Wellington experiences variable spring weather as autumn transitions in the Southern Hemisphere. On April 18, 2026, this market asks whether the city's daily high will reach 21°C or above. Current odds of just 1% for YES reflect market expectations that Wellington will not reach this temperature threshold on that specific date. The resolution uses official meteorological data from a recognized weather station in Wellington to determine the actual maximum temperature for the day. A reading of 21°C or higher triggers a YES resolution; any lower reading resolves NO. At these odds, market participants are pricing in a very high probability that temperatures will remain below 21°C, possibly due to seasonal patterns, historical climate data for April, or short-term weather forecasts available at market creation. The market has generated significant trading activity with $2,036 in 24-hour volume and $1,601 in active liquidity, indicating substantial trader interest despite the overwhelming consensus suggesting a NO outcome. Odds movements will likely shift based on updated weather forecasts and seasonal climate models as April 18 approaches, providing opportunities for traders to adjust positions based on new meteorological information.
