Singapore's Meteorological (Met) Service said in an advisory on Thursday that the first half of September is expected to be wetter than the last fortnight of August.
The authorities told Channel NewsAsia that there will be short thundery showers during the late morning and afternoon on seven or eight days. However, the prevailing southwest monsoon season will extend into the next month.
The advisory said that the widespread thundery showers are expected on one or two days between pre-dawn hours and the morning along with gusty winds. The Met Service added that the rainfall for this period is expected to be slightly above normal.
However, the daily temperature is expected to range between 24 and 33 degrees Celsius on most days. But, the temperature may fall as low as 22 degrees Celsius on a few rainy days or rise as high as 34 degrees Celsius on other days.
