Still sunny here too but becoming very hazy.

Interesting to note that despite yesterday's (and the last month's) blue
sky, the sun index has struggled to make it much above 4 down here in the
South West. And yet, today (despite the milkiness/haze of the sky) the sun
index has gone above 6.

What was it in the previous air mass that filtered out much of the UV, even
when the sky was deep blue.

I would expect at this time of year we would be getting a sun index of 6 or
higher during clear conditions. Now we're back into a westerly regime, this
seems to be the case.

Currently at 14:55, 18.9C, RH 48%, DP 7.6C, 1017.2 mb (S), Wind 12 mph WNW,
Gusting 22 mph.
