Highest temperature in Singapore on July 1?

Platform comparison

Market context

The real-world event is the highest temperature recorded at Singapore Changi Airport on 1 July 2026, measured in degrees Celsius. Historical data shows July in Singapore is consistently hot and sticky, with average highs around 31°C and heat indices often exceeding 41°C due to high humidity [2]. Changi Airport’s climate is oppressive and overcast year-round, with temperatures rarely dipping below 24°C or rising above 32°C [1]. Given this stability, a 0% crowd-implied probability for any specific temperature range suggests the market may be mispricing the likelihood of extreme outliers, as July typically sees temperatures clustered tightly between 28°C and 32°C [3][5].

Traders should monitor daily weather bulletins from the Meteorological Services Singapore, which update historical records by the 10th of each month and may reveal anomalies in early July data [4]. Sudden thunderstorms or shifts in wind patterns—common in July due to 150mm of rainfall over three weeks—could temporarily suppress peak temperatures [2]. Additionally, watch for real-time observations from Wunderground, the official resolution source, as current readings show 28°C at 01:00 BST with hazy conditions and southerly winds at 6 mph [3]. Any deviation from the typical 31°C average, especially if linked to unseasonal cloud cover or rain, could shift the probability distribution significantly.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

How fast do sports winnings settle?

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
