A dull and calm grey day on a Fenland drain with an almost perfect mirror reflection in the water.
The line of poles stretching into the distance have a pronounced lean towards the east highlighting the westerly direction of the prevailing winds. On this drain a powerful westerly, or even an easterly wind turns the drain into a stretch of water you could surf on.
By the time the waves reach the far end of the drain they are white horses and breaking as if they are hitting the beach.
Maybe we ought to be checking wind strength using the Beaufort scale and sea conditions.
