Later we arrived at the picturesque town of Dornoch to see how the passive house was coming along.

The Haar came in as we looked along the beach.  This coastal fog is formed over the sea when warmer moist air moves over the relatively cooler North Sea causing the moisture in the air to condense. Sea breezes and easterly winds then bring the haar into the east coast of Scotland and North-East England where it can continue for several miles inland.
