Climate in Fleming Island
Fleming Island shares northeast Florida's humid subtropical climate, and because it sits inland on a river/lake peninsula rather than on the open coast, its hurricane-season risk runs more toward river and lake flooding than coastal storm surge.

Jacksonville-area daily highs -- the nearest long-term climate-normal station to Fleming Island -- run in the mid-60s°F in January (with overnight lows in the low-to-mid 40s°F) and around 90-92°F in July-August (with overnight lows in the mid-70s°F). Unlike Tampa or points further south, northeast Florida sees occasional hard freezes and, rarely, snow flurries -- a January 2018 winter storm brought measurable snow flurries to the Jacksonville area, a widely reported event underscoring that this isn't a frost-free climate.
Rainfall is substantial and concentrated in summer
Annual rainfall in the Jacksonville/Clay County area runs in the roughly 50-53 inch range, concentrated heavily in summer thunderstorms -- a real driver of Doctors Lake and St. Johns River water levels during the wettest stretches of the year.
Hurricane season means river and lake flooding here more than coastal storm surge
Atlantic hurricane season runs June through November. Because Fleming Island sits inland on a peninsula between Doctors Lake and the St. Johns River rather than on the open Atlantic coast, the more directly relevant hurricane hazard here is river/lake flooding from heavy rainfall and storm runoff rather than coastal storm surge -- confirm the FEMA flood zone for any specific address, particularly near the shoreline of either waterway.
Key takeaways
- Humid subtropical climate: daily highs in the mid-60s°F in January and around 90-92°F in July-August, based on Jacksonville-area climate normals.
- About 50-53 inches of annual rainfall, concentrated in the summer wet season; occasional hard freezes and rare snow flurries (January 2018) set northeast Florida apart from central/south Florida.
- Hurricane season (June-November) matters here primarily through Doctors Lake/St. Johns River flooding, not coastal storm surge -- Fleming Island isn't an oceanfront community.
- Confirm the FEMA flood zone for any address near either waterway shoreline.
