Regional context
Sonterra's climate, drawn from NOAA NCEI 1991-2020 normals at the nearest station, runs warm year-round with a milder seasonal range. July means peak near 84°F and January settles around 48°F — a 36°F swing reflecting the lower-latitude position at 30.8°N. Yearly precipitation totals roughly 37.1 inches over about 54 rainy days.
Rainfall stays relatively even across the calendar: May tops out at 4.3 inches across 5.8 days with measurable rain, and July settles around 2.2 inches across 3.4 rainy days — a comparatively narrow seasonal range. That even-rainfall rhythm puts Sonterra alongside places like Jarrell, TX, Weir, TX and Bartlett, TX — places without a single dominant storm season, where moisture arrives steadily across the calendar.
Hard freezes are uncommon here: the coldest month averages 48°F, well above the freezing threshold, so the growing window stretches across most of the year. Cool-season crops can be planted in late fall through early spring, and warm-season transplants tolerate the local winter unless an unusual frontal passage drops temperatures below the 30-year normal. The hottest stretch arrives in August at a mean of 84°F, which limits cool-season vegetables to the shoulder months on either side of the summer peak. The figures above are 30-year normals; outlier years can deliver brief cold spells the averages don't show. Inside Sonterra, low-lying parcels and inland positions typically lose 3-5°F of overnight low temperature versus coastal or elevated lots, which expands the practical cold-risk window by a few days.
