Polymarket
This market tracks whether the lowest temperature recorded at Tokyo Haneda Airport on May 29, 2026 will reach 22°C. On Polymarket, the probability that the low will be 22°C stands at 81.0%. Resolution will be determined by historical temperature data from Weather Underground, which maintains detailed records for Tokyo's airport station. Watch the weather forecast updates in the days leading up to May 29, 2026, as seasonal patterns and any approaching weather systems could shift expectations for the day's minimum temperature.
The market resolves on May 29, 2026, after the lowest temperature reading for May 29 in Tokyo is recorded and verified. Resolution depends on official meteorological data from Japan's weather authorities, which measure minimum daily temperature according to standard protocols. Once the actual low is confirmed, the corresponding outcome contract settles to 1 cent and all other outcomes settle to 0. Traders should monitor official announcements and data releases to understand the exact timing and source of the final temperature figure.
Major weather pattern shifts, seasonal forecasts, and atmospheric pressure systems over East Asia can significantly move odds. Updates from the Japan Meteorological Agency, tropical cyclone activity, and upper-level wind anomalies in late May will influence trader expectations. Historical May temperature data and climate oscillations such as the East Asian summer monsoon onset timing may also drive repricing. Real-time weather model runs and satellite imagery closer to May 29 will likely trigger sharp odds adjustments as the event date approaches and uncertainty narrows.
