Official Central Weather Administration forecasts for Taipei on June 16 project a high near 29°C under mostly cloudy skies with occasional showers or thunderstorms, consistent with early summer Mei-yu influences and typical June humidity levels around 80%. Afternoon convection and cloud cover are the main variables that could limit peaks below this threshold or allow brief clearing to push readings toward 30–31°C if instability remains localized. Ensemble guidance shows modest spread due to steering patterns and moisture transport from the Pacific, with historical June maxima averaging 30–32°C but frequently tempered by precipitation. Traders appear to price modest upside potential from forecast revisions while weighting the current official guidance and seasonal wet pattern.
