Yesterday was a truly extraordinary weather experience. I sat on the decking in the sun all afternoon, working my way through a number of books, loving the heat. But looking out over the estuary all morning and afternoon, it was bizarre to think that the sun could penetrate anywhere, because it was impossible to see beyond the folly on Pen Y Bryn. The first photograph was taken at noon. The water was quite invisible, and Ynys Las and Ceredigion were just a figment of the imagination. I checked regularly, because it was fascinating, but there were almost no perceptible changes until well into the late afternoon/early evening, when the second photograph was taken at just gone 4pm. The sand banks are visible, and Ynys Las can be just about detected, but Ceredigion is still shrouded in mist. The temperature was diving at this time, really chilly.
