As if a bigger than usual moon wasn’t reason enough to toss and turn in the night the warmer, more humid, conditions one the way might not help either.
WeatherWatch.co.nz says an approaching low from the northern Tasman Sea is going to pull down northerly winds with the air coming from as far north as around New Caledonia.
Overnight lows will jump back up into the late teens and possibly even as high as 20 degrees in some parts of Northland.
The warmest regions will be Auckland, Northland, Bay of Plenty, Coromandel Peninsula and Waikato where temperatures at the coldest part of the night will only dip to 18 degrees – coupled with bright skies caused by the brightest moon is around 20 years both Sunday and Monday nights may be a little sleepless for some.
Regions south of about Central Plateau should be a little warmer however a high over the South Island will keep temperatures at similar levels.
The warmest night is expected to be Monday night/Tuesday morning north of Central Plateau says WeatherWatch.co.nz.
Overnight lows for the upper North Island after Tuesday will still be in the mid teens.
