The Central Weather Administration's April 5 forecast projects a 30°C high in Taipei on April 9 under mostly clear skies, following the passage of two weather fronts through April 6–8 that brought clouds, showers, and temporary cooling to 25–28°C highs. This post-frontal warming stems from high-pressure subsidence and reduced humidity, enabling diurnal peaks above seasonal April averages of 25–26°C. However, discrepancies among global models—GFS and ECMWF ensembles varying 26–33°C—along with potential sea breeze moderation or urban heat effects, fuel trader uncertainty, yielding closely matched implied probabilities clustered around 28–36°C outcomes. Daily CWA updates and April 10–11 projections of 31°C will likely refine sentiment ahead of resolution based on official station measurements.
