- Monsoon Update
(Updated on 6 August 2017)
Southwest monsoon conditions are forecast to persist in August 2017 with low level winds blowing from the southeast or southwest. The Southwest Monsoon season which extends from June to October is generally drier compared to other times of the year.
For August 2017, the prevailing winds are forecast to blow from southeast or southwest. Thundery showers due to solar heating of land areas are expected to occur mostly in the late morning and early afternoon. Furthermore, widespread thundery showers accompanied by gusty winds due to the passage of a Sumatra squall can be expected in the predawn and early morning on a few days.
In August 2017, periods of drier weather can be expected which could contribute to an increase in hotspot activities in the region and may lead to the occurrence of transboundary haze. Occasional slightly hazy conditions are likely on a few days, in particular in the mornings due to the accumulation of particulate matter when winds are light.
On most days in August 2017, the daily temperature is forecast to range between 25°C and 33°C. The daily maximum temperature could reach as high as 34°C and the daily minimum temperature could reach a low of 23°C on a few rainy days. Nights can be relatively warm, in particular on fair weather days. This usually occurs when the winds are light and blow from the southeast, bringing warm, humid air from the sea towards the land.
