Wanaka was a record for MS since records began in the 1970s

Got as high as 30.6°C here, dewpoint 22.2° at the time. Quite uncomfortable.
Hoping it doesn't get too much hotter than that, or we have lower dewpoints if we do.

Can someone tell me what Hamilton’s January avg high temp is. I feel like it’s about 24? If so then is there a chance Hamilton will meet the 5 days of 5 degrees above avg high for a heat wave to be classed?

Yep. Here's the normal 1981-2010 January T-maxs for all the 6 main centres...
23.4C … Auckland, Mangere
23.6C … Auckland Aero
23.9C … Tauranga Aero
24.3C … Hamilton Aero
24.0C … Hamilton, Ruakura
20.3C … Wellington, Kelburn
22.6C … Christchurch Aero
18.9C … Dunedin, Musselburgh

Thanks Nev. So Hamilton Ruakura needs 29 or more 5 days in a row for a ‘heat wave’. I think 4 days will be achieved but not sure on the 5th day.

Note that NIWA use Hamilton Aero for their 'main-centre' temps and rainfall.

Just hit 27°C at 9.46am climbing rapidly, dewpoint already 20.1°C it's going to be a scorcher.

Not quite on topic, but it would be nice to know what the highest recorded NZ temperatures for each month are ... no easy way of doing that with standard access to CliFlo ... or perhaps NIWA has a list somewhere...?

Off topic slightly here but what would be the highest monthly mean recorded in NZ ?
I recall the upper North Island had monthly averages above 22C in February 2016, that could possibly be repeated this month.
In February 1998 Dargaville EWS averaged 23.0C (Tmax avge 28.7C, Tmin avge 17.2C). A site with the name abbreviated to "Auckland Regional Co" (alt 20m) claimed a 24.3C mean but I think that looks suspiciously high.

Swimming pool is now up to 31c and so doesn’t do anything to cool your body. Pretty sure we have never recorded more than 30 in the pool before.

Do you have something akin to solar heating? seems a lot warmer than I remember our pool ever getting up to.

No just black concrete pool. Normal big sized pool.

Thanks RWood. I'm picking there will be some averages above 22C this January. The nights have been incredibly warm around NZ last couple of weeks.

He's the one fueling this whole heat wave thing in the media, time will tell I guess.

The issue arises for multiple station or countrywide records - the standard CliFlo menus just give you individual station data, not consolidations - but Nev can probably do a direct SQL enquiry to the database ...?

I seem to recall the 850hpa temps in Feb 1973 were around 24-25C, with Tuesday and Wednesday getting to 20C at a push for Canterbury I’m thinking 38C will be around the maximum achievable temperature on those days...

What is your humidity or dew point when you normal go over 30 Richard?

As malja pointed out its moderately dry on 41% atm, gets much lower with a NW blowing

Christchurch radiosonde sounding for midday 7th Feb 1973 had 850 temp of 27 deg, surface temp 40 deg with dew point 2.5 deg. The NCEP reanalysis for that time only showed an 850 temp of 21 deg but then that is for grid spacing of 2.5 degrees
