Port Mansfield Channel / Mansfield Cut is a lower Texas Coast pass fishery linking Lower Laguna Madre with Gulf water through a remote jettied entrance. Red drum and spotted seatrout are principal targets, with flounder adding another important inshore opportunity around the channel and adjacent shoreline.
Current Coastal Rating

Beta
Conditions are fair, but confidence is reduced because some coastal inputs are partial or prediction-based.
Scores are model-specific and are not directly comparable across water types.
Should I Go?
Trip conditions only. Target-species activity and seasonal fishery patterns are not yet included.
Consider
Trip conditions may be workable, but important cautions or data limitations remain.
High confidence in the evaluated inputs — observational coverage is partial. — Required data sources were available and the key inputs were current.
Evaluates trip conditions using weather, tides, currents, waves, daylight, and active alerts.
This coastal rating is in public beta.
Missing waves are not calm. Forecast is not an observation. Prediction is not an observation.
Because this rating is in public beta, recommendations are capped at Consider when evidence is limited.

Fishery Profile
Fishery Overview
Port Mansfield Channel / Mansfield Cut fishery
A Lower Texas Coast cut fishery at the Mansfield Channel through Padre Island. USACE-maintained jetties and the Gulf pass concentrate red drum, spotted seatrout, southern flounder, sheepshead, and snook moving between Lower Laguna Madre and the Gulf. This is the Mansfield Cut / Gulf-pass destination.

Fishery Targets
Red drum, spotted seatrout, and sheepshead are Mansfield Cut targets. They occur here, but they are not typical every month. Southern flounder typically use channels and passes during fall emigration toward Gulf spawning, generally October through December per TPWD; that is not year-round occupancy at this Gulf entrance and is not a legal harvest season. Snook is a Lower Coast jetty fish at Port Mansfield and is warm-water limited;.

Access, Safety and Regulations
Access
NPS: fishing is popular along the jetties. Reaching the Gulf-side cut overland from Padre Island National Seashore requires a four-wheel-drive vehicle on the island/beach route; NPS states there is no vehicle crossing to South Padre Island from here. Boat access is from Port Mansfield through the USACE-maintained channel. Confirm current NPS, refuge, and Corps postings.
Primary hazards
Remote location, four-wheel-drive beach travel, strong current, barge traffic, and slick granite are the primary hazards. Do not attempt to cross the channel by vehicle. Heat, lightning, and limited cell coverage are routine Lower Coast risks.
Fishery considerations
Tidal exchange through the Mansfield Cut is the local fishing context. Wind, currents, and waves are not shown with conditions.
The Gulf mouth is exposed. Wind and swell can make the jetties unsafe even when the inner channel looks calm.
Regulations
Size limits, seasons, and possession rules change. Verify the current official regulations before fishing.
The map marker represents the cataloged waterbody or monitoring location and may not indicate legal parking or public access. Confirm access through the official information before visiting.
