Although located some distance north of the geographic tropics, Hamilton has a warm trade-wind tropical rainforest climate (''Af'') bordering on humid subtropical climate (''Cfa''). It is warm enough for coconut palms and other tropical palms to grow, although they may not fruit properly due to the lack of heat or sunshine during the winter months because of latitude. Hamilton has uncharacteristically warm temperatures for its latitude (32°N) because of the moderating influence of the North Atlantic and nearby Gulf Stream. Hamilton features warm and humid summers and semi-warm "winters". As temperatures are moderated by the Atlantic Ocean, it rarely gets very hot or cold in the city. Precipitation is plentiful throughout the year and Hamilton does not have a dry season month, a month where on average less than  of precipitation falls. Summer precipitation is usually from showers, thunderstorms, and tropical disturbances or even tropical cyclones. Meanwhile, winter precipitation is typically derived from westerly moving extra-tropical cyclones and their associated fronts. Erratic, extended dry spells occasionally develop because of variations in the semi-permanent sub-tropical ridge locally known as the Bermuda-Azores High.
