Highest temperature in Singapore on July 1?

Platform comparison

Market context

The real-world event is the daily peak temperature recorded at Singapore Changi Airport on 1 July 2026, measured in degrees Celsius. Historical data shows July highs in Singapore consistently hover around 31°C (88°F), rarely dipping below 29°C (85°F) or exceeding 33°C (91°F)[2]. Polymarket traders currently assign a 99% probability to the 32°C range for this specific date, with 33°C as the only distant alternative[1]. This overwhelming market consensus aligns with climatological norms during the ongoing Southwest Monsoon, making the crowd-implied 0% probability for any outcome outside the 31–33°C band appear statistically sound rather than speculative.

Traders should monitor the official Wunderground daily report for Changi Airport, which settles the market at 12:00 UTC on 1 July 2026, and watch for any sudden shifts in monsoon intensity or cloud cover that could depress temperatures below the 31°C threshold[8]. While global heat records have been broken recently, with July 2024 marking the warmest month in 120,000 years, Singapore’s tropical climate typically buffers against extreme spikes, keeping daily highs stable[4]. No major weather announcements are expected to alter this trajectory, as the Southwest Monsoon pattern remains the dominant driver for July temperatures in the region, ensuring the resolution source will likely confirm the 32°C frontrunner.

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.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
