🌡 The weather here, in general

Chattanooga runs the full range. The warmest stretch, around July, averages a high near 88°F, while January nights average 33°F — a 55-degree spread, so a coat that works in January is useless by July and the other way round.

The thermometer rarely spikes — only about 33 days a year top 90°F — but it hardly needs to. Summer sits in the mid-eighties for months at a stretch, and with humidity on top of it the heat index runs well above what the air temperature suggests.

Snow is rare, but 41 nights a year drop to freezing. Burst pipes and black ice are the practical concerns, not shovelling.

It is a wet place: about 57 inches of precipitation a year, peaking in February. Drainage and flash flooding deserve more attention here than in most of the country.
