Best low-tide window in Brownsville
The next low tide is around 6:12 PM at 0.4 ft — the window when flats, sandbars, and tide pools are most exposed for clamming, shore fishing, and tide-pooling. Water turns and starts rising back toward the next high around 3:19 AM, so give yourself a wide margin and head back well before then.
The water turns and returns quickly once the tide starts rising. Watch for slick rocks, soft mud, and rip currents, mind the next high-tide time, and follow local shellfishing regulations and closures.
