What March feels like
Bluebonnets come in along the highways south and east of town and peak before the Hill Country does. Spring break packs the River Walk and the theme parks — go early in the day or plan around it entirely.
Expect about 4 days with real rain — enough to notice, not enough to plan around. Humidity stays comfortable; the air never feels heavy.
