**Trader sentiment for the Cape Town maximum temperature on September 15 centers on 17–19°C, with 18°C holding the highest implied probability at 41.5%.** This reflects model consensus for a modest daily high under unsettled spring conditions rather than strong warming. Persistent cloud cover, showers or light rain, and northwesterly winds of 15–25 mph (roughly 7–11 m/s) are expected to limit solar heating and keep daytime maxima near or slightly below the September climatological average of ~18°C. Official and ensemble forecasts from sources such as WeatherBug, PredictWind, and global models show highs clustered around 16–18°C (61–64°F), with some runs reaching 63°F (~17°C) amid ongoing moisture and variable winds. Recent developments reinforce this range: stormy conditions and thunderstorms on September 13–14 have transitioned into a cooler, cloudier regime, suppressing temperatures ahead of the target date. Historical September extremes in Cape Town demonstrate that rain and strong onshore flow routinely cap highs several degrees below clear-sky potential, aligning with the market’s tight distribution around 17–19°C and lower odds on 20°C+ or sub-16°C outcomes. New model runs and observational updates on the morning of September 15 will be the key near-term catalyst.

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=fact
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.
