Current forecasts from the Hong Kong Observatory and supporting international models point to a daytime maximum of 27–28°C on May 18, driven by a subtropical ridge that maintains partly cloudy skies and limits intense solar heating under moderate easterly flow. This setup produces a modest cooling anomaly relative to the May climatological average of 28–30°C, positioning the 27°C outcome at 46 percent implied probability as the clear market favorite. Recent model runs show minimal divergence on these thresholds, with no significant moisture influx or wind shift expected to push readings higher. Traders are therefore concentrating capital around the 26–28°C range, reflecting the narrow uncertainty band in official guidance ahead of the day’s final observational data.

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.
