Sleepness nights ahead for some

A combination of increasing humidity, warmer nor’easters and a brighter moon every 24 hours this week means the week ahead may be an increasingly sleepless one for many Kiwis. says overnight lows won’t be overly hot but will be warm enough to be “uncomfortable for some”.

As a large high moves east of New Zealand the wind flow developing over many areas will be a nor’east one – with air that is both warmer and more humid drifting down across the country out of the sub-tropics.

On top of that, the moon is also heading towards being full – which means brighter nights. Winds will also be light, meaning the nights will be mostly calm.

Bright moons often cause sleepless nights for humans and other animals – but add on top of that increasing warmth and humidity and light winds and it makes conditions even more difficult for a solid nights sleep.

Cooler nights return to most places by this weekend and into next week – although the warm weather, especially for northern New Zealand, is likely to stick around well into April according to

Full moons at this time of year actually occur when the moon is furthest from the earth during its elliptical monthly orbit (apogee). So this Thu/Fri night’s full moon is probably the least brightest of the year, unlike September’s full moon when it will be at its closest (perigee) and brightest. But then we do generally get more cloud cover in spring than in autumn. 🙂
