Weather in Nashville in August

Shoulder season. August is shoulder season in Nashville — cheaper, quieter, and a genuine gamble. Highs average 32.3 °C, lows 20.7 °C, and rain falls on 14 days — nothing in the month is working against you.

August ranks 8 of 12 in Nashville: past the worst of the year but short of October, which is the month to book if the dates are open.

Rain on 14 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 32.3 °C days and 20.7 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 6 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest August day reached 42.4 °C and the coldest night fell to 11 °C, and the wettest single day dropped 70 mm — roughly 69% of the month's rain in one day.

August is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest August on record still delivered 186 mm against 32 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 102 mm average is a reasonable planning figure, not a promise.

Wind is light at 4.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 70%.

How August sits in the year

Temperatures hold steady either side: 31.6 °C in July, 32.3 here, 29.2 in September. Nothing about the timing within the month matters much. Rain is the thing that moves: September brings 5 days less of it, so pushing the dates later buys drier weather.

Daylight in August

13.6 hours of daylight, losing 1 hours across the month. That is between Nashville's extremes of 14.6 and 9.7 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 34.3 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

August in Nashville versus nearby

If Nashville is one option among several, the nearby comparison is worth making. Huntsville is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Louisville is a better bet in August — within a degree on temperature, 2 days less rain.

So: August is a compromise. October is 30 points better and is what Nashville is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
