A weird reddish sky on the horizon, at mid-day, and very calm conditions at the beach on Sunday. Notice how the waves swooshing onto the beach are uneven. Reminds me of text-book formation of cusps, and indeed the sand is forming wee rolling hills (admiteddly hard to see in this photo). Although they are never strongly pronouced on this St Clair beach, unlike the Kentish gravel beaches I remember from my youth.
A patch of reddish sand - which on closer inspection turned out to be coarser grained material with a fair amount of broken shells. Nevertheless the gulls were feeding on tiny shrimps washed up on the tide-line, which they'd be doing all the way along, red sand or not.
