WEEK AT A GLANCE
Daytime highs range from 86°F to 89°F, overnight lows 80°F to 82°F. Winds predominantly out of the SSE.
OUR READ ON THE WEEK
Steady SSE and S winds in the 9-to-15 mph range will hold all week, which means the surf stays stirred and water clarity along the beachfront stays limited — east-of-south wind angles push Gulf churn straight into the passes and the near-shore zone. The bay side gets some protection, but that persistent onshore push will keep a light chop running across the open Corpus Christi Bay flats and through the ship channel, so smaller skiffs should plan for a bumpy crossing most mornings. Tides this week are worth paying attention to: the swings are modest early in the week — we're talking less than half a foot of exchange Monday and Tuesday — then build steadily toward the weekend, with Saturday and Sunday showing a full foot of range and the lowest lows dropping to -0.3 feet late in the evening. That growing exchange mid-to-late week means current through the cuts and shoreline drains will run noticeably harder by Friday and Saturday. Friday's chance of afternoon rain showers is the one wildcard; a quick storm cell can spike lightning risk fast out here, and we'd watch that sky well before it gets close. Temps stay deep into the 80s around the clock all seven days, so heat management on the water — shade, hydration, early starts — isn't optional this week, it's the plan.
