**Trader consensus on the Polymarket heavily favors a 33°C daily maximum for Singapore on August 23, 2026 (61.5% implied probability), followed by 32°C (21%) and 34°C (15.5%).** This positioning reflects consistent official guidance from Singapore’s National Environment Agency (NEA) and Meteorological Service Singapore, which have projected daily maxima of 33–34°C across most days in the second half of August amid prevailing southwest monsoon conditions and below-average rainfall. Recent developments reinforce this outlook. The first half of August featured drier, occasionally windy weather that supported similar peaks, with the August 18 market resolving at exactly 33°C. Extended forecasts from sources such as timeanddate.com and AccuWeather indicate highs near 32–34°C (roughly 90–93°F) for August 22–23 under partly cloudy skies with limited afternoon convection, while NEA’s latest briefing notes short-duration thundery showers are possible but unlikely to suppress maxima below the 33°C range. Singapore’s equatorial climate produces narrow temperature variability, with historical August averages around 31–32°C and occasional peaks to 34°C when clearer conditions allow greater solar heating. Key near-term variables include any late adjustments to model guidance on cloud cover or wind patterns, as well as the precise official observation (typically the highest reading across the island’s network). With resolution only two days away, fresh NEA or MSS updates on convective activity will be the primary catalyst for any shifts in these market-implied odds.
