Dungiven West

Took a speculative trip to Dungiven site this afternoon. On arrival, wind appeared to be slightly off to the NW and was a light 8-10mph. A large shower was approaching from the west and when it was over the wind died to flat calm then over the next hour the windsock went through a cycle of calm, westerly, south westerly, northerly, easterly and calm again. I got fed up and went home.
