Localised short-duration thundery showers are expected over parts of Singapore in the late morning and afternoon on several days in the first half of September 2024, according to a Sep. 2 media advisory issued by the Meteorological Service Singapore. Additionally, Sumatra squalls may bring widespread thundery showers and gusty winds on one or two mornings in the latter half of the fortnight. The total rainfall for the first half of the month is forecast to be slightly below average to near average over most parts of Singapore.
## Background
The Meteorological Service Singapore’s forecast indicates a continuation of the weather patterns observed in the latter half of August 2024. During that period, localised short-duration thundery showers were common in the late morning and afternoon. The forecast for September suggests similar conditions, with the added possibility of Sumatra squalls contributing to the weather dynamics.
## Hot days & nights
The daily maximum temperatures are likely to range between 33°C and 34°C on most days in the first fortnight of September 2024. On a few days, the daily maximum temperatures may slightly exceed 34°C. Additionally, a few nights may be warm and humid, with temperatures staying above 28°C. This trend mirrors the conditions experienced in the latter half of August, where temperatures frequently reached similar highs.
## Similar to second fortnight of Aug. 2024
The weather forecast for the first half of September 2024 is similar to the weather conditions observed in the second fortnight of August. Over the last two weeks, localised short-duration thundery showers fell over parts of Singapore in the late morning and afternoon on most days. A notable temperature of 22.3°C was recorded at Admiralty at around 3 am on Aug. 28 as thunderstorms occurred over many areas of Singapore between 1:30 am and 3:30 am on that day. Despite these thunderstorms, most parts of the island recorded below-average rainfall in the second fortnight of August 2024. The daily maximum temperatures in the second half of the month ranged between 32°C and 34°C on most days, with the highest daily maximum temperature of 34.6°C recorded at Admiralty on Aug. 19 and at Pulau Ubin on Aug. 31.
## Future implications
The continuation of these weather patterns into September suggests that residents should prepare for similar conditions, including the potential for short-duration thundery showers and occasional Sumatra squalls. The forecasted temperatures indicate that both days and nights may remain warm, which could impact daily activities and energy consumption. Monitoring weather updates from the Meteorological Service Singapore will be crucial for staying informed about any significant changes or developments.
