Current forecasts for Manila on September 19 indicate overnight lows near 25–26°C under typical southwest monsoon conditions with high humidity, scattered thunderstorms, and persistent cloud cover from the ITCZ. These factors suppress radiational cooling by trapping heat and limiting clear-sky temperature drops, aligning with historical September averages of 25–26°C. Trader sentiment remains split between sub-21°C and 31°C+ extremes because model runs show sensitivity to variables like exact cloud thickness, wind speed at the surface, and any localized convective outbreaks that could briefly alter the diurnal range. Upcoming PAGASA updates and refined model ensembles in the next 48 hours will likely tighten the implied probability distribution around the mid-20s range.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=rpll
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
