Official forecasts from Taiwan's Central Weather Administration project a daytime high of 34°C in Taipei on August 18 amid partly cloudy skies and occasional showers, directly supporting the market's leading 35°C (44.5%) and 34°C (27.5%) outcomes. Late-summer subtropical conditions in northern Taiwan typically deliver highs of 32–35°C, amplified by the urban heat island effect and high humidity, though afternoon convection often triggers showers that limit further intensification. Recent days saw peaks reaching 36–37°C under clearer, hotter patterns, but the shift toward increased moisture has moderated model consensus for tomorrow. Traders weigh these variables against historical August averages near 33–34°C, with resolution depending on the precise observed maximum at official stations.
