The wetter season lasts 5.3 months, from May 8 to October 16, with a greater than 28% chance of a given day being a wet day. The chance of a wet day peaks at 37% on July 18.
The drier season lasts 6.7 months, from October 16 to May 8. The smallest chance of a wet day is 17% on January 28.

Daily Chance of Precipitation
To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day in the year. Auckland experiences some seasonal variation in monthly rainfall.
Rain falls throughout the year in Auckland. The most rain falls during the 31 days centered around July 16, with an average total accumulation of 3.8 inches.
The least rain falls around January 30, with and average total accumulation of 2.1 inches.
Average Monthly Rainfall
We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.
Auckland experiences some seasonal variation in the perceived humidity.
The muggier period of the year lasts for 3.5 months, from December 12 to March 27, during which time the comfort level is muggy, oppressive, or miserable at least 4% of the time. The muggiest day of the year is February 2, with muggy conditions 14% of the time.
The least muggy day of the year is August 25, when muggy conditions are essentially unheard of.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

Temperature and Dew Point
There is only a single weather station, Auckland International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Auckland.
At a distance of 16 kilometers from Auckland, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.
The station records are corrected for the elevation difference between the station and Auckland according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.
Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
