REVIEW (1 – 28 February 2023)
5 Northeast Monsoon conditions prevailed over Singapore and the surrounding region in February 2023. The low-level winds blew from the northwest or northeast.
6 The second half of February 2023 was generally dry until the end of the month. On 28 February 2023, the strengthening of the high-pressure system over the northern Asian continent brought a surge of strong north-easterly winds (or monsoon surge) over the South China Sea. The monsoon surge brought widespread continuous moderate to heavy thundery showers over Singapore and the surrounding region with all stations across the island recording more than 100mm of rainfall. The rain was heaviest over the eastern and southern parts of Singapore with the highest daily total rainfall of 225.5mm recorded at Kallang. This was the highest daily total rainfall ever recorded in February, exceeding the previous record of 159.3mm on 4 February 1995
7 In February 2023, the daily maximum temperature was below 33 degrees Celsius on most days. The highest daily maximum temperature of 34.2 degrees Celsius was recorded at Ang Mo Kio on 10 February 2023 while the lowest daily minimum temperature of 21.3 degrees Celsius was recorded at Jurong on 15 February 2023.
8 Well above average rainfall was received across the island in February 2023. The highest anomaly of 281 per cent above average was recorded at around Tanjong Katong area. The anomaly was lowest at Mandai at 81 per cent above average.
 A monsoon surge refers to a strengthening of winds over the South China Sea, causing extensive rainclouds to form over our surrounding region. Read more at http://www.weather.gov.sg/learn_weather_systems/
