Market context

On 10 June 2026, the Hong Kong Observatory will record the day's highest temperature in degrees Celsius. This market settles on that single reading, rounded to one decimal place, with traders selecting from predefined temperature ranges. The settlement window closes at midday UTC on that date, though the Observatory typically publishes daily climate data within 24 hours of observation.

Hong Kong's June temperatures are shaped by the onset of the southwest monsoon and increasing humidity ahead of the summer peak. Historical data shows June daily maxima typically range between 28°C and 32°C, with occasional readings exceeding 33°C during heat waves. The 0% implied probability across the current market suggests traders are either awaiting range options to be specified or treating this as a placeholder contract pending fuller market development. No comparable sportsbook or traditional betting market exists for weather specifics of this granularity, making cross-platform odds comparison impossible.

The key dependency is the Hong Kong Observatory's publication schedule and data quality. Tropical cyclone activity, which peaks from July onwards, is unlikely to influence early June conditions significantly. Traders should monitor the Observatory's daily climate extraction portal for any publication delays or methodology changes that might affect settlement timing. The contract cannot resolve until official data appears in the "Daily Extract" section, creating potential settlement lag if the Observatory experiences operational disruptions or data verification delays.
