Seasons
Port Aransas fishing seasons
One page, not twelve: the month table below carries the sourced species timing from TPWD, the mean water temperature from the local NOAA station, and the honest note for each window. Detailed species pages land here once the new Texas license-year rules publish in September.

When should you fish Port Aransas?
Any month, for the right target: the bays hold redfish and trout year-round, the offshore peak stacks June through September, the bull redfish run owns early fall, and the flounder migration defines October into December. The table maps each month to its sourced strength.
| Month | Mean water temp* | What defines it | Worth knowing |
|---|---|---|---|
| January | 61.3°F | Winter trout and black drum on structure; the quiet month | Coldest water of the year — slow presentations, deeper holes |
| February | 60.9°F | Big black drum run; sheepshead spawn at the jetties | TPWD: February–March catches of large drum "make the local sports columns" |
| March | 67.9°F | Sheepshead spawn continues; bays wake up | Spring wind is the daily variable — the bays are the refuge |
| April | 74.7°F | Tripletail arrive; bay fishing hits stride | TPWD puts tripletail off Texas April through October |
| May | 81.4°F | Everything eats; offshore season builds | Water crosses 80°F — the summer pattern locks in |
| June | 85°F | Cobia and red snapper peak months begin | TPWD: cobia most common June–September; snapper spawn June–September |
| July | 84.9°F | Peak offshore; dawn trips beat the heat | Ferry queues peak too — cross before 5:30 a.m. |
| August | 86.5°F | Bull redfish staging begins near the passes | TPWD puts red drum spawning mid-August to mid-October |
| September | 85.8°F | The bull redfish run — TPWD’s own named phenomenon | Big reds at the jetties and beachfront; offshore still strong |
| October | 80.3°F | Fall flounder migration to the Gulf begins | TPWD: the run typically spans October–December through channels and passes |
| November | 71.7°F | Flounder run peak window; check current TPWD rules first | Fall flounder regulations are strict and change by license year |
| December | 64.9°F | Flounder tail end; winter trout begin | Water drops through the 60s — the quiet season, not a dead one |

One cross-reference worth the whole table: TPWD reports that male flounder head for the Gulf of Mexico when water temperature drops 4 to 5°C (TPWD flounder page). At this station, the average October-to-November drop across 2021–2025 was 4.8°C, computed from the same observations — which is why the run reliably lands in that window. And an honest gap: TPWD states plainly that “little is known of the tarpon’s spawning activity or growth” (TPWD tarpon page) — so unlike most sites, we publish no tarpon calendar.
How much does the season actually matter here?
Less than the day does. Port Aransas has a year-round fishery with seasonal peaks on top, and on any given date the wind, tide, and water clarity decide more than the month — which is why the live conditions report, not this table, should pick your actual day.
Use this page to aim the trip and the live report to pick the day. The species the table keeps pointing at have their own rule guides — redfish, trout, flounder, and snapper — and trip pricing by season moves too: peak weekends push toward the top of the price ranges.

Frequently asked questions
What is the best time to fish in Port Aransas?
For the widest menu, June through September — the sourced peaks for cobia, snapper, and the late-summer start of the bull redfish run all stack there. For a specific hunt, match the month to the species in the table above; redfish and trout make the bays worth fishing every month of the year.
What months are best for surf fishing?
The surf fishes on conditions more than the calendar, but the standout sourced window is late summer into fall, when TPWD puts red drum spawning mid-August to mid-October and big schools work the beachfront and passes. Calm green water makes any month workable.
