**Recent Singapore Meteorological Service outlooks and model guidance point to daily maximum temperatures of 33–34 °C on most days in the latter half of August 2026 under persistent southwest monsoon conditions.** Localized afternoon thundery showers and occasional fair, breezy periods are expected, with below-average rainfall overall. This pattern has already produced multiple days above 33 °C in August, including a peak of 34.9 °C at Pulau Ubin on 14 August. For 31 August specifically, ensemble forecasts show partly cloudy skies with a moderate storm risk in the afternoon; this convective activity typically caps peak readings but still allows surface temperatures to reach the low-to-mid 30s °C. Official guidance places the most probable daily maxima in the 33–34 °C range, with a smaller chance of 35 °C on clearer days. Nights remain warm and humid above 27 °C, consistent with the seasonal baseline. Market-implied probabilities—favoring 33 °C (52.5 %) and 32 °C (41.5 %)—align closely with this consensus. The narrow spread between these two outcomes reflects remaining uncertainty in the timing and coverage of showers versus clearer intervals, which can shift the daily high by 1–2 °C. Updated model runs and the next official briefing will be the primary near-term drivers of any further adjustments.
