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 27 Aug '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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market can not resolve until the first data point for the following date has been published on the resolution source. 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.**Trader sentiment for Cape Town’s August 27 daily maximum temperature strongly favors warmer outcomes, with 25°C or higher at 71.5% implied probability.** This reflects current model consensus and recent observations indicating a mild winter day driven by northerly wind flow and limited cloud cover. Cape Town (33.9°S) experiences winter maximums averaging 16–18°C, but episodic warm spells occur when high pressure over the interior or the South Atlantic High promotes northerly advection of warmer continental air, often with light winds under 10 km/h. On August 26, the city recorded a maximum near 25°C, setting up similar conditions for the 27th. Official and private forecasts (SA Weather Service, ECMWF/GFS runs) project a daytime high of 24–26°C under partly cloudy skies, with peaks likely between 12:00–15:00 local time when solar heating is strongest and dew points remain low (~6–9°C). Key supporting factors include minimal precipitation risk (near 0%) and wind shifts from northerly to southwesterly that maintain mild conditions rather than introducing a strong cold front. Historical analogs for late August show occasional 23–27°C outliers under comparable synoptic setups, aligning with the market’s heavy weighting toward the upper bins. Updated guidance released in the past 24–48 hours has reinforced this trajectory, with little model spread expected before resolution. Upcoming official observations from Cape Town International Airport or the SA Weather Service will confirm the exact maximum, but current atmospheric conditions and forecast consistency underpin the elevated probabilities for 24°C+.
