Recent numerical weather prediction ensembles for Wuhan indicate daytime maxima centered near 34–36 °C on July 13, with the spread arising mainly from variable convective timing under the East Asian summer monsoon and western Pacific subtropical high. Persistent high humidity and the potential for afternoon thundershowers or increased cloud cover can reduce peak temperatures by 1–2 °C through reduced insolation and evaporative cooling, while any delay in storm initiation or stronger subsidence allows readings to reach the upper 30s. Official guidance from regional models shows limited but non-negligible dispersion across this narrow band, consistent with mid-July climatology where average highs hover around 32–34 °C before seasonal peak heating intensifies later in the month. Traders are therefore pricing the highest probability on 35 °C, with meaningful shares distributed across 34–37 °C outcomes reflecting genuine forecast uncertainty two days before resolution.
