Trader consensus on Polymarket favors a high of 32°C (42.5%) or 33°C (29.5%) for Singapore on March 28, driven by the latest forecasts from the Meteorological Service Singapore (MSS) indicating peak temperatures in that range amid persistent inter-monsoon conditions. Singapore's equatorial climate delivers consistent daily highs of 30–34°C with high humidity amplifying heat index values, but recent observational data shows afternoon sea breezes and isolated thunderstorms capping extremes, as seen in the past week's averages around 32°C. Model ensembles from global systems like ECMWF and GFS align on minimal cooling influences, though urban heat island effects in the city-state could nudge toward 33°C. Uncertainty stems from potential convective activity; watch MSS's morning update for refined hourly guidance before resolution based on Changi Airport observations.
