Current forecasts from Singapore's meteorological authorities indicate a daily maximum of 28°C on May 16, supported by persistent cloud cover and scattered showers typical of the inter-monsoon season that reduce incoming solar radiation and limit surface heating. This stable tropical regime produces narrow diurnal temperature ranges near the equator, with ensemble model guidance showing high consistency in suppressing peaks below historical May averages around 31°C. Traders have priced the outcome at essentially 100 percent probability because official observations at primary stations like Changi will almost certainly align with these projections. Clearer skies or delayed rainfall would be required to push readings to 29°C or higher, an outcome models currently assign very low likelihood.
