Wellington, New Zealand, positioned at the exposed Cook Strait and influenced by the Roaring Forties westerlies, experiences its windiest conditions during spring. September climatology shows rising average wind speeds and frequent gusts exceeding 90 km/h at sites like the airport and Baring Head, driven by northerly and northwesterly flows compressed by local topography. Recent El Niño conditions have favored stronger westerly patterns, though September 2026 observations and forecasts through mid-month indicate no extreme events, with daily gusts mostly in the 60-80 km/h range and limited model consensus for late-month intensification. Trader pricing favoring a 90-101 km/h peak aligns with historical spring maxima and the absence of major low-pressure systems capable of pushing gusts above 102 km/h, while the low odds for sub-90 km/h reflect the season's baseline exposure.

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.
