April 5th in Chattanooga tends to land right in that sweet spot of spring — average highs of 64° with almost no chance of snow. The spread can be wide though: this date has seen a balmy 82° (just this year) and a teeth-chattering 30° back in 2007.
Chattanooga keeps things interesting year-round — and occasionally extreme. The city has touched 100° in summer heat and plunged to -6° in a brutal December cold snap, with a single-day rainfall record of 8.4 inches that should give any flood-wary traveler pause.
Summer is the main event here, with highs in the low-to-mid 80s from July through August and a peak around July 16–22. Winters are mild but not toothless — January averages just 45° — and late September is historically the wettest stretch of the year, so pack accordingly.
