Current forecast models for Beijing show maximum temperatures on May 18 clustering around 25–26°C, shaped by a broad high-pressure ridge over northern China that favors clear to partly cloudy skies and moderate daytime heating. Subtle differences among ensemble runs from global prediction centers arise mainly from variations in simulated low-level moisture and boundary-layer mixing, which can shift the peak by 1–2°C depending on how much solar radiation reaches the surface. Mid-May climatology for the capital places average highs near 24°C, so the present pattern reflects modestly above-normal conditions without strong synoptic forcing for rapid warming or cooling. New model cycles expected within the next 24 hours will tighten the range and clarify whether the daily maximum settles at 25°C or edges higher.
