Current forecasts from Taiwan’s Central Weather Administration and supporting regional models place Taipei’s daily maximum temperature at 31°C on May 17 under a stable subtropical high-pressure regime. Light easterly flow, minimal cloud cover, and typical pre-Meiyu early-season conditions have produced this consistent projection across official guidance, supporting the market’s near-100% implied probability for the 31°C outcome. Historical May climatology for northern Taiwan shows average highs near 28–30°C, so today’s setup aligns with expected warming before the seasonal monsoon front arrives. An unexpected surge in afternoon convection or a subtle shift in steering winds could still nudge the peak to 30°C or 32°C, though current model consensus and observational trends indicate low likelihood of such deviations before resolution.
