Highest temperature in Hong Kong on June 29?

Platform comparison

Market context

The underlying real-world event is the peak daily temperature recorded by the Hong Kong Observatory on 29 June 2026, measured in degrees Celsius to one decimal place. Historical data frames the current 0% crowd-implied probability for a specific low range as highly improbable given the seasonal forecast. The Hong Kong Observatory predicts above-normal temperatures for June to August 2026, with 2026 potentially ranking among the top ten hottest years on record for the city[1][7]. Recent records show Hong Kong hit 34.6°C on its hottest day of the year so far in June 2026, while the New Territories recently faced warnings of extreme heat reaching 37°C[2][5]. The 2023 summer already set a benchmark with a mean temperature of 29.7°C, suggesting that any low-range outcome contradicts the established trend of abnormally high heat[4][9].

Traders should monitor the finalisation of the "Daily Extract" data from the Hong Kong Observatory, which is the sole resolution source for this market[1]. Key catalysts include the official seasonal forecast updates and any extreme heat warnings issued for late June, as these directly influence the maximum temperature range[2]. The market remains inaccessible until the specific date data is published, creating a dependency on the Observatory’s schedule for the "Absolute Daily Max" figure[1]. While regulatory frameworks like the German GlüStV and US CFTC reach impose compliance standards, the "no-KYC up to $1,500" provision allows immediate accessibility for smaller participants without identity verification, provided the platform adheres to local tax and KYC rules. This specific market’s accessibility is thus broadened for retail traders who fall within the monetary threshold, bypassing traditional barriers while remaining subject to overarching regulatory oversight.
