slight. Boating earns 8.7/10, a touch better than yesterday’s 8.6 and among the stronger recent ratings. Kayaking rates 7.5/10 and sailing 7.5/10: both workable, but the gust spread argues for an early launch and a conservative plan once the morning breeze starts flexing. Fishing scores 6.5/10, matching October 6 and improving on yesterday’s 5.9. The most promising timing overlaps the late-morning solunar major period, 10:49 AM to 12:49 PM, though it also coincides with the day’s strongest projected gust. The evening minor period, 5:19 to 6:19 PM, leads into the 6:42 PM high tide and may offer a calmer tradeoff. Tidal movement is extremely small overall, with heights only ranging from 0.03 to 0.08 m. Diving rates 7.8/10, supported by light waves, light wind and warm 28.6 C marine surface water. The reported 12.5 km visibility is atmospheric visibility, not a reading of underwater clarity. Expect a warm, dry day with no rain indicated, temperatures rising to 31.2 C, and pressure climbing from roughly 1012 hPa. Friday stays similarly manageable, with 0.4 m waves and peak wind near 8.6 knots. The weekend remains low-wave but breezier, with peak winds around 12 to 13 knots. Best bet: launch early for the bay’s calmest water, then let the late-morning gusts decide how ambitious the rest of the day gets.
