Source: NOAA 1991 to 2020 U.S. Climate Normals for the Thompson Station, TN station (USC00408953), read October 16, 2026. Normals are 30-year averages; any single year runs warmer, colder, wetter or drier.

How much rain does Thompson's Station get, and when?

Thompson's Station gets about 56 inches of rain a year, spread through every month. December is the wettest on average at 5.8 inches, followed by April and February at about 5.3 and 5.2 inches. August is the driest at 3.6 inches. The heavy spring and winter rain is why I look hard at gutters, grading and crawl space moisture on every house I show here.

What does Thompson's Station weather mean for a house?

Air conditioning. With June through August lows in the mid to upper 60s and highs near 90, the air conditioner runs for months. Ask for the age and service history of the HVAC system during your inspection period.

Drainage. Fifty-six inches of rain, with December, April and February the heaviest, means lot grading and gutters matter, especially on larger lots. French drains and swales are common in local yards for a reason.

Crawl spaces and basements. Summer humidity makes a dry, encapsulated crawl space worth paying attention to. Dehumidifiers are a normal sight in basements here.

Outdoor living. Covered porches and screened patios get used from April through October. Ceiling fans on a porch are a small thing that makes a big difference in July.

When is the best time of year for Thompson's Station parks and trails?

April, May, September and October, when the average highs run from the low 70s to the low 80s. Preservation Park is the Town's roughly 200-acre park, most of it kept in a natural state, with the Battlefield Trail and a greenway that the Town says forms the backbone of its trail system. The greenway also runs from Nutro Dog Park, a four-acre Town park at Columbia Pike and Critz Lane, north to Tollgate Village and south to Preservation Park. In July and August, go early or late in the day.

How does the weather affect the commute to Nashville?

With no traffic, Thompson's Station Town Hall to the Tennessee State Capitol is about 40 minutes by I-65, and rush hour adds to that in any season. Winter rarely closes roads, but frost and the occasional ice on I-65 overpasses can slow the morning drive in January and February, usually clearing by midday. US-31 is the alternate route north toward Franklin when the interstate backs up. My commute times page has the rush-hour picture.
