Re: General May Weather
Its prime time for thunder over the upper North Island. Polar jets are now coming north and there is still some warmth and moisture around.
That thunderstorm last night reached severe limits looking at reported hail size from west Auckland.

Re: General May Weather
MetService May 2019 Summary - An unusually dry month
Highs featured on the weather maps over New Zealand in May, keeping the rain makers away. It was an unusually dry May in the north and east of both Islands, even with the rain right at the end of the month. Many northern and eastern areas of the North Island recorded less than half of normal May rainfall. Abnormally low soil moisture continued across the North Island, especially north of Taupo. This reflects five months of higher than normal pressure over New Zealand, and five relatively dry months in a row.
Whangarei, Pukekohe, Hamilton, Taupo and Napier have all recorded less than 220mm of rain so far in 2019, based on data until the 30th. This is less than 40% of what is normal for Whangarei and about 50% of normal in the other areas.
May started out very cold across the North Island, but temperatures quickly rebounded to run extremely warm across the country for the remainder of the month.

Do you have the Kelburn sun value for the 31st? Not visible on CliFlo yet. I have 164.4 hours to the 30th (includes a late entry for the 4th). If the monthly total is 169 that is the highest since 171.3 in 1938, and the only other higher value was 172.5 in 1930 (record high).
Edit: 13.8C Tmean for May at Kelburn is a record high, or first equal.
Edit: can see 31st readings now. A quirk of the "daily range" search on CliFlo is in some cases having to choose an end-date beyond the range you want, to make all the data visible.

Re: General May Weather
Kelburn's T-mean adjusted to 13.7C, so 2nd-equal May highest (with 2011) after 13.8C in 2016. Its T-min of 11.2C was also 2nd highest after 11.4C in 2016. However, its T-max of 16.3C this May was a record.
Similarly, Musselburgh's T-mean of 11.8C was its 2nd May highest after 11.9C in 1999. Its T-max of 15.6C was also 2nd-equal highest (with 2007) after 16.3C in 1999. However, its T-min of 0.8C 8.0C this May was a record.

Re: General May Weather
A close thing though for Kelburn's Tmean - averaging the daily numbers gives a value just a whisker below 13.75C, while 2016's value is about 13.76C.Nev wrote: ↑Mon 03/06/2019 08:42Kelburn's T-mean adjusted to 13.7C, so 2nd-equal May highest (with 2011) after 13.8C in 2016.
