Extreme tropical humidity is yet to even peak in northern NZ, with Saturday looking to be the hottest, most tropical, day of this week. Saturday night/Sunday morning will be extremely muggy in the upper North Island.

As Cyclone Dovi unravels as it drops southwards it will drag down high humidity and heat from the tropics directly into the North Island. The South Island has a cooler air flow for the most part.

Auckland has a high of 26 to 28 degrees on Saturday (hotter if the sun comes out, which is possible) and coupled with very high humidity it may feel more like the mid to upper 30s if you’re outside and moving around. You read that right!

But the overnight lows may be where people feel it the most. Auckland’s overnight low on Saturday night will be 23 degrees, which matches Nadi, Fiji. Northern NZ literally will share the same air flow and temperature with very similar humidity levels too, and for many it may feel more like 30C at midnight.

For those who are sick of the humidity, there is a break coming. Auckland’s overnight low is set to tumble 6 degrees by Monday night, and it’s not just Auckland – most of the North Island will feel the cool down arriving on the back end of Dovi. Not everyone hates the humidity, especially people who may have moved to NZ from a tropical climate and finds NZ a bit too cool during our summers.

The South Island isn’t so impacted by the heat and humidity and a much cooler change spreads from the south on Saturday/Sunday and moves into the North Island over Sunday and Monday – depending on how the remnants of Dovi precisely travel. Most northern centres of NZ will have overnight lows drop several degrees by early next week, along with daytime humidex/feels like temperatures tumbling over 10 degrees by the start of the new week.
