Climate in St. Augustine Beach
St. Augustine Beach shares northeast Florida's humid subtropical climate, moderated somewhat by direct Atlantic proximity, and as an oceanfront community it carries storm-surge and beach-erosion exposure that inland St. Johns County communities don't share to the same degree.

Jacksonville-area daily highs -- the nearest long-term climate-normal station -- run in the mid-60s°F in January and around 90-92°F in July-August, though directly oceanfront communities like St. Augustine Beach typically see slightly cooler summer highs and milder winter lows than inland stations, thanks to the moderating effect of the Atlantic and a consistent sea breeze. Occasional hard freezes still reach this part of Florida, unlike central or south Florida.
Rainfall is substantial and concentrated in summer
Annual rainfall in the St. Johns County area runs in the roughly 50-53 inch range, concentrated heavily in summer thunderstorms -- a real contributor to local street flooding in low-lying parts of the city even outside of named storms.
Storm surge and coastal erosion are the direct, defining hazard here
Atlantic hurricane season runs June through November, and as a directly oceanfront community, St. Augustine Beach faces storm-surge and beach-erosion risk in a way inland St. Johns County communities (including Nocatee and St. Augustine's downtown core) don't share to the same degree -- confirm the current FEMA flood zone and any county evacuation-zone designation for a specific address before finalizing a purchase.
