The temperature in Austin, TX has been in the 80s, maybe the 70s. It's supposed to get down to 50 degrees later this week. The weather has been great for fishing. I caught a bunch of Rio Grande perch, Guadalupe bass, sunfish, and largemouths last weekend. It will time to fish for 20"+ trout on the Guadlupe River in another month.
The middle of summer is the only bad time for fishing around here. Even then, the fishing on the gulf coast is good. It's just a 4.5 hour drive.
