Marine Weather and Tide Forecast for Riverside, TX

DISCUSSION
Issued at 1130 AM CST Sat Feb 28 2026

Onshore another warm day is in store for this afternoon. There's still a ~12F dewpoint gradient from north to south across SE Texas. Thus, RH values are expected to fall to generally 30-50% across inland areas and 50-80% near the coast. Highs should remain in the 70s/mid 80s with lows in the 50s/lower 60s. With onshore flow remaining in place and moisture poised to keep rising, sea fog will remain the primary hazard to focus on over the weekend, appearing in the bays/nearshore waters and coastline during the nighttime, then spreading inland and becoming more extensive during the early morning hours. Still, the broader extent and intensity of fog should wane heading into next week as waters slowly warm.

We're still expecting a few shortwaves & disturbances to pass north of our area next week. First of these occurs on Monday, where a cold front attempts to scoot its way towards SE Texas, but stalls near north-central Texas. The next front should be approaching SE Texas around mid week on Wednesday, but it too is anticipated to stall out near the Red River Valley. Even without the front, deeper moisture and shortwave energy overhead may still bring some showers and storms across the area beginning around mid week. Yet another front will try to push towards the area on Friday, but even this one appears to stall before reaching SE Texas. LREF Ensembles back the deterministic models, still showing strong consensus on a southerly wind direction all through the upcoming work week.
Cloud cover and showers may help shave off some of the heat, but warm weather will still dominate with highs in the 70s/mid 80s with lows in the 60s.

AVIATION
(12Z TAF Issuance)
Issued at 512 AM CST Sat Feb 28 2026

Satellite shows areas of patchy to dense fog expanding generally over the southern and western locations of Southeast TX. Thus, we will likely continue to see LIFR-MVFR vis and cigs for GLS, LBX, SGR, and HOU. Lower visibilities could also affect IAH and CLL, depending on how far northward the fog moves. Fog is expected to burn off and cigs will scatter out shortly after 14-15Z. However, conditions may be slower to improve over GLS and LBX due to persisting sea fog over the bays and nearshore Gulf waters. Expect SE winds at 6-12 KTS today, becoming light and VRB this evening.
We will once again see low vis and cigs tonight into Sun morning as fog re-develops over portions of Southeast TX.

Cotto

MARINE
Issued at 1130 AM CST Sat Feb 28 2026

Some patchy fog may linger in the coastal waters during the afternoon hours. Cannot rule out additional extensions of the marine fog advisory if conditions do not improve. Another round of fog is anticipated tonight into Sunday morning. Fog may be patchier in nature compared to previous nights, though anticipate larger increases in coverage and intensity by early Sunday morning. Still, warming water temperatures should start to decrease the chances for sea fog Sunday night into Monday as waters warm. Otherwise, expect light winds and low seas will continue through at least mid week.
