Recent PAGASA and numerical model guidance for Metro Manila show a trough of low pressure and southwest monsoon flow sustaining scattered thunderstorms through September 23, with forecast overnight lows centered near 24–26 °C. Cloud cover and rainfall can suppress radiative cooling and produce localized drops toward 24 °C, while clearer intervals or stronger southerly flow may hold minima closer to the seasonal 25–26 °C baseline. Ensemble spread remains modest, yet the market’s near-even odds between sub-22 °C and 31 °C+ outcomes reflect lingering uncertainty in timing of convective activity and exact wind-driven mixing ahead of the final 24-hour observational window.

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.
