Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023
For Auckland, New Zealand, the climate data describe 2013–2023. The monthly mean temperature ranges from a tied low of 11.9 °C in July / August to a high of 20.2 °C in February, while mean daily rainfall and sunshine also vary across the calendar.

Climate overview
Temperature
Monthly mean temperatures are highest in February, at 20.2 °C. The coolest monthly mean is 11.9 °C, shared by July / August. These are averages for whole months, not daytime maximum temperatures, so they do not show the full range visitors may experience within a day. The unweighted mean across the calendar-month temperature means is 15.8 °C. It provides an overall summary, but is not a day-weighted annual average and should not be read as the expected temperature for a specific month.
Rain
Mean daily rainfall reaches its highest monthly level in September, at 3.78 mm/day, and its lowest in January, at 2.47 mm/day. The figures describe average amounts per day, not monthly totals; they do not indicate how often rain falls or guarantee dry or wet conditions on a particular date. The unweighted mean of the monthly mean daily rainfall figures is 3.21 mm/day. This is a broad annual reference rather than a day-weighted total or a measure of rainfall frequency.
Sunshine
Mean daily sunshine duration is highest in January, at 11.50 hours/day, and lowest in June, at 6.88 hours/day. These monthly averages can help with broad outdoor-planning expectations, but sunshine duration is not the same as day length and does not promise clear conditions on any particular day. Across the calendar-month means, the unweighted mean daily sunshine duration is 9.29 hours/day. It summarizes the monthly averages without showing how sunshine is distributed from day to day.
Best Travel Time Guide for Auckland, New Zealand: Ideal Seasons and Weather Insights
For visitors prioritising cooler monthly mean conditions, July / August is the relevant point of reference, with a mean temperature of 11.9 °C; this is not a daytime-high figure or a promise about temperatures on travel dates. If lower average rainfall is the priority, January is the conditional option, with mean daily rainfall of 2.47 mm/day. Visitors planning around rain should also note the higher monthly mean daily rainfall in September, at 3.78 mm/day; neither average tells how many rainy days to expect, so flexible plans and suitable rain protection remain sensible.
For outdoor sightseeing where average sunshine matters, January has the highest mean daily sunshine duration at 11.50 hours/day, while June has the lowest at 6.88 hours/day. These are separate planning considerations, not a combined best-time ranking: sunshine duration does not equal daylight length, and monthly averages cannot guarantee the weather on a particular day.
