Highest temperature in Shanghai on July 24?

Platform comparison

Market context

Shanghai’s airport temperature on 24 July will be driven by the day’s *actual* peak at Pudong, not the citywide feel, so the key input is whether the site gets a clear, dry heating window before cloud or showers build. Early- to mid-30s Celsius is the normal July regime in Shanghai, with the month typically hot, humid and rain-prone; that leaves a fairly broad but still weather-constrained range for the day’s maximum. Short-run forecasts for Shanghai around this period point to highs near 32–35°C, with a mix of sunshine, humidity and intermittent showers, which is the right operating band for a programme that maps the market to temperature buckets rather than a single number.

For a power-user, the cleanest way to approach this is to treat the market as a daily max-temperature feed from Wunderground and wire alerts around threshold crossings rather than headlines. The current 0% YES implied probability suggests the crowd is not pricing the target range, but that can change quickly if morning cloud breaks or convection is delayed; at an airport station, sea-breeze effects, precipitation timing and runway-side cloud cover can all move the high by a few degrees. The useful catalysts are the morning forecast updates, any thunderstorm timing shifts, and whether the forecasted afternoon showers arrive early enough to cap the maximum; nearby forecasts for Pudong already show a warm, humid day with some shower risk, so traders watching conditional orders or bot triggers would typically key off revised hourly temperature and precipitation probabilities through the late morning UTC window.
