A cold front slowly slides northwards over the South Island on Monday reaching the lower North Island in the evening. A weak, central Pacific El Niño continued during April, as patterns of enhanced rainfall persisted in the vicinity of the International Dateline. This is expected to be associated with a westerly quarter air flow anomaly. Near normal summer rainfall is likely for most regions; however, the north of the North Island has about equal chances for below normal or near normal rainfall and the west of the South Island has about equal chances for above normal or near normal rainfall.

New Zealand weather forecast. Despite a sharp cold snap in early August, seasonal temperatures are forecast to be near average or above average for all regions of New Zealand, owing to warmer than average coastal and regional sea surface temperatures. Some things will not look right and things might not work properly. Oceanic ENSO-neutral conditions will very likely persist over the next three months. September – November 2020 air pressure is forecast to be higher than normal to the east and lower than normal to the northwest of New Zealand.
Rain moves in to South Canterbury mid afternoon before clearing at night, staying mainly dry further north but there is the chance of a coastal shower later in the evening.Mostly cloudy for Otago with the odd shower, some rain for North Otago and perhaps Central Otago developing in the afternoon, clearing away in the evening. Rainfall is about equally likely to be near normal or below normal in the west of the South Island, about equally likely to be near normal or above normal in the east of the North Island, and most likely to be near normal in all other regions. Around midnight a southwest change pushes into Southland bringing rain, moving into Otago overnight.Max temperatures – Expect highs to reach into the mid 20’s for the South Island’s east coast, perhaps even late 20’s for the North Island’s east coast. Traditionally, this occurs farther east toward South America and during the early summer season. Some things will not look right and things might not work properly. Air temperature, rainfall, soil moisture and river flow predictions for the coming season. Seasonal climate outlook - December 2018 - February 2019 Mean summer temperatures are about equally likely to be near or above average. The atmospheric circulation around New Zealand is forecast to be characterised by slightly higher than normal pressure to the southwest and southeast of New Zealand and lower pressure than normal to the northeast of the country.
This is expected to be associated with developing La Niña-like northeasterly air flow anomalies, although a westerly flow anomaly, which may be strong at times, is favoured to continue for much of October. North of Greymouth skies are sunnier with some high cloud, the odd shower sneaks northwards through to about Westport in the evening however. Your web browser (Internet Explorer) is out of date. Tasman Sea surface temperatures may influence several spells of unseasonable warmth through the season, particularly in eastern areas, contributed to by frequent westerly air flows.
High cloud for Canterbury through to Southland (sun may break through at times), expect gusty northwesterlies especially in the afternoon / about inland areas.
Showers further south along the West Coast, perhaps becoming heavy about northern Fiordland / southern South Westland, easing evening.
This is expected to be associated with a westerly quarter air flow anomaly, particularly during November and December. Winds from the northwest ahead of the front changing south to southwest in behind. Patchy rain picking up south of about Waikato late afternoon / evening. Morning low level cloud about Wellington breaks to sun and some high cloud, winds gusty from the north.Mostly cloudy for the West Coast south of about Hokitika with showers, turning to rain for Fiordland at night with heavy falls.
During periods of northeasterly winds, the threat for sub-tropical low pressure systems capable of producing heavy rainfall, similar to those experienced in late June and mid-July, is elevated, particularly in the north and east of the North Island.
Mean summer temperatures are about equally likely to be near or above average. Mostly cloudy along the east coast, a few spits about Wairarapa spreading from the west late afternoon / evening.Rain for North Westland, heavy about Buller and Tasman then easing evening.
