Where and what year was that recorded?

Bognor Regis (south coast) in 1990. http://www.metoffice.gov.uk/climate/uk/so/print.html
The average from 1971 - 2000 was 1902.9 hours. http://www.metoffice.gov.uk/climate/...nor_regis.html
General statistics such as totals for individual years for individual sites are not that easy to come by. This map is the best I could find. http://www.metoffice.gov.uk/climate/...ukmapavge.html

Cheers. The map will be a useful addition to my desktop, too bad I can't find such a straightforward format for NZ. The UK south coast is sunnier than the South Island south coast, with Invercargill and Dunedin only averaging 1600 hrs. Here is about 2500 hrs average, with this year looking to be right on the mark.

To be fair, both In'gill & Dunedin have averaged considerably more over the last 10-15 years, though allowance has to be made for an EWS at Dunedin and somewhat suspect manual records at Invercargill. Longterm records at Nelson & Blenheim (Motueka records are too short and currently not measured) are are round the 2450 mark, though Nelson has been outperforming this over the last 10-15 years.

I forgot that Dunedin recorded 2000hrs last year.
I hope the upward trend continues for Invercargill and Dunedin. If their climates were as good as that of Chch I would consider moving to either for their close proximity to quality surf/snow. There's lots of pluses about that end of the country, but climate isn't one of them (the voice of experience). Motueka needs a sunshine recorder again, as it's interesting information and the town is sidelined in the title stoush with those northern upstarts (Whakatane) without it.

Whatever they may claim, the data from the Whakatane EWS (and quite a few non-contenders with automated sunshine recording) is simply not credible. In the period when comparisons were always between simliar equipment, Whakatane topped the country only 2 times in almost 50 years.

Is the incredible data from NIWA's Cliflo? Is it corroborated by rainfall data (I guess there would be a correlation)? Who's to say that the old data wasn't in error and they have since improved on their old methods?

It's not corroborated by rainfall. Experience in the UK with the EWSs show that there are definite differences in results between EWS and manual, and it's very difficult to reconcile them. Philip Eden is an expert on this. The "old data" (manual) used to be centrally checked for consistency. This was stopped in the 80s, but essentially the results still looked in the main reasonable and site intercomparisons were fairly stable. In every case so far with new EWSs (bar 2 or 3 where the "exposure" is inferior to that previously) the new numbers look too high, even allowing for cases where the old ones looked a bit low due to site deterioration. I am in regular contact with a very experienced observer who has seen the unfolding history of the split-up Met. Service. He is totally dismissive of the equipment because it can record many hours of "bright" sunshine in cases where a veil of high cloud should have radically reduced the number.

I spent 16 years in In'gill and Dunedin. Yes, there were pluses, and we regularly escaped to a small bach near Alexandra. Central was pleasant for its low rainfall and brown landscapes contrasting with the greener bits, provided the valley winter fogs were avoided. I like the hinterland from Central through to the Mackenzie area.

Met. is not prepared to pay people for manual observations by and large these days. If Motueka gets a sunshine instrument it'll probably be electronic - then the inflated numbers should exceed those at Whakatane!

I guess that data has little commercial value once averages are established, even so , allowing inconsistencies and gaps doesn't seem like good practice (or good science).

Central and the Mackenzie have provided me with some spectacular days and weather over the years. We go down 2 or 3 times a year and I still find myself amazed at the quality of the light and the differing climatic conditions. The character of the Mackenzie Country has changed a bit over the years.
