**Wellington, New Zealand—the world’s windiest city due to its position in the Roaring Forties and Cook Strait’s funneling effect—sees highly variable September peak gusts shaped by springtime strengthening of westerly and northwesterly flows.** Historical data show daily maximum gusts averaging around 65 km/h annually at key stations like Wellington Aero, with spring maxima frequently exceeding 100–130 km/h during northerly events, though individual monthly peaks depend on the passage of intense low-pressure systems or fronts. The balanced market-implied odds across the three bins reflect this inherent uncertainty: weaker or fewer synoptic setups could keep the peak at or below 89 km/h, typical seasonal activity often lands in the 90–101 km/h range, and a single strong event or persistent gradient can push gusts to 102 km/h or higher, as seen in past spring analogs reaching 150+ km/h. Forecasters monitor pressure differences across the strait and model consensus on upcoming systems, with new runs likely to shift probabilities as September begins.

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.
