Short-range forecasts from Taiwan's Central Weather Administration and global models point to peak temperatures near 31–32°C in Taipei on June 17, consistent with early-summer climatology under the influence of the subtropical ridge. High atmospheric moisture and the typical diurnal cycle of convective showers—often developing in the afternoon—introduce substantial uncertainty, as earlier or heavier cloud cover and rainfall could cap maxima at 29–30°C while clearer intervals might allow brief spikes to 33°C. Urban heat-island effects and sea-breeze interactions add local variability, keeping trader-implied probabilities tightly clustered across the 29–33°C range with no dominant outcome. Updated model runs over the next 48 hours will likely refine these thresholds before resolution.
