Maldives is characterized by a warm and humid tropical monsoon climate with an annual mean temperature of 28°C. The islands experience little variation in temperatures throughout the year. The seasonal cycle is strongest in the north recording an average maximum temperature of around 29.3°C just prior to the onset of the southwest monsoons (April-May) and an average minimum temperature of around 27.4°C prior to the onset of the northeast monsoons (December-January). The southern equatorial regions experience precipitation throughout the year and do not experience a very significant dry spell related to the northeast monsoons.
- In 1969-1999, the annual average maximum and annual average minimum temperatures in Malé (central region) show a rising trend of 0.17°C and 0.07°C per decade respectively.
- A more recent temperature record from 1995-2004 compares the trend in annual average maximum temperatures between the northern, central and southern atolls. An increasing trend is observed for central and northern regions, with the northern atolls showing a more pronounced increase. The southern atolls do not show any visible trend in the short-term record of annual average maximum temperatures.
- The analysis of annual rainfall totals from 1969-1998 for Malé (central) and Gan (south) shows a decreasing trend of around 2.7 mm/year and 7.6 mm/year respectively.
- Further, on analyzing the seasonal average precipitation for the same period at Malé, it can be seen that the decreasing trend is visible only during the southwest monsoon season, while no significant trend is observed during the northeast monsoon.
