Current Fishing Weather
Wind Speed and Direction
Wind Direction:
Wind Speed:
Wind Direction and Speed are one of the most important aspects for choosing a fishing spot. An offshore wind can help land-based anglers with longer casting distances, while an onshore wind will make kayak fishing safer. Often fish will also move to certain feeding areas depending on the wind direction. Check out the long term wind forecast at the charts below.
Fishing Barometer
Atmospheric Pressure:
Change since midnight:
Trend for next 6 hours:
Atmospheric or Barometric Pressure affects fish activity. The best fishing can be had on a rising barometer and also the time just before it is falling. A steady barometer in the higher ranges can also mean good fishing. A falling or low barometer reading without much change is usually not a very good time for fishing.
UV Effect on Fishing
As a rule of thumb, the higher the UV index, the deeper fish will move. Shallow water fishing is best done at times with a low UV index. When the UV is high, stick to early mornings, late evenings and shaded areas. The effect is less noticable in deeper water, but often a higher UV index can produce good results in the deep.

Fishing Overview San Marcos
Fishing in San Marcos, Texas revolves around the cold, clear San Marcos River and a network of nearby lakes and ponds that offer consistent action all year. The spring-fed flow keeps water temperatures relatively stable, so fish stay active even in winter, while lush vegetation, rock, and wood provide textbook habitat for bass, catfish, and sunfish. Whether you’re wading, kayaking, or bank fishing, the key is reading current seams, depth changes, and shade.
Seasonal patterns on the San Marcos River are subtle but important. In late winter and early spring, bass slide into slower pools and along gentle current edges; small soft plastics and suspending jerkbaits worked near bottom excel. As water warms in late spring and summer, bass and sunfish push shallow at first and last light, then tuck into current breaks, overhanging trees, bridge pilings, and deep undercut banks during mid-day. Topwater lures and poppers shine during low-light, while finesse worms, small jigs, and downsized crankbaits produce when the sun is high. Fall brings aggressive feeding—fish roam more, making reaction baits like small spinnerbaits, squarebills, and in-line spinners very effective.
The San Marcos River habitat is a mix of fast riffles, mid-depth runs, and deep, slow pools. Riffles and pocket water are prime for Guadalupe bass, small bass, and sunfish; target seams where fast water meets slow with small soft-plastic grubs, 1/16–1/8 oz jigs, or light spinners. In runs, focus on mid-channel depressions, submerged grass edges, and any isolated boulders that create a break in the current. Pools below dams, weirs, and bridge crossings often hold larger largemouth bass, catfish, carp, and gar—fish these patiently with bottom rigs or slow-rolled plastics.
Core techniques stay fairly consistent. For bass, a medium-light spinning setup with 6–10 lb line covers most situations. Weightless or lightly weighted stickbaits, small creature baits, and 3–4 inch finesse worms in natural colors (green pumpkin, watermelon, and shad patterns) are reliable producers in the river’s clear water. When visibility is high, go lighter on line and weights, and lengthen leaders. For power fishing, compact buzzbaits, walking topwaters, and small squarebill crankbaits draw reaction strikes around wood, grass edges, and shade lines.
Catfish and rough fish provide steady action for bait anglers. Channel and blue catfish key on deeper outside bends, below riffles, and any scour holes below manmade structure. Use simple slip-sinker or three-way rigs with cut shad, chicken liver, or stink baits placed just on the edge of current. Common carp and longnose gar cruise slower, open stretches and eddies; corn, dough baits, or small bread balls for carp, and cut bait or live bait for gar, fished with sturdy tackle and sharp hooks, are the most productive approaches.
Tactical tips for San Marcos include staying stealthy, especially in clear, shallow stretches: wade quietly, minimize surface noise from kayaks, and cast from a distance. Work upstream when possible to keep silt out of the fish’s line of sight. Polarized sunglasses are invaluable for spotting grass lines, submerged timber, and cruising fish. After rain events, slightly off-colored water often triggers better feeding—this is the time to throw bolder colors and higher-vibration lures. By matching your techniques to current speed, water clarity, and available cover, the San Marcos area can deliver highly consistent freshwater fishing throughout the year.
