**Observed maximum temperatures at Cape Town stations reached 18.9°C on September 12, 2026, driving the market's near-certain 19°C outcome.** Official meteorological data recorded a daily high of 18.9°C under overcast skies with light winds and minimal precipitation, consistent with multiple forecast models that converged on an 18–19°C peak during the afternoon. This aligns with the current late-evening readings near 16°C after the daytime maximum, confirming the daily high. The strong consensus reflects real-time surface observations from authoritative monitoring networks rather than projections. A shift would require an unreported station measurement exceeding 19.5°C or a significant revision in official records, both improbable given the consistency across sources and the day's stable synoptic conditions.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Cape Town International Airport Station in degrees Celsius on 12 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=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.**Observed maximum temperatures at Cape Town stations reached 18.9°C on September 12, 2026, driving the market's near-certain 19°C outcome.** Official meteorological data recorded a daily high of 18.9°C under overcast skies with light winds and minimal precipitation, consistent with multiple forecast models that converged on an 18–19°C peak during the afternoon.
