Wow, look at how ridiculous February-June looks sun-wise! The average March high being 4.4C higher than the average April high looks really odd too - bet that doesn't happen too often! (How do you work out the mean? Using (high+low/2) would give an April mean of 5.9, not 6.5.)

Yes, it makes the chart look messy, and as an OCD sufferer, that isn't a good thing.

Amazing how much wetter it has been nationally than here. All these talks of records, not a single record has been broken here in terms of rainfall (with the possible exception of April).

Yup, it's not the first time this has happened. Happened in 2010 too.

The low maximums in summer are the oddest thing this year - not even a single day approaching or above 29C.

In the NZ context, "Dull" doesn't work with your climate. Compared to Perth, yes.
One could call the 35.4 hours Invercargill had in the 30 days 19/5/1954-17/6/1954 dull, or Waimate's infamous 60.4 hours for December 1959, as two very bad NZ examples.

I have some preliminary sunshine numbers for 2012 for a few stations of interest but am waiting for some of the manual ones' data to get to NIWA's CliFlo. However it is already clear that "Fakertane" - despite a relatively modest total for December of 218 (I'd like to think someone had calibrated its instrument back to more sane levels, but that won't be the case, just a cloudy month there) will head off Nelson by about 19 hours (2602 vs about 2583). I'll put up totals for those two plus Tekapo, Appleby and Blenheim in a day or so (those will be the top 5 in that order).
