The echoes always seem to map out the coast, generally from Porthcurno to Marazion.

Looks like ground clutter to me. Most of those echoes are missing from the Met Office radar,

So they are.

so I guess netweather.tv uses the raw data - or at least a supply that has less post-processing than the Met Office do. The give-away today is that the echoes are stationary when you would anticipate a movement around 20 mph today.

.. . and the fact that I've been outside since 13:00, and it's dry & bright - if mainly cloudy! There was 0.3mm associated with the showery front mid morning.

It certainly seems more of feature when the winds onshore - though that might well be down to the higher humidity associated with a southerly wind flow, rather than the direction itself.
