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

DISCUSSION
Issued at 1236 PM CDT Tue Oct 14 2025

With the cancellation of the Coastal Flood Advisory earlier this morning, the general trend for the remainder of the work weak is a decreasing one. This weekend, swell periods increase to near or above 7 seconds, however a south/southeasterly onshore flow will help keep the coastal flood risk down.

At the upper levels, ridging will continue to keep drier air across much of the South. On the southern periphery of this ridge, an inverted trough is circling around the ridge with a more inverted trough like feature moving onshore late Wednesday and being absorbed into a trough moving in from the Intermountain West. At the surface, this will increase chances for rain primarily in the open waters of the Gulf and more so towards Southeast Texas. The Victoria Crossroads have a 10-20% PoPs Friday, but that pretty much is the extent of any mentionable PoPs for this forecast package. As the aforementioned trough moves through Texas this weekend, a surface cold front will also move through the region, though not so much with any noticeable temperature drop. This will primarily be one in which dewpoint temperatures drop as drier air filters in behind the front. Min RH's drop from the 35-40% across the Brush Country on Saturday to Min RH's as low as 25% for the same area on Sunday. While winds will remain behind the frontal passage, this will still need to be monitored for any fire concerns given the low RH values.

Temperature wise, low temperatures across the inland zones will still bottom out in the low to mid 60s for the next two mornings, before climbing back into the upper 60s/low 70s for the remainder of the week. Highs will still climb into the mid to upper 90s across the Brush Country this week, allowing the Heat Risk to climb to a Moderate risk during the peak heating of the day.

AVIATION
(18Z TAFS)
Issued at 1236 PM CDT Tue Oct 14 2025

Weak, scattered showers continue to move in from the Gulf into the Coastal Plains (primarily south of KCRP). This area of shower activity is forecast to continue pushing toward KLRD through mid- afternoon. No major reductions in visibility expected with these showers, so only brief reductions to MVFR due to CIGs . Tonight, winds become light and variable with a low chance of fog in the Brush Country, so added in fog in a TEMPO line for KALI.

MARINE
Issued at 1236 PM CDT Tue Oct 14 2025

A gentle breeze (BF 3) Wednesday and Thursday. The flow is expected to strengthen to moderate (BF 4) out of the southeast by Friday. Low (5-20%) rain chances expected through the week.

FIRE WEATHER
Issued at 1233 AM CDT Tue Oct 14 2025

Minimum RH values will generally remain above 30% through most of the period and the ERC forecast will be at 70-90th percentile across the inland Coastal Plains and Brush Country. However, a generally weak east to southeast wind should preclude any fire weather threats. The chance for wetting rains is low to medium (10-40%)
this afternoon across the southern Coastal Bend to the southern Brush Country. Low to very low chances expected the remainder of the week.
