the county's south being prone to shorter, more frequent thunderstorms especially in the late summer. Freezing temperatures occur only every 2–3 years, with freezing precipitation occurring extremely rarely. Springs are usually short, mild, and dry, with occasional late-season cold fronts. Summertime weather is very consistent, with highs in the low 90s °F (around 32 °C), lows in the mid-70s °F (around 24 °C), accompanied by high humidity and an almost daily chance of afternoon thundershowers. The area experiences significant rainfall during its summer months (approximately May through October), with nearly two-thirds of annual precipitation falling between the months of June and September. The area is occasionally affected by tropical storms and hurricanes, but has not suffered a direct hit since 1921. Fall, like spring, is usually mild and dry, with the hurricane season extending through November and sometimes affecting the area. Many portions of south Pinellas, especially near the bay and gulf, have tropical microclimates. Tropical trees such as coconut palms and royal palms and fruit trees like mangoes grow very well in these microclimates.
