Highest temperature in Singapore on July 27?

Platform comparison

Market context

Singapore’s daytime heat is normally capped by heavy humidity and frequent cloud build-up, so the distribution for a one-day high is usually tight rather than extreme. July is still warm by local standards, with typical daytime maxima around 34°C and average lows near 25°C, while rain and convection often interrupt the hottest part of the day.[3][4]

That is why a 0% implied price for any higher outcome should be read cautiously: Singapore regularly sits in the low-30s, and the current market leader is 31°C at 35%, with 30°C close behind at 32%.[1] Comparable July climatology suggests the ceiling is often reached in the low-to-mid 30s rather than pushed much higher, but the airport station can still print a hot afternoon if cloud cover is delayed or rainfall misses the late-morning window.[3]

The main things to watch before the settlement cut-off are morning thunderstorms, sustained cloud cover, and any change in forecasted rain timing around the warmest hours. Singapore’s July rain often peaks around early afternoon, which can blunt the high if showers arrive early, while a longer dry spell lets temperatures climb towards the upper end of the usual range.[3] If the day starts clear and the heat builds before convection triggers, the top reading at Changi can move quickly within a narrow band.

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.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
