Last time it was the bright blue summer of Australia. And now the blues are different, courtesy of another April day in London when the weather was schizophrenic.

I’m pleased it resulted in this capture – sailing craft racing on the nearby River Thames at Hammersmith. The angry dark blue sky is ripe for a downpour, while the sun shines on the river, dazzling shades of silvery-blue. And the sails are in another hue of the colour.

The wind played havoc with a couple of the little craft which capsized, depositing their sailors into the water. But just a short while earlier, the sky was kinder, a real canvas of beauty which really deserved another shot – showing how unsettled this island’s weather is at the moment.
