Highest temperature in Singapore on July 8?

Platform comparison

Market context

On 8 July 2026, Singapore Changi Airport will experience its peak daytime temperature, a single metric that determines whether the market resolves to the 31°C range or higher. Current observations show thundery showers with temperatures at 30°C by 02:00 BST, while the forecast predicts a high of 88°F (31°C) with morning rain and brief late-night showers [1][3]. The crowd-implied 0% probability for the 31°C range suggests traders believe conditions will remain too wet or cool to breach this threshold, despite the forecasted peak aligning exactly with that value.

Historically, July highs at Changi Airport typically span 30°C to 34°C, with 31°C and 32°C being the most frequent single-day peaks [6]. Over the year, temperatures rarely exceed 92°F (33°C) or drop below 74°F (23°C), making 31°C a statistically common outcome rather than an outlier [4]. The current 0% probability appears misaligned with this baseline, as sustained cloud cover or rain would need to be unusually persistent to suppress temperatures below 31°C in mid-July, a period known for consistent heat.

Traders should monitor real-time updates from Wunderground, the official resolution source, for any shifts in cloud density or rainfall intensity that could cap the peak temperature [7]. A sudden increase in afternoon thunderstorm activity, as hinted in the forecast for 7–9 July, could be the critical catalyst preventing the 31°C breach [1]. No official weather advisories have been issued yet, but the presence of morning rain and potential late showers remains the primary dependency for this market’s outcome.

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.

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.

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?

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.
