Port Isabel, TX Daily Water Report — August 25, 2026

Today is a stellar day for diving off Port Isabel, with a near-perfect score of 9.1 out of 10. The conditions are optimal, thanks to calm seas and excellent clarity, making it a diver's delight. Boaters and sailors will also find the day favorable, with conditions rated at 8.2 and 7.7, respectively. The southern winds are moderate, ranging from 5.4 to 13.2 knots, providing just enough breeze for a pleasant sail without being overpowering. Fishing enthusiasts should aim for the solunar major periods, particularly the late morning slot from 10:16 to 12:16, to make the most of a 7.1 out of 10 score. The waxing gibbous moon, at 90% illumination, might not be the best for night fishing, but it certainly sets a nice backdrop for an evening on the water. Surfing, however, remains lackluster with a score of 4.9. The waves are gentle, peaking at just 0.42 meters, and the short period of 3.95 seconds isn't offering much to ride. Kayakers will find the waters manageable, especially around 9:00 a.m. when wave heights are at their calmest at 0.38 meters. Compared to the past few days, conditions are quite stable with slight improvements in kayaking and wildlife activity scores. Wildlife watchers can enjoy a 7.2 out of 10 rating today, a jump from earlier this week, likely due to better timing with the solunar periods and low-tide proximity. Looking ahead, the weather stays warm and mostly dry, with temperatures creeping up to 33.7°C by the weekend. Winds will increase slightly, peaking at 15.9 knots on the 28th, which could make for more dynamic sailing conditions. For the best experience today, divers should hit the water early to enjoy the clearest conditions and minimal wave activity.
