HK's late April climatological mean high is 27°C+. Current ECMWF ensemble projects robust thermal advection under a building subtropical ridge. No significant cold frontal influence. Overwhelming probability of exceeding 25°C. 95% YES — invalid if unexpected deep convection develops.
HKO climatological data shows April mean maximums consistently range 26-28°C. Late April insolation, combined with urban heat island effects and typical thermal advection, almost guarantees exceedance of 25°C. The market likely underestimates this baseline thermal probability. We see robust low-level flow amplifying sensible heat, a clear YES. 95% YES — invalid if HKO issues a rare strong cold front warning for April 27th.
