Marine Weather and Tide Forecast for Port O'Connor, TX

DISCUSSION
Issued at 120 PM CDT Sun Jun 7 2026

A sub-tropical jet streak and coastal troughing will keep moisture streaming into the area through at least Monday (PWAT values hovering between 1.95-2.25"). This will keep the mention of light rain in the forecast, particularly along the coast and over the Coastal Plains. By afternoon Monday, seabreeze convection could bring rain chances further inland and also result in heavier rainfall than is expected tonight.

High pressure will then settle in, warming temperatures back into the 90s across most of the area and near 100 across the Rio Grande Plains and northern Brush Country. With these warmer temperatures and minimum relative humidity values ranging from 40% inland to nearly 80% along the coast, heat index values will range from 100- 108 leading to a widespread Moderate Heat Risk (level 2 of 4), with areas of Major Heat Risk (level 3 of 4) through the end of the work week.

With respect to the rip current risk, persistent southeasterly winds and increased swell periods will keep the risk at high, though by Tuesday, winds decrease allowing for the risk to be more on the moderate side. With respect to coastal flooding, it still looks marginal for minor coastal flooding. At worst, it looks like motorists may briefly see tighter beach roads along the dunes, but this will be short-lived.
