Highest temperature in Singapore on August 6?

Platform comparison

Market context

Polymarket is pricing this contract at 0% YES, so the market is effectively saying there is no live bid for the highest temperature at Singapore Changi Airport on 6 August 2026 landing in the YES outcome. The contract settles against the daily high reported by Wunderground for Singapore Changi Airport Station, with USDC-margined positions on Polygon represented by conditional tokens, so the practical question is not whether Singapore is hot in August, but where the day’s peak observation falls relative to the market’s listed temperature bands.

Seasonal context points towards consistently warm conditions rather than a clean outlier. August in Singapore typically brings daily highs around 30°C–31°C, with forecast ranges from the mid-80s to high-80s °F across several weather services, while current observation data for Singapore shows temperatures already in the high 20s to low 30s Celsius this morning. Broad August climatology also suggests humidity, cloud cover and passing showers can cap the maximum even when the day feels oppressive, which matters because this market resolves on the single highest station reading rather than the “feels like” value.

For traders, the key catalysts are the day’s weather evolution and the official update sequence on the resolution source. A hotter-than-expected midday burst, delayed showers, or a clear-sky afternoon could lift the final peak, while cloud build-up or convective rain would push the reading lower; once Wunderground has published the first datapoint for the following date, later changes no longer count under the market rules. Because settlement depends on the Changi Airport station specifically, live Singapore-wide forecasts are only a guide, and the relevant watchlist is the station’s observed max rather than the city average.
