During 2008, the number of website user requests for data exceeded 56.9 million.
High temperatures in the hot and wet season (summer) typically exceed 90 °F (32 °C) across inland south Florida (although coastal locations are cooled by winds from the Gulf of Mexico and the Atlantic Ocean), while high temperatures in the dry winter season average from 70 to 79 °F (21 to 26 °C). Frost and freeze are rare across south ...
In these zones, summers are warm and winters are cold, but temperatures are not extreme. In subtropical zone wetlands, such as along the Gulf of Mexico, average temperatures might be 11 °C (52 °F). Wetlands in the tropics are subjected to much higher temperatures for a large portion of the year.
Climate. The tropical wet forests of North America have an average year-round temperature between 68 and 78.8 °F (26.0 °C). Thus, frost does not occur under these conditions. The temperatures remain fairly uniform throughout the year; therefore there is not a change of seasons.
The Pantanal is a tropical wet and dry region with an average annual temperate of 24 °C (75 °F) and rainfall between 1,000 and 1,250 millimetres (39 and 49 in) per year. Extreme temperatures can reach a high of 41 °C (106 °F) or drop to −1 °C (30 °F). [9]
