Highest temperature in Guangzhou on August 10?

Platform comparison

Market context

Guangzhou’s highest temperature on 10 August will be set by the **Daily Observations** entries for Guangzhou Baiyun International Airport on Weather Underground, so the practical trigger for a yes/no-style outcome is the intraday maximum that actually appears there, not the broader day-high summary. At 8:00 UTC, Weather Underground was showing 97°F/83°F at Guangzhou, while AccuWeather had an hourly forecast of **100°F** for the day and **86°F** overnight, which is consistent with a hot, late-summer setup rather than a marginal temperature call.[14][13]

For context, August in Guangzhou is normally very warm and humid, with climatology around the low 30s Celsius and a tendency for daily highs to cluster near 33°C, so outcomes in the upper 30s need stronger-than-normal heating or limited cloud/rain to verify. Recent history and nearby guidance point the same way: WeatherAPI lists August averages around **33°C / 27°C**, China Discovery gives an August high near **33°C**, and WorldWeatherOnline shows recent 10 August highs reaching **37°C** or **36°C** in some years.[3][16][7]

A programmatic trader would monitor the Weather Underground history page for fresh observations and any backfilled revisions before settlement, because the market resolves from the recorded maximum in the observation table and revisions remain relevant until the next day’s first datapoint appears. The main catalysts are the actual hourly station readings at Baiyun Airport, plus any short-term change in cloud cover or rain; AccuWeather’s current forecast of **hot with clouds and sun** and only a **5%** precipitation chance implies limited convective cooling, which is the sort of input a bot can ingest directly into a temperature-range model.[10][13][8]
