Auckland, New Zealand's largest city, sits on a narrow isthmus in the north of the North Island, between two harbours and near the Pacific and Tasman coasts, at approximately 36.85°S, 174.76°E. It has a warm temperate oceanic climate (Köppen Cfb) — mild, humid and changeable, moderated by the surrounding sea — with warm, damp summers and mild, wet winters and no great extremes. Being in the Southern Hemisphere, its seasons are reversed relative to the Northern.

Summer, from December to February, is warm, humid and the sunniest, driest time of year, with January and February the warmest — average highs around 23–24°C tempered by sea breezes. Genuinely hot days above 30°C are rare, and the maritime setting keeps the warmth comfortable rather than scorching, though the humidity can feel sticky. Settled, sunny spells alternate with the occasional passing shower.

Winter, from June to August, is mild and wet rather than cold, with July the coolest month — average highs around 14–15°C and lows near 7–8°C, so frost is rare in the city and snow essentially unknown. The season is defined by rain, wind and changeable weather as Tasman Sea fronts sweep through, interspersed with mild, bright days. The ocean keeps temperatures gentle year-round.

Auckland is fairly wet, receiving around 1,100–1,240 mm of rain a year, spread through every month but with a clear winter maximum from around May to August, while summer is drier; rain often comes as showers driven in on westerly fronts. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Auckland's weather is famously changeable — the local saying is that you can get 'four seasons in one day' — as it sits in the path of eastward-moving weather systems off the Tasman Sea, with sunshine, cloud and showers often trading places within hours. Its position between two harbours keeps it breezy and humid, and remnants of tropical cyclones can occasionally track down from the Pacific in late summer, bringing heavy rain and strong winds.
