About this Market

Singapore’s equatorial location and Southwest Monsoon conditions keep daily highs tightly clustered near 30–32°C, with afternoon thundery showers frequently capping temperatures through increased cloud cover and evaporative cooling. Current forecasts from regional models show modest variability around these values for July 21, influenced by the timing and coverage of convection as well as lingering El Niño-driven warmth that has elevated baseline readings this season. The near-even market odds between 30°C and 32°C reflect this narrow uncertainty band, where small shifts in shower onset or wind patterns could determine whether the official observation peaks at the lower or upper end of the range. Historical July maxima average near 31°C, underscoring how routine monsoon dynamics dominate over longer-term trends for this short-term resolution.
