**Forecast models for June 15, 2026, point to a Beijing high near 29–31 °C, with the market’s tight clustering around 28–31 °C reflecting modest uncertainty in the precise peak.** Latest guidance from sources such as the BBC, UK Met Office, and timeanddate.com shows daytime maxima of 30–32 °C (86–90 °F) under a mix of clouds and thundershowers. These conditions are expected to limit insolation and evaporative cooling, keeping the reading just below or at the lower end of mid-June climatology (typically 30–32 °C). Key differentiating factors include the timing and coverage of any showers or thick cloud decks, which can suppress the maximum by 1–3 °C, versus brief sunny breaks that allow brief warming toward 31–32 °C. Surface humidity, boundary-layer mixing, and the strength of the prevailing easterly or southerly flow also modulate the outcome. Because the market resolves to the official reading at Beijing Capital International Airport, even small differences in local convective timing can shift the result between the closely priced 28–31 °C bins. Updated model runs and nowcasting on the morning of the 15th will be the main near-term drivers of further price movement.
