Intro

This market tracks whether the peak daily temperature in Wuhan will reach exactly 30°C on May 30, 2026. On Polymarket, the leading outcome—a high of 30°C—stands at 35.0%, while a high of 29°C carries 28.5% probability. Resolution will be determined by historical weather data from Weather Underground, using readings from Wuhan Tianhe International Airport Station. Watch the official forecast and actual conditions as May 30, 2026 approaches to gauge whether seasonal warming patterns will push temperatures to the 30°C threshold.

Frequently asked questions

The market resolves on May 30, 2026, after the highest temperature in Wuhan on May 30 has been recorded and verified. Resolution depends on the official temperature reading from a designated meteorological source for Wuhan on that date. The outcome is determined by comparing the actual high temperature to the predefined thresholds embedded in each contract. Once the final temperature is confirmed, the winning outcome pays out in full and losing outcomes expire worthless. This binary structure ensures clear, objective settlement based on publicly available weather data.

Several factors could shift market odds before May 30, 2026. Major weather pattern changes—such as the arrival of cold fronts, monsoon activity, or high-pressure systems over central China—will influence trader expectations. Updated seasonal forecasts from meteorological agencies and real-time atmospheric data releases can trigger repricing. Broader climate anomalies, including El Niño or La Niña effects, may also impact regional temperatures. As May 30 approaches, increasingly accurate short-range forecasts will narrow uncertainty and drive final price convergence. Any unusual heat waves or cold snaps in the weeks prior could shift baseline assumptions about Wuhan's typical May temperatures.
