Highest temperature in Guangzhou on August 5?

Platform comparison

Market context

Guangzhou’s **highest temperature** on 5 August will be set by the day’s peak reading at Baiyun International Airport, and the crowd is pricing a **0%** chance on the current board, which makes the consensus an outright reject of a heat spike. That leaves the market heavily tilted towards the more ordinary August range rather than an extreme upside print, with the most likely bands elsewhere on the board implied by forecasts clustering around the low-to-mid 30s Celsius rather than anything exceptional.[1][6][13]

Historically, August in Guangzhou is hot, humid and rain-prone, but not usually at the level needed to force a standout upside outcome; average August highs sit around 91°F/33°C, with monthly highs commonly quoted in the 89°F to 93°F range.[1][15][17] Several forecast sources for 5 August point to highs near 32°C to 35°C, with one detailed guide showing 35.2°C as the day’s high and another showing heavy rain at times, which is the key handicapper’s tension: cloud and showers can cap the top end, but a brief sunny window can still deliver a late-afternoon spike.[2][13] On that framing, the favourite is the mid-30s Celsius band, while the contrarian value is any outcome just above the consensus if precipitation arrives later than expected.

The main catalyst is timing, not theory: traders should watch the evolution of the local forecast through the day, especially rainfall intensity, thunderstorm risk and the hour-by-hour temperature curve, because the settlement is tied to the recorded maximum for the whole day at the airport station.[2][10][11] AccuWeather’s live radar model showed afternoon temperatures around 90°F to 94°F with precipitation and thunderstorm chances elevated, which supports the view that the range can be capped if convection develops early, but still leaves room for a brief peak before the rain arrives.[10][11]
