such a nice surprise to see the big yellow thing in the sky today.
with only 12 hours of sunshine recorded in the first 11 days of the month, i had forgotten what it looked like.
currently 1.8°C with a cool SE breeze.
expecting a mighty 5°C high today....
Was the sunshine reading from Greymouth, or where?
In Reefton.
Thats what Cliflo says, and i certainly don't doubt it. it's been a horrible month so far.
Remember there may also be a reduction due to topography? I think we talked about that last winter but can't remembr what was concluded, if anything.

I do remember, and I said I would endeavor to take a photo of the stations location. I haven't done that, but I will.
from what I can see there's nothing I would think that would affect it - there is a line of trees ~30-40m to the west. As for topographic affects, the rangers are a significant distance away. But i'll try to take some pics this week and you can have a look.

The trees might be significant, since your deficit relative to other Coast centres is quite big in winter, less so in other seasons. If the instrument mounting is not very high that could also contribute. There are 3 sites in the North Island where the EWS instrument is lower than the manual one was, and the totals obtained are lower than the old ones - a contrast to most cases where EWS has replaced manual.

I think any deficiency is likely caused by the large amount of fog we get in Reefton during winter. In May for example, we didn't have a single clear fogless day. this morning was the first we've had all winter and that was because there was a decent breeze blowing.
the majority of the "sunny" winter days have fog till atleast late morning, and sometimes it sticks round all day.
