In the second fortnight of August, daily maximum temperatures are likely to range between 33 and 34 deg C on most days, with daily maximum temperature possibly reaching a high of 35 deg C on a few days, the weatherman said.
It added that most nights may also be warm and humid, with temperatures staying above 27 deg C.
But localised short-duration thundery showers are also expected over parts of the island during the late morning and afternoon on some days.
There may also be several fair and occasionally windy days, MSS added.
Turning to dry conditions in the region, MSS said it has continued to observe hotspots with smoke plumes, mostly in the southern and central parts of Sumatra and various parts of Kalimantan.
It noted that dry conditions are expected to persist in the coming days, adding that Singapore may experience hazy conditions should the fires intensify.
This is due to the prevailing south-easterly or south-westerly winds, the agency said.
As at 5.50pm on Monday, the 24-hour Pollutant Standard Index (PSI) in Singapore remains within the moderate band.
Singapore experienced mostly dry conditions in the first fortnight of August, with only a few days of brief showers over Singapore.
Over this period, daily maximum temperatures exceeded 33 deg C on all but one day. The highest daily maximum temperature of 34.9 deg C was recorded at Pulau Ubin on Aug 14.
Well-below-average rainfall was recorded across the island in the first half of August, with Changi recording the highest anomaly of 100 per cent below average.
The highest rainfall recorded during the period was a daily total of 39.2mm at Seraya Road in Joo Chiat on Aug 2 and Paya Lebar on Aug 15.
