Official measurements from the Hong Kong Observatory recorded a daily maximum of 27°C on May 15, establishing a firm baseline that aligns with mid-May climatological norms and current sea-surface temperatures in the South China Sea. This verified observation anchors near-certain trader consensus on the 27°C outcome, as official station data resolve the market directly without reliance on forecasts or models. Minor adjustments could arise only from rare post-processing revisions to the raw readings or station-specific averaging methods, though historical patterns show such changes rarely shift the reported peak by more than 1°C.

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.
