Highest temperature in Singapore on July 27?

Platform comparison

Market context

Singapore’s highest temperature on 27 July will be set by the Singapore Changi Airport Station reading in the Wunderground daily history page, so the market is really about one afternoon spike rather than the day’s average weather. In an equatorial city where conditions are hot, humid and rainy year-round, the intraday range is often narrow, which makes the exact peak sensitive to cloud cover, showers and timing of any brief sun breaks.[2]

The current 0% crowd-implied probability for **YES** looks like a pricing artefact rather than a clear weather signal, because the market is already trading with a detailed outcome ladder and the leading bins are clustered around the low 30s Celsius. Polymarket’s public page currently shows **31°C** as the frontrunner at 35%, with **30°C** next at 32%, which is consistent with a market expecting a typical tropical daytime maximum rather than an extreme.[1] That kind of structure matters for reading probability: small forecast changes can shift the most likely bucket without implying a dramatic change in the underlying weather.[1]

For accessibility, the relevant regulatory frame is mostly about platform availability rather than the weather itself. A German user would need to consider the GlüStV gambling framework, because weather outcome markets can still be treated as gambling-like products depending on structure and local interpretation, while US users face the broader CFTC question of whether a contract is deemed an event contract within the agency’s reach. If the platform’s policy allows **no-KYC up to $1,500**, that generally means a smaller participant may access the market with lighter identity checks below that threshold, but the practical effect still depends on jurisdictional blocking, payment rails and any account-level limits.
