Recent forecasts from the Hong Kong Observatory and international numerical weather prediction models show a daytime maximum near 25°C on May 17, driven by a stable subtropical high-pressure system and lingering moisture that promotes cloud cover while limiting surface heating under a moist easterly flow. This setup deviates from typical late-May climatology, where clearer conditions often support highs of 28–31°C. Scattered showers or isolated thunderstorms could further cap peaks by 1–2°C depending on timing, tightening model consensus around the 25°C threshold. Trader positioning reflects this strong agreement, though unexpected clearing or shifts in the monsoon trough could push readings to 26°C or higher before the daily maximum is recorded.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 17 May '26.
The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (deg. C)" the specified date once information is finalized in the relevant "Daily Extract", available here: https://www.weather.gov.hk/en/cis/climat.htm
This market can not resolve to "Yes" until data for this date has been finalized.
The resolution source for this market measures temperatures in Celsius to one decimal place (eg, 9.1°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Recent forecasts from the Hong Kong Observatory and international numerical weather prediction models show a daytime maximum near 25°C on May 17, driven by a stable subtropical high-pressure system and lingering moisture that promotes cloud cover while limiting surface heating under a moist easterly flow.
