Singapore, 1 December 2022 – The prevailing Northeast Monsoon conditions are expected to persist over the next few months. During this period, the low-level winds are forecast to blow mainly from the northwest or northeast. The current wet weather is likely to continue, with thundery showers expected on most days in the next fortnight.
2 Climatologically, December is the wettest month of the year. In the first half of December 2022, the monsoon rain band is forecast to lie close to the equator and bring shower activities to the surrounding region of Singapore. Short-duration moderate to heavy thundery showers are expected over parts of the island in the afternoon on most days. The showers may extend into the evening on occasions. In addition, in the early part of the fortnight, low-pressure systems developing in the region are forecast to bring a temporary shift in the winds to blow from the southwest or west over Singapore and the surrounding vicinity. This may result in the passage of Sumatra squalls bringing widespread thundery showers with occasional gusty winds in the morning on a few days. The total rainfall for the first fortnight of December 2022 is forecast to be near average over most parts of Singapore.
3 During the fortnight, the daily temperature is forecast to range between 24 and 33 degrees Celsius on most days. Although thundery showers are expected on most days, the daily maximum temperature could reach a high of around 34 degrees Celsius on a few days.
