Will the highest temperature in Shanghai be 28°C on April 9?

“Multiple forecast models (GFS/ECMWF) cluster around 26-28°C for April 9, placing 28°C squarely within the central forecast range. The statistical models imply a 26-28°C cluster, meaning 28°C is not an outlier but a modal outcome within current projections.. AccuWeather's extended outlook projects a high of 88°F (31°C) on April 9 under mostly sunny conditions with southerly flows from the South China Sea. Even if this overshoots by 2-3°C (within typical forecast error of ±2°C), the result lands right at 28°C..”

“The market resolves to EXACTLY 28°C (or a range containing 28°C) — this is a precision target, not a directional bet. Even if the bull is correct that forecasts cluster around 26-28°C, the temperature must land in a specific narrow band. With a ±2°C forecast uncertainty spread across a continuous distribution, the probability of hitting any single 1°C bin is roughly 20-25% at best, and that's assuming the forecast mean is centered exactly on 28°C.. The bull's claim that 'GFS/ECMWF cluster around 26-28°C placing 28°C squarely within the central forecast range' is misleading. A cluster around 26-28°C means the MODE is likely 26-27°C, not 28°C. If the central tendency is 27°C with ±2°C spread, the probability of landing in the 28°C bin specifically is well below 25%, not a 'modal outcome.'.”
