**Market-implied odds favor 27°C as the most likely daily maximum in Cape Town today, with 26°C a close second.** Clear skies, light easterly to southeasterly winds, and dry conditions under a stable high-pressure system support peak readings in the mid- to upper-20s Celsius, consistent with South African Weather Service guidance for warm conditions in the western Cape. Model consensus from sources including GFS and ECMWF shows afternoon temperatures climbing from morning lows near 13–15°C toward 24–28°C, with limited cloud cover and low humidity reducing evaporative cooling. Recent hourly observations near 22–23°C midday align with this trajectory, while minor model spread around wind strength and exact timing of the peak creates the tight clustering at 26–27°C. Traders appear to weigh the risk of a slightly cooler sea-breeze influence against the potential for stronger insolation under persistent clear conditions.

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.
