Recent typhoon Bavi's passage near northern Taiwan in mid-July has left lingering moisture and variable cloud cover, creating uncertainty in afternoon heating for Taipei on July 17. Central Weather Administration forecasts indicate daily highs near 35–36°C amid typical summer monsoon conditions, with high humidity supporting heat retention but scattered thunderstorms potentially capping peaks. Post-storm clearing could allow stronger insolation and urban heat island effects to push maxima toward 36–37°C, while persistent cloudiness or convective activity favors 34–35°C. Model consensus shows limited spread, with resolution hinging on short-term steering patterns and boundary-layer moisture that differentiate these closely matched outcomes.
