**Wellington, New Zealand—widely recognized as the world's windiest city due to its exposure in the narrow Cook Strait—typically experiences peak September gusts shaped by frequent southerly and northwesterly flows, orographic channeling, and passing low-pressure systems.** As of mid-September 2026, observed gusts have reached around 60 mph (~97 km/h) on several days amid moderate breezes and showers, aligning with climatological patterns where spring transitions often produce gusts in the 50–65 mph (80–105 km/h) range without extreme events. Current forecasts from models like those referenced by MetService and Windy.app indicate ongoing moderate conditions with daily gusts mostly 25–37 mph (40–60 km/h) through the weekend and into late September, though additional fronts could generate stronger episodes. Trader consensus heavily favors the 90–101 km/h bin (71.5% implied probability) because historical September maxima at Wellington Aero and similar sites cluster in this band, reflecting typical synoptic activity rather than rare high-end storms. The modest 18% odds for 102 km/h or above account for the realistic chance of an intense system in the remaining weeks, while the low 3.3% probability for 89 km/h or below underscores the unlikelihood of an unusually calm month given the city's baseline wind regime. Resolution hinges on official peak gust measurements through September 30.

The resolution source for this market is the gust value in the wind group of NZWN's raw METAR/SPECI observations, encoded in knots (for example, "34020G45KT" denotes a 45-knot gust), as archived by the Iowa Environmental Mesonet (IEM) for station NZWN in network NF__ASOS ("New Zealand ASOS"). Gust speed is converted from knots using 1 kt = 1.852 km/h, rounded half-up to the nearest whole number. Because gusts are reported in whole knots, no observed gust converts to a value on a bracket boundary, so every observation maps to exactly one range.
The month's highest gust can be located via the IEM Data Calendar for NZWN: https://mesonet.agron.iastate.edu/sites/hist.phtml?network=NF__ASOS&year=2026&month=9&mode=monthly&station=NZWN. Each calendar day displays that day's peak gust inline; clicking a day's date opens the daily Summary for NF__ASOS, where the Peak Gust column in the NZWN (Wellington) row shows the day's maximum. Ensure station NZWN is selected, as the NF__ASOS network includes other New Zealand stations. Note that the IEM calendar and summary pages display gusts in mph; resolution is based on the knot value in the underlying raw METAR, which IEM archives alongside each parsed observation and which can be used to independently verify any value.
If any observations are missing or unavailable, this market will resolve to the range containing the highest gust reported during the resolution window. Should the IEM archive be unavailable or discontinued, this market will resolve based on the equivalent raw METAR/SPECI observations for NZWN from another credible archive or the original reporting authority.
