Highest temperature in Cape Town on August 3?

Platform comparison

Market context

Cape Town’s August temperature profile has not shifted much in the last 24–48 hours: the city is still sitting in its winter pattern, with forecast daily highs clustered around 16–18°C and frequent cloud or rain risk rather than heat. Recent monthly guidance puts August averages near 17°C, with overnight lows around 8–10°C, which is a long way from the kind of conditions needed to threaten the upper bands in this market.[1][3][15]

That makes the current 0% YES pricing easy to read: it is consistent with a typical Cape winter, but it also assumes no unusual warm spell at Cape Town International Airport. Comparable August climatology shows highs usually topping out in the low-to-mid teens Celsius, with some sources allowing occasional peaks closer to 21–22°C on warmer days, so the main question is whether a brief, localised spike shows up before the settlement window closes.[5][10][17] Because the market resolves to the *highest* temperature recorded on the day, a single sunny afternoon matters more than the average weather profile.[1]

Traders should watch the South African winter weather setup over the next day, especially any weakening of cloud cover, rainfall, or coastal wind, since those are the factors that can suppress the afternoon peak at the airport station. The key dependency is the official history entry for Cape Town International Airport on Wunderground, which will capture the day’s maximum rather than a forecast estimate, so late-morning to mid-afternoon conditions are the critical period for any upside surprise.[1]
