Current forecasts from multiple models indicate Manila's overnight low on September 12 will likely reach 25–26°C, aligning with the tight market clustering around those outcomes. Persistent cloud cover, high humidity near 90% at night, and light variable winds limit radiative cooling in this tropical setting, keeping the diurnal range narrow. Historical September averages show nighttime lows near 25–26°C, with minimal deviation absent strong monsoon surges or clear-sky outbreaks. Recent observations confirm overcast conditions and scattered showers, further moderating temperature drops while official monitoring highlights stable steering patterns that reduce variability in the final hours.

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.
