What Spring Hill's Weather Is Actually Like

Spring Hill sits on the mild edge of the humid subtropical zone — same classification as Nashville, Atlanta, and Charlotte. The shape of the year is a gentle arc: winters that barely dip below freezing on average, a summer plateau in the low 90s, and shoulder seasons that deliver weeks of perfect weather.

Roughly 50 inches of rain a year — a third more than the US average — spread evenly enough that there's no real dry season. Snow is a guest appearance: under five inches a year and rarely sticking more than a day. Ice, not snow, is the real winter hazard here.

The thing nobody from California fully believes until they experience it. Relative humidity sits around 70% year-round, but what matters is the dew point — and from June through September, it lives in the upper 60s. Step outside in July and you'll feel the air.

208 days a year with at least some sunshine — better than Cleveland, on par with Philadelphia. The latitude gives you long summer evenings (past 8pm in June) and early winter darkness (sunset before 5 in December). The curve below is purely geometric, a product of 35.75°N.

The year told twelve ways. Each card shows where that month sits in the annual temperature arc — the dot is you.

This is the section Californians ask about first. Spring Hill sits in what meteorologists now call “Dixie Alley” — the eastward-shifted zone where tornado frequency has risen over the last three decades. Middle Tennessee averages about 30 tornadoes per year, and more than two-thirds of state tornadoes strike here. Tennessee tornadoes are more often nocturnal than Plains tornadoes, which is part of why the state leads the nation in night-tornado fatality rates.

The unspoken cost of living in green country. Humid climate, dense vegetation, and a seven-month growing season add up to a year-round allergen cycle. Nashville ranks #32on AAFA's 2026 Allergy Capitals list.

If you've never had allergies before, there's a decent chance you'll develop them within a year or two of moving here. Transplants from dry climates — California and the Mountain West — feel this most.
