Singapore is likely to experience hazy conditions in the week ahead despite the frequent showers over the past few years.
According to the National Environment Agency (NEA), occasional dry conditions over southern Sumatra are expected. As the winds over Singapore are expected to blow from the southwest at times, NEA said Singapore may be affected. The pollutant standards index (PSI) hit a high of 60 at 10am on Wednesday but reduced to 18 at 5pm. Link
