Forecast models from agencies including the Met Office and local observations indicate a typical overnight minimum near 25–27°C for Kuala Lumpur on August 31, consistent with the market’s tightly grouped leading outcomes. In this equatorial setting, nighttime radiative cooling is limited by high humidity (often >80%), persistent cloud cover from convective showers, and light variable winds that reduce heat loss. Recent August conditions show slightly above-normal temperatures and frequent light rain, which suppress minima by trapping heat and moisture near the surface. The narrow spread among 25–27°C reflects modest uncertainty in exact cloud timing and urban heat retention rather than any large-scale shift, with resolution hinging on the lowest hourly reading at official stations.
