Traders see near-even odds between 36°C and 37°C maxima in Taipei on August 13 because short-range ensemble forecasts from agencies like the Central Weather Administration show peak afternoon temperatures clustered in the mid-30s under typical late-summer subtropical conditions. High humidity, urban heat-island effects, and variable cloud cover from afternoon convection introduce model spread of roughly 1–2°C, while steering patterns and any weak tropical disturbance could either enhance or suppress insolation. Historical August baselines near 33–34°C provide context, but recent stable high-pressure influence supports the slight edge toward the upper end of that range without pushing into extreme territory.
