What August feels like
August is when the lawns go brown and the water restrictions get serious — the Edwards Aquifer level is genuine small talk here. Schools go back mid-month, which takes some pressure off the water parks for the last two weeks.
Expect about 3 days with real rain — enough to notice, not enough to plan around. It’s sticky — light fabrics and an afternoon break earn their keep. Most afternoons push past 90°.
