Hope this is the correct forum, if not I apologise. I do own a FO WS.

Just looking at my June records today on the webpage, and I noticed that it said there were 6 dry days to 5 June. This cannot be correct, as this is only a 5 day period and not a 6. It was dry on the 31 May, so I am wondering if it is counting the last day in May as part of these 6 day days in June.

That assumption is correct. There was a debate about it when Steve introduced it and it was agreed it made sense to include days from the previous month. Otherwise you could never have a dry period longer than 31 days.

Steve, is it correct that if the whole of June was dry the count would be extended into July? Not that there's any chance of that happening in the UK!

I can see the point. However, as the section is monthly records - I find it strange it is including previous month's data. If it was "this year" or "overall", I could understand.

No worries though, and thanks for clearing it up.

It doesn't say No. of dry days in June.
It says "Longest Dry Period" (consecutive days) "up to" (date ending in June)

Yes, as beteljuice says, it's the longest dry spell ending at that point. It doesn't matter for how many days or months it's been continuing.

It's vaguely similar to things like average wind speed and pressure trend; they don't reset to zero at midnight, or at the end of a month. At the start of a period, they contain data that came from the previous period.

Yes understand now. I appreciate all the work you have put into this program, thanks.

Thanks Steve. Out of curiosity I looked on the User Map for stations where it would be dry for extended periods and this one is a good example. http://dsl.hutchey.com/record.htm Only 61 days! By the end of September I imagine it will be a lot higher.
