Researches about thermal dynamics of the wetlands soil has not been explored in order to have a better understanding of this dynamic in the region, making it necessary studies to explain their properties in order to contribute to the understanding of this biome. Thus, this study examined the variability of the average soil heat flow through a characteristic day of each season: rainy and dry, the region has a seasonal flood pulse and rainfall, affecting the exchange of energy between the surface and atmosphere. It was made analysis of the influence of thermal conductivity and thermal gradient in the values of heat flow in soil. It was observed variability of soil thermal components followed the flood pulse of the Pantanal region, because presence of water was essential for the seasonal variation of soil heat flux, temperature gradient and thermal conductivity of soil in the Pantanal.
