Spring 2024 was the warmest on record for Wellington and Paraparaumu, with data available since 1928 for Wellington and since 1953 for the Kāpiti Coast. Various warm nighttime records were also broken west of the ranges. Even though the mean seasonal wind was slightly below average, a persistent period of severe westerly flow produced an impressive 118km/h inland in Martinborough on 7 September, the second highest wind gust since records began in 2001. The total accumulated seasonal rainfall was near average around the capital, above average for the Kāpiti Coast and largely below average for most of the Wairarapa, with only about 50% of the normal spring rain falling in parts of the east coast. As a result, the eastern Wairarapa was classed as extremely dry by mid-December with potential to escalate further into the new year, before the synoptic flow reverses in response to the weak La Niña footprint.
