The day started out fine at Bridal with some light smoke and north wind. Usually Bridal north wind = possibly Cheam altitudes so we had a big crew out, and we were indeed starting to get high, but the north wind also brought in the smoke from the inland fires, which started to impact thermic strength. Those of us at the Butterfly had to be patient to get high enough to make it back. The lower we got, the thicker the smoke got and the less thermal strength, if we could stay high we were OK.

A really interesting day of observing how the arriving smoke impacted thermic strength.
