Tsunamis and landslides are not rated for a single city here. Climate risk profile of New Zealand
A 100-year river flood would stand 0.19 m deep in the centre of Auckland.
Sydney: Dry at the city centre point.
Auckland's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, Auckland's climate will still be more like its own today than any other large city's. The nearest other is Sydney (Australia).
+1°C
Mean temperature over the year
+1.3°C
Highest in the warmest month
+0.9°C
Lowest in the coldest month
-5%
Precipitation over the year
Under high emissions, the nearest is Sydney (Australia), and only in part.
Its own climate today is 1.4 σ away. How close the match is: 3.6 σ to the climate of Sydney today, where under 2 is close and over 4 is no match (Mahony et al. 2017). 3 of 3 climate model runs name the same city. Seasonal temperature and rain are compared, not extremes, city heat or the sea.
Where else Auckland stands out
17 days
Days with 20 mm of rain or more in 2025
Sydney: 19 days.
Higher than in 77% of the world's 630 large cities
Hazards at Auckland
Read at the city's centre and compared with the Atlas's 630 large cities. Moderate emissions is the IPCC's scenario SSP2-4.5.

| Sea level rise by 2050, moderate emissions | 216 mm | Among large cities: above 55% | |
| Water stress | Low (<10%) | Among large cities: above 0% | |
| Drought risk | Low-Medium | Among large cities: above 1% | |
| Earthquake shaking, once in 475 years | 1.62 m/s² | Among large cities: above 73% | |
| Land burned in an average year | 0% | ||
| Cyclone wind, once in 100 years | 26.27 m/s |
Flood depth is read in a single 1 km cell at the city's centre, in today's climate. Other parts of the city can still flood. The country page names the deepest point near a coastal city in 2080, so its figure can be higher. See how deep a river flood reaches around Auckland on the live map
