Hong Kong Observatory's latest forecasts, drawing from ECMWF and GFS ensemble models, point to a high of 25-27°C on March 22 under mostly fine skies with light southerly winds, fueling the razor-thin trader odds atop 25°C (26.5%) and 27°C or higher (26.0%). Recent dissipation of a northeasterly monsoon has allowed warmer maritime air to dominate, elevating baselines from last week's cooler 20-22°C readings, while historical March maxima average 23.5°C. Differentiation hinges on cloud cover and insolation: full sunshine could push 27°C+ via peak solar heating, but scattered showers—20% modeled probability—might cap at 24-25°C by reducing radiative forcing, with 24°C (23%) reflecting conservative trader hedging amid model spread.

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.
