Highest temperature in Singapore on July 27?

Platform comparison

Market context

Singapore Changi Airport’s highest temperature on 27 July will be set by the day’s actual peak reading at the station, with the market resolving against the Wunderground history page for that date. The crowd is currently leaning to a fairly tight band around the low 30s Celsius, with **31°C** leading at 35% and **30°C** next at 32%, which implies traders expect a warm but not exceptional afternoon rather than a breakout heat spike.[1]

That profile fits Singapore’s late-July climatology: the south-west monsoon period still brings frequent cloud and rain, but daytime highs in the city-state commonly reach around **31°C**, with average temperatures nearer **27°C** and a high chance of cloud cover and showers.[3][5] In historical terms, a 0% yes-style reading on a single temperature outcome would be less surprising if the market were asking for an exact number, because Singapore’s daily peak is usually compressed into a narrow range rather than swinging sharply from day to day.[3][4]

The main trader catalysts are the morning-to-afternoon weather sequence at Changi and whether convective rain or persistent cloud limits heating before the settlement window closes at 12:00 UTC, which is 20:00 local time in Singapore. The key dependency is the airport station’s own observation, not citywide conditions, so a brief thunderstorm, sea breeze shift or delayed clearing can be enough to keep the maximum at 30°C rather than 31°C or higher.[1][2]

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?

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.
