It would help if you gave us a link to that site. Is it Irish, or
American? It the time in GMT, BST or local time?


Thanks for all the really helpful replies. Alastair, it's Metcheck which
Martin has indicated seems to be inaccurate. Their forecast for tomorrow has
the same peak as today which is between 16.00 and 18.59 which makes no sense
based on the replies you've kindly given. I do enjoy sitting in the sun but
like to avoid sunburn or over exposure which I've always assumed meant
around the lunchtime (i.e. in London from around midday till 14.00 give or
take a bit depending on the proximity to the longest day, cloud and so on)
but Metcheck had completely thrown me. I use several sources for the
forecasts, several from sites mentioned on this group, though I've no idea
where I got Metcheck from!

I now realise it can't possibly be right as it also shows an index of 6 in
the period till 21.59. What sites do you guys use that can be interpreted
by laymen like me?

Thanks,

Mike
