Time to swim

Yesterday's newspapers reported that water at a number of Irish beaches fail to meet EU standards for clean water.

On full tide Seapoint is a great place to swim. Clean too.

One would expect water at Seapoint to be warmer than lake water. But these days the water in Lough Dan in the Wicklow hills is warmer than at Seapoint.

Surprising.
