CatchWindow fishing intelligence

SPI Brazos Santiago, TX Daily Water Report — October 4, 2026

The call is favorable for sailors and divers, workable for boaters and anglers, and a little more demanding for paddlers than the scorecard alone might suggest. A northerly breeze is doing most of the sorting: it ranges from light early to roughly 18 knots later, with gusts reaching 22 knots around 9 PM. Seas stay modest at 0.6–0.9 m, but the short 5-second wave rhythm and building wind mean the water may feel busier than the headline height suggests. The most useful all-around window is early morning through the 7:24–9:24 AM solunar major period. It overlaps daylight, follows the overnight high tide, and arrives before the stronger part of the northerly flow. Fishing earns a 6.7/10 under the combined solunar, tide, pressure, wind, and available clarity inputs; the rising 1014 hPa pressure is a constructive part of that setup, though wind will be the limiting factor as the day develops. The next major solunar period, 7:24–9:24 PM, comes after sunset and near the day’s strongest gusts, so it is more a timing note than an invitation to stretch a plan. For sailing, the 8.7/10 reflects a useful breeze with manageable wave heights, though gust spread deserves respect. Boating rates 6.6/10 and kayaking 6.4/10: both are best handled early, before the north wind turns routine crossings and exposed water into work. The calmest seas are forecast near 3 PM at 0.58 m, but that is not necessarily the calmest wind window. Diving rates 8.6/10, supported by warm 30.1 C marine water and relatively low seas; atmospheric visibility of 14 km is not an underwater-visibility reading, so dive conditions still need on-site confirmation. Compared with yesterday, wind is notably stronger—17 knots representative versus 10.3—and boating has slipped from 8.1 to 6.6, while sailing remains strong. Water remains warm, about 1.3 C above average. Low tide arrives at 4:09 PM, a useful reference for shoreline explorers, with the usual exposed-ground tradeoff rather than a guarantee of easy access. Monday and Tuesday keep waves near 0.6–0.8 m but bring 20-knot-plus peak winds and increasing rain chances; Wednesday looks somewhat less windy before seas build later in the week. Best bet: launch early, use the morning major period, and be heading in before the northerly starts charging rent.
