Current forecasts from PAGASA and global models indicate Manila's overnight low on September 21 will likely fall in the 25–26°C range, driven by the southwest monsoon (habagat) delivering persistent cloud cover, scattered showers, and high humidity that moderates radiative cooling. This setup compresses the diurnal temperature range in Manila's tropical climate, where typical September minima hover near 25°C. Strengthening El Niño conditions favor broader warming trends but exert limited influence over this 48-hour window compared with monsoon dynamics. Trader sentiment remains split near 45–46% between sub-21°C and 31°C+ outcomes because exact minima depend on localized thunderstorm timing and cloud breaks, though official guidance shows low probability of extremes outside the mid-20s. Updated model runs and PAGASA briefings through September 20 will refine resolution thresholds.

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.
