Port Aransas Fishing Report: Week of Jul 13, 2026

WEEK AT A GLANCE

Daytime highs range from 86°F to 87°F, overnight lows 82°F to 83°F. Winds predominantly out of the SSE.

OUR READ ON THE WEEK

The SSE wind holds at 16 mph through the weekend before backing off toward 7 to 12 mph by mid-week, so expect a steady push of Gulf air and a consistent chop in the ship channel and the surf zone through at least Sunday. East-southeast wind components like these tend to work against water clarity on the beachfront — that onshore angle keeps the surf stirred — while more protected shorelines on the bay's western and northern reaches should stay calmer and clearer. Tide swings this week are notably compressed; the early-week range runs just under two feet and the weekend transitions to a mixed semi-diurnal pattern where highs and lows barely separate, meaning current exchange through the passes and flats will be sluggish rather than strong. By Saturday and Sunday the tidal variance shrinks to well under a foot between the highs and lows, so don't count on moving water to do much work for you on those days. The saving grace is the moderate air temps — highs in the mid-to-upper 80s with overnight lows only dipping to 82°F — which keeps heat stress manageable on the water, though we'd still recommend early starts before the full sun loads up on a flat, windless bay. Watch for conditions to improve meaningfully by Tuesday through Thursday as winds ease and the bay surface has a real chance to settle down.
