- Monsoon Update
(Updated on 1 June 2017)
Inter-Monsoon conditions transitioned to the Southwest Monsoon conditions in the last week of May 2017 and the prevailing light and variable winds gradually strengthened to blow from the southeast or southwest.
During the Southwest Monsoon season which usually extends from June to September, the monsoon rain band typically lies north of the Equator, and the weather during these months are generally drier compared to other times of the year.
In June 2017, Singapore and the surrounding region can expect dry weather conditions with fewer rain days compared to that in May 2017. With strong solar heating of land areas, Singapore could experience localised short-duration thundery showers mostly in the late morning and early afternoon on some days. In addition, thundery showers with gusty winds due to Sumatra squalls are common during the season, and typically affect the island between the pre-dawn and morning. Some warm days can be expected during the month where the daily maximum temperature could reach a high of around 35°C. On other days, the daily temperature is forecast to range between 25°C and 34°C.
During the season, Singapore could occasionally experience slightly hazy conditions on a few days, in particular in the early morning due to the accumulation of particulate matter under light wind conditions.
