Packery Channel, TX Daily Water Report — August 28, 2026

Packery Channel’s water today is a diver’s delight and a surfer’s shrug. The highest suitability rating goes to diving, which scores a 9.2 out of 10 — matching the best we’ve seen all week. The combination of light east winds averaging 9 knots, a modest swell under 0.3 meters, and a water temperature of 30.5°C makes for genuinely inviting conditions. Surface visibility should be very good in that 32-kilometer atmospheric clear air, and the tide cycle, with low water just before dawn and a slight high near midday, keeps currents manageable. The full moon overhead, rising at sunset, might add a little twilight intrigue for a late dip, but remember that moon phase also pulls stronger tidal swings; the actual range here today is only about 0.07 meters, so it’s a gentle one. If you’re heading out, the calmest wave period arrives around 1 p.m., when the sea settles to just 0.26 meters. Boating and sailing also look solid, both scoring above 8. The wind stays steady out of the east all day, gusting only into the low teens by evening. The representative 9-knot breeze is enough to fill a sail on open water without making the channel choppy — wave heights hold at 0.3 to 0.5 meters. That’s a half-meter improvement in consistency over yesterday, when winds were slightly weaker. For fishermen, the 6.9 score trails the 8.2 we saw two days ago, but the midday solunar minor period from noon to 2 p.m. aligns with the high tide slack, which often concentrates activity around structure. Chlorophyll sits at a moderate 0.66 milligrams per cubic meter, normal for this coastal zone, but that’s not a signal of bait or fish — just the typical summer productivity. Surfing is the odd man out at 4.5. The short-period swell at under 3 seconds barely registers, and wave heights are too low for any meaningful break. Kayakers get a fair 6.4; the morning low tide exposes some shoreline terrain to explore, but the easterly breeze picks up after lunch, so paddle early. The wildlife score of 6.6 is middling, partly because a full moon and low early tide can scatter bird activity, though the calmer water might keep birds working the channel edges. Compared to the past week, diving has been consistently excellent, and today is no exception. Looking ahead, Friday edges only slightly warmer with similar light winds, but by Saturday the breeze strengthens to 15 knots, making the late weekend better for sailing than paddling. Early next week we’ll see building swell and steadier east winds around 14-16 knots, which could push that surfing score up a point or two but also roughen the diving windows. For now, get in the water this afternoon — the sea is flat, the sun is high, and the channel is glass.
