Learn moreHot summers, mild winters
Per NOAA's 1991-2020 climate normals, the average annual temperature runs around 74°F. August is the hottest month, with average daily highs near 95°F, while January is the mildest, with overnight lows averaging around 48°F -- genuinely mild by comparison to most of the country, with essentially no sustained hard-freeze risk in a typical winter.
Rainfall is real but drier than several other Texas Gulf Coast cities
Annual rainfall averages 32.29 inches per the same NOAA normals -- notably drier than Houston or the upper Texas Gulf Coast. Precipitation is strongly seasonal: September alone averages about 5.4 inches, while February receives just over 1 inch, reflecting the concentration of rainfall in the late-summer tropical season.
Hurricane season overlaps directly with the wettest months
Atlantic hurricane season runs June through November, peaking August through October -- the same stretch as Corpus Christi's heaviest rainfall. See the insurance-hazard-costs topic for what that overlap means for insurance costs and storm history, and the moving topic for how it can affect relocation timing.
Coastal wind is a near-constant, non-hazard feature too
Beyond storm risk, Corpus Christi is known locally as a consistently windy city thanks to its open bay-and-Gulf exposure -- a real, everyday feature (popular with windsurfers and sailors on Corpus Christi Bay) distinct from and much more common than hurricane-force wind events.
