Wellington, New Zealand, experiences peak September gusts shaped by its location in the Roaring Forties and funneling through Cook Strait, where northerly events often produce the strongest readings at exposed sites like Wellington Aero. Historical records show spring maxima frequently reaching 100–140 km/h, with gusts exceeding 96 km/h occurring dozens of times per season on average. A developing super El Niño adds potential for stronger westerlies and higher extremes this year, yet model consensus and climatological variability keep the likelihood of a modest peak (below 90 km/h) roughly even with moderate (90–101 km/h) or higher outcomes. Official MetService and NIWA updates through early September will refine short-term steering patterns and intensification potential ahead of month-end resolution.

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.
