Inter-Monsoon Conditions Expected By End-October 2022
Wet weather expected to continue for the rest of Oct 2022
Singapore, 17 October 2022 – The current wet weather is expected to continue for the rest of October 2022. The prevailing Southwest Monsoon conditions, with low-level winds blowing from the southeast or west, are forecast to gradually weaken to become light and variable in direction by the end of October 2022. The shift in wind conditions signals the end of the Southwest Monsoon and the start of the inter-monsoon period.
The inter-monsoon conditions are forecast to last through November 2022. During the inter-monsoon period, the monsoon rain band lies close to the equatorial region, and more showers can be expected over Singapore and the surrounding vicinity. Lightning activity tends to be higher during the inter-monsoon months than other months of the year.
In the coming fortnight, thundery showers are expected on most days. On some days in the earlier half of the fortnight, the presence of low-pressure systems over the South China Sea may induce the development of Sumatra squalls in the Strait of Malacca and bring widespread thundery showers with gusty winds to Singapore and the surrounding vicinity between the pre-dawn hours and morning. In the latter half of the fortnight, afternoon thundery showers are forecast on most days, with the showers extending into the evening on a few of these days. On a few days, widespread moderate to heavy thundery showers may occur, due to large-scale convergence of winds over Singapore and the surrounding region. Overall, the rainfall for October 2022 is expected to be well above-average over most parts of Singapore.
For the rest of October 2022, the daily temperature on most days is forecast to range between 24 and 33 degrees Celsius. Although showers are expected on most days in the coming fortnight, the daily maximum temperature could still reach a high of around 34 degrees Celsius on a few days. In addition, the wet weather may bring daily temperatures of between 23 and 32 degrees Celsius on a few days.
