This is all we've had in Thanet since this 'heatwave' began. Not lovely.

Here in Blackheath it started off grey again but the sun was burning
through by 10 and this afternoon the sky has been a pale but real blue.
The cars are all covered with a thin layer of dust. Was it Sahara sand
in the air or pollution or what? It's jolly lovely now.

It is the wrong wind direction for Saharan sand. My guess would be
pollen. I have been suffering with hayfever this week.

Surely there can't be that amount of pollen in the air. We'd
all be dead, or at least wish we were. My guess is that the haze is
simply dust of European origin. The particles are small enough to
selectively scatter the blue, giving the fiery red of the setting sun.

I was referring to the dust deposits, not the haze.
