Singapore, 16 February 2023 – The prevailing Northeast Monsoon conditions are forecast to continue into the second fortnight of February 2023. For the next two weeks, the low-level winds over Singapore and the surrounding region are forecast to blow mostly from the northeast or northwest.
2 The second half of February 2023 is expected to be drier than the first half of the month. The presence of a dry air mass may bring relatively fair and occasionally windy conditions to Singapore on a few days in the coming fortnight. Localised short-duration thundery showers, due to convergence of prevailing winds with the sea breeze, can still be expected in the afternoon over parts of the island on some days. Overall, near average rainfall can be expected for the second half of February 2023 and the total rainfall for the month is likely be above average over most parts of the island.
3 For the rest of February 2023, the daily temperatures are forecast to range between 24 degrees Celsius and 33 degrees Celsius on most days. The maximum temperature could reach around 34 degrees Celsius on days with little or no rain.
