In the basin, there are significant temperature differences; temperatures are low during the rainy season and at night during the dry season. Generally, dry seasons are long, about 8 months. Precipitations are limited and occur within a few days. The annual temperature cycles display a typical north-south gradient, influenced by the position of the sun and by cloud cover. An increase in cloud cover during the course of the wet season inhibits solar radiation and therefore causes temperatures to drop. This is evident in the arid and semi-arid areas where the seasonal contrast between periods with and without cloud cover is stronger. Towards the south, where clouds and rain feature throughout almost the entire year, the temperature cycles vary less compared with those of the north, where spikes in temperature can be very sharp. Polygons show the temperature differences measured by the weather stations over the past few years.
