Seasonal variations brought about by north-south movements Hadley Cells which greatly affected 2–7 year cycle east-west movement El Nino Southern Oscillation. Temperatures mean monthly maxima minima ranging 31–38 °C 13–25 °C, respectively. Relative humidity also 09.00 h values 60–80%, 15.00 30–70%.
