Hong Kong Observatory observations confirm a maximum temperature of 27°C recorded today, April 30, 2026, driving trader consensus to 100% implied probability for 25°C or higher, as morning readings climbed from around 20°C amid mainly cloudy conditions with moderate easterly winds. This aligns with April's climatological average highs near 26°C and recent patterns of above-normal heat, including 30.2°C on April 16 and seasonal forecasts from the Observatory predicting normal to above-normal temperatures influenced by a weakening northeast monsoon. Model consensus in the latest 9-day outlook projected 22–25°C today under low rain probability (PSR low), but actual data exceeded expectations. Realistic challenges, such as an unexpected squally shower inducing evaporative cooling before day's end, are improbable given current stability and low thunderstorm risk.

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.
