This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Ninoy Aquino International Airport Station in degrees Celsius on 5 Sep '26. The resolution source for this market will be information from NOAA, specifically the highest 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.
Persistent southwest monsoon (habagat) activity is the main driver keeping trader focus on 28–30°C outcomes for Manila’s September 5 high. Official PAGASA guidance and multiple forecast models show widespread cloud cover, scattered to occasional heavy rain, and southwest winds across Metro Manila, which reduce solar insolation and cap daytime warming. Recent advisories highlight 50–100 mm rainfall potential through the period, consistent with the climatological peak of the rainy season when mean highs hover near 30°C but frequently fall several degrees under monsoon conditions. Updated model runs through early September reinforce this pattern with minimal day-to-day variability, supporting the current market distribution favoring the middle of the observed range over extremes.
