The three-hour Pollutant Standards Index (PSI) at 4pm on Saturday fell to 85 from 122 an hour earlier. This is now the lowest PSI reading since Tuesday morning's 9am reading of 84.
The 24 hour average PSI at 4pm also dipped to a 167-187 range from 170-193.
Air in the 51-100 reading is considered "moderate", while the 101 to 200 PSI range is considered "unhealthy". Anything above 300 is hazardous, while readings between 201 and 300 are very unhealthy.
While many are out enjoying the sunshine and improved air quality, others, including MPs, still felt that it is too early to be optimistic just yet.
"The wind and weather are kind at the moment and the haze appears to be better. But this is likely to be temporary, so we are continuing our efforts to make sure the elderly, low-income and vulnerable are looked after," MP for Pasir Ris Punggol GRC, Dr Janil Puthucheary.
"Much clearer skies today both in town and in Queenstown!" said Tanjong Pagar GRC MP Chia Shi-Lu. "Wishing everyone a healthy, happy and haze-free weekend... do take care and look out for those around you."
