Recent forecast consensus from models including GFS and Met Office data positions a daytime maximum of 32–33°C as the most probable outcome for Singapore on September 4, aligning with the market's strong preference for 33°C. Equatorial conditions near the intertropical convergence zone typically produce stable highs in this range during early September, with limited day-to-day variability driven by southeasterly winds and moderate humidity levels of 60–85%. Official observations and ensemble runs show no significant warming trend or anomalous steering patterns that would push readings to 34°C or higher, while historical baselines confirm September averages near 31°C. Updated model guidance expected later today could refine peak timing and any localized urban heat effects before market resolution.

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=wsss
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.
