A steady range of high temperatures from 24.5°C (76.1°F) to 28.8°C (83.8°F) and low temperatures from 23°C (73.4°F) to 27.5°C (81.5°F) can be monitored each month. This equatorial position results in nearly constant daylight hours, steady at 12.1 hours throughout the year.
However, notable variations exist in terms of rainfall and sunshine. The rainfall patterns are quite distinctive, with a significant increase from 9mm (0.35") in July to a hefty 224mm (8.82") in November.
