About this time last week it had become apparent that Auckland was in for a bit more than just a wet Friday. While the state of emergency remains in place for another seven days, it appears the worst should now be behind us.
Last night, Niwa shared a fascinating thread on Twitter that breaks down some of the key facts and figures about Auckland’s wettest month on record. Here are some the toplines.
- There was a lot of rain
In January, Central Auckland had a monthly rainfall total of 539 mm – well above the previous record from 1869, of 420mm.
Putting the January figures into context, according to Niwa it’s: 45% of the annual average, 260% of the summer average and 850% of the January average.
- Even before last Friday, it was wet
January 2023 would have been a record wet month for Auckland even if the storm had not happened, said Niwa.
- Last Friday was a one in 200 year event
Last Friday alone saw Auckland hit by 280 mm of rain in less than 24 hours and 211 mm in less than six hours.
