Recent Central Weather Administration forecasts for Taipei indicate a daytime high of 27–34°C on August 29 under mostly cloudy skies with afternoon thundershowers, driven by lingering moisture from Typhoon No. 18's outer circulation and a broad low-pressure environment favoring southwest to southerly flow. These conditions promote cloud cover and convective activity that typically suppress peak temperatures below clear-sky potential, aligning with climatological August averages near 32°C while introducing uncertainty from model spreads on storm timing and intensity. International outlooks vary slightly (33–35°C), but official guidance and recent model consensus emphasize the moderating effect of precipitation, positioning 34–35°C as the most probable range in trader assessments ahead of final observational data.
