Forecasts from Singapore's Meteorological Service indicate afternoon thundery showers on September 22 under ongoing Southwest Monsoon conditions, with southeasterly to southwesterly winds favoring localized convection that often caps daytime highs. Official outlooks project daily maxima of 33–34°C on most days in late September, occasionally reaching 35°C, yet recent model guidance and historical patterns during similar monsoon phases point to peaks clustering around 32–33°C when showers develop by midday. Recent dry spells earlier in the month have elevated baseline warmth, but increased shower activity in the second fortnight introduces cooling and cloud cover that narrows the range. Market-implied odds reflect this balance, with traders weighting the moderating influence of expected precipitation against the potential for clearer intervals to push readings higher. Updated NEA briefings and radar trends ahead of the date remain key variables.

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.
