Auckland Weather January 2016 – Annual temperatures were above average (+0.51°C to +1.20°C above the annual average) in most parts of New Zealand, including large parts of the North Island and the western and southern South Island. A small band of above-average temperatures (>1.20°C above average) was observed in southern Manawatu-Whanganui. Elsewhere, near-average temperatures (-0.50°C to +0.50°C on average) occurred in South Canterbury, Otago, small parts of Auckland and the far north. 2018 was equal to 2
Annual rainfall in 2018 was above normal (120-149% of annual) over much of the eastern and upper South Island, as well as parts of Wellington, Wairarapa, Bay of Planet, North Waikato and Auckland. Above normal rainfall (>149% of normal) was observed in parts of South Canterbury. Rainfall was near normal (80-119% of normal) for the rest of New Zealand.
Auckland Weather January 2016
2018 started with almost normal soil moisture across the country, but soil moisture gradually increased in the North Island and Upper South Island in January. Widespread heavy rainfall from ex-tropical cyclones Feehi and Gita in February resulted in higher than normal soil moisture in much of New Zealand. Near-to-normal soil moisture persists throughout the fall, and near-normal soil moisture is prevalent throughout the winter. During the spring, soils were drier than normal in much of the country, although they remained wetter than normal in South Canterbury and Otago. Heavy rains in November brought more wet than normal soil to the east of both islands, while heavy rain events around Christmas did the same to the upper North Island. Soils were wetter than normal in the Upper and Eastern North Islands and much of the eastern South Island by January 1. Soils were drier than normal in parts of Taranaki, Tasman, West Coast and South Country.

The national average temperature for 2018, calculated using stations in the seven-station temperature series in 1909, was 13.41 °C (0.80 °C above the 1981–2010 annual average). This equates to 2018
Along with 1998, the hottest year on record, second only to 2016, was a year with a nationwide average temperature of 13.45 °C (0.84 °C above the 1981–2010 annual average).
Annual mean sea level pressure for 2018 was slightly below normal and higher than normal only west of New Zealand, and east of the country. This atmospheric pressure pattern produces slightly more northerly wind flow than normal for the year in the North Island, and more northeasterly to easterly winds in the South Island. This flow has contributed to above-normal annual rainfall in parts of the eastern South Island.
In 2018, temperatures in most parts of New Zealand were above average (+0.51 °C to +1.20 °C above the annual average). A small band of above-average temperatures (>1.20°C above average) was observed in southern Manawatu-Whanganui. Elsewhere, near-average temperatures (-0.50°C to +0.50°C on average) occurred in South Canterbury, Otago, small parts of Auckland and the far north. Most observed locations have record or near record high average, maximum and mean minimum temperatures.
Extreme Weather In 2016
For minimum temperature, 2018 set a new warm record of +0.94°C above the 1981-2010 annual average, surpassing the previous record of +0.80°C set in 2016. Research has shown that historical warming has been too high for minimum temperatures. Compared to the maximum temperature, but temperature estimates show differences – increasing daily ranges in some regions and decreasing in others [see Ministry for the Environment, 2018. Climate change projections for New Zealand].

Monthly temperatures in 2018 began with January recording a significant 3.1°C above the long-term average. With an average of 20.3 degrees Celsius, January 2018 surpassed February 1998 as the warmest month on record in New Zealand. On January 21, 2018, it was the fourth month
Centuries in which the temperature across the country is 2.0°C above average (after February 2016, May 2016 and December 2017). March and December were the other months that experienced above average temperatures (both 1.3 degrees above average). Three months, including February (0.8°C above average), July (1.1°C above average) and August (0.9°C above average) recorded above average temperatures. Meanwhile, six months, including April, May, June, September, October and November, had near-average temperatures (1981-2010 monthly average -0.5°C to +0.5°C).

Sea surface temperatures (SST) in the Tasman Sea and New Zealand coastal waters increased by 2°C to 4°C above average starting in November 2017 and continuing through February 2018. It has been described as an “ocean heat wave” because of its duration. and intensity. Surface temperatures in the Tasman Sea were the warmest on record in summer 2017-18, due to normal air pressure and light winds. For New Zealand, above-average SSTs fueled unusually warm weather, resulting in New Zealand’s hottest summer on record, as well as the hottest month on record (January 2018). (See Important Weather and Climate Events of 2018 for more details).
The statewide average temperature for the summer of 2017–18 was 18.8 °C (2.1 °C above the 1981–2010 summer average for a seven-station temperature series beginning in 1909); The only summer on record with a nationwide temperature 2.0 degrees above the 1981-2010 average. The summer of 2017-18 thus tied the record for New Zealand’s hottest summer, previously held in the summer of 1934-35.
2018 started on a wet note for much of the North Island and Upper South Island, although the Southern Lower Island had a very dry January. Ex-tropical cyclones Feehi and Gita brought well-above-normal rainfall to much of New Zealand in February. During the 20 February storm, Motueka-Riwaka recorded 148.4mm of rain between 04:00 and 18:00, or 173% of normal February rainfall in just 14 hours. 202.0 mm of rain was recorded in Kaikoura between 04:00 on 20 February and 10:00 on 21 February. This amount is almost four times the normal month, 28% of the annual normal rainfall, and it was more rain in less than 24 hours than November 2017, December 2017 and January 2018 combined.
The autumn was generally wetter than normal in the eastern parts of both islands, while on 28-29 April Rotorua received 167.8mm of rain in 36 hours, almost 1.5 times the normal rainfall for the whole of April.
Western Springs Parkrun
An easterly wind flow during spring brought more moist than normal conditions to the eastern South Island, particularly in November when widespread rainfall was observed. It was very wet in Otago, with Oamaru, Middlemarch, Cromwell and Lauder all observing their wettest spring on record. Conversely, many places in Auckland saw their driest spring on record, including Albany (North Shore) and Western Springs (MOTAT).
Soil moisture levels were below or better than normal in early 2018. Prolonged dry conditions forced the Ministry of Primary Industries to declare a moderate disaster for the Gray and Buller districts on January 10. The classification was extended to include Otago and Southland on 30 January. Widespread heavy rainfall from ex-tropical cyclones Feehi and Gita in February resulted in higher than normal soil moisture in much of New Zealand. Remains near or above normal soil moisture during fall, with normal soil moisture in winter. During the spring, soils were drier than normal in much of the country, although they remained wetter than normal in South Canterbury and Otago. Water restrictions began in Masterton on October 24 due to low spring rainfall. Heavy rains in November brought more wet than normal soil to the east of both islands, while heavy rain events around Christmas did the same to the upper North Island.
The greater Nelson region experienced New Zealand’s highest annual sunshine in 2018 (2555 hours), followed by the Bay of Plenty (2518 hours) and Marlborough (2503 hours).

March 2018 was characterized by significantly higher pressure than normal east of New Zealand. This pressure pattern, combined with the fading of La Niña in the Pacific Ocean, has led to stronger-than-usual northeasterly winds over the country. This warm, moist air mass, combined with the remnants of an oceanic heat wave in the Tasman Sea, affected New Zealand with higher than normal temperatures as well as heavy rainfall events.
March was a warm month across New Zealand, with average temperatures near average (>1.20°C average) or above average (0.51 to 1.20°C average) almost everywhere in the country. Just separated
