Trader consensus on Singapore’s June 16 maximum temperature clusters tightly around 30–31 °C, reflecting modest forecast spread in regional models amid typical early-summer conditions. Singapore’s equatorial climate produces small day-to-day variability, with climatological June highs near 31 °C; afternoon convective showers driven by sea-breeze convergence and the southwest monsoon often cap peak readings by limiting insolation. Current ensemble guidance shows slight differences in predicted cloud cover and timing of showers, enough to separate a 30 °C outcome from 31 °C but insufficient to push probabilities toward 32 °C or lower values. Updated runs from global models will refine these thresholds before market resolution.
