What January feels like
The lightest crowds of the year on the River Walk, and the holiday lights usually hang on into the first week. A hard freeze arrives a handful of times each winter, and the city wraps its palms and its pipes accordingly.
Expect about 4 days with real rain — enough to notice, not enough to plan around. The air runs dry — whatever the thermometer says, it wears easy.
