توقع: Highest temperature in Guangzhou on August 4?

Platform comparison

Market context

Guangzhou Baiyun Airport’s **4 August high** looks set to come from a hot, humid summer pattern rather than an outlier spike. Forecasts for Guangzhou on 4 August cluster around the low 30s Celsius, with official guidance from the Guangdong meteorological service showing **25–32°C** for Guangzhou and separate daily forecasts pointing to around **33°C** or **90°F** in the city[2][3][15]. AccuWeather’s August outlook for Guangzhou also places typical daily highs in the **89–93°F** range, which is broadly consistent with a settled high-20s to low-30s Celsius result[1].

The historical frame suggests that a winning band above the current crowd-implied **0% YES** is not especially demanding in this climate. August in Guangzhou is normally one of the hottest, stickiest periods of the year, with average highs around **91°F** and repeated guidance that the month sits roughly in a **26–33°C** to **28–34°C** range[1][7][14][17]. Recent station-level observation data from Guangzhou/Baiyun Airport also shows temperatures already around **30°C** with high humidity, which matters because warm, moist air can keep daytime readings elevated even when showers are in the forecast[8].

For traders, the main catalysts are the day’s evolving rain and cloud cover, plus whether any thunderstorm line passes over the airport during the warmest afternoon hours. Guangzhou forecasts for 4 August call for **moderate rain**, **showers**, or **thundery showers** at different outlets, and rain timing is the key dependency because cloud cover can cap the daily maximum even when the broader air mass is hot[2][8][15]. The market will settle on the **highest temperature recorded at Guangzhou Baiyun International Airport Station** on the day, so late-morning heating, afternoon convection, and any airport-specific observation update from Wunderground are the variables that matter most[market description].
