Highest temperature in Cape Town on August 3?

Platform comparison

Market context

Cape Town International Airport’s highest temperature on 3 August will be read from a single-day history page on Wunderground, so the key variable is the day’s actual peak at the airport station rather than a citywide estimate. For a programmatic workflow, that means polling the source close to settlement, extracting the daily maximum in Celsius, and mapping it to the market’s fixed temperature bands rather than trying to forecast the exact reading.

The crowd’s 0% YES implies the current price is effectively assigning no weight to an outcome in the market’s selected band, which is unusual for Cape Town in August given the climatology. External weather guides cluster August daytime highs around 16–18°C, with some sources putting typical highs nearer 17°C and average lows around 8–11°C, alongside winter rain and occasional clearer, warmer spells[1][3][4][15][17]. That makes the distribution broad enough that a one-day airport maximum can still land materially above or below the seasonal mean depending on cloud cover, wind and frontal passage.

The main catalysts are the synoptic setup over the south-western Cape, any cold front timing, and whether morning cloud breaks early enough for inland warming before the afternoon maximum. Cape Town’s August pattern is typically mixed, with rainy, cloudy days interspersed with milder, sunnier intervals[3][17]; traders using conditional orders or bot scripts would usually monitor the latest forecast refreshes against the Wunderground history output, then size around the temperature bucket most likely to catch the recorded peak.
