Ruakura (Hamilton) "warm days" very high tally 2nd year running

[cbm]

Wednesday 27th March was Ruakura's 79th day tmax >=25.0C for the 2018-2019 warm season. Possibly the last but would not rule out squeezing out a handful more before the middle of April.

2017-2018 the tally was 80, the last being 4th April.

In the context of this chart from here:

1998/99 was the only year to just tip over 70.

So to get values of 80 and 79* (still could creep into low 80s) two years running - well will certainly look significant when added to that chart.

Hmm… That annual warm days graph appears to bear little resemblance to either NIWA's Ruakura or Hamilton Aero figures?

Note that NIWA's days with a T-max over 25.0C means it has to be 25.1C or more.

So that would give Ruakura a tally of 76 days for the 2018-19 'warm-season' to date, 79 days for the 2017-18 season and 67 days for the 1998-99 season.

Also note that Ruakura recorded 91 days over 25.0C during the 2012-13 'warm-season', which is probably its highest tally since 1940 (no daily data available before then).

I did wonder whether needed 25.0 or 25.1C to qualify. There will be a handful of days right on 25.0C. I didn't make any effort to verify that chart, thought as it was published on a stats NZ site could rely on it
