After three fully dry days (Aug 11–13) with warm temperatures and moderate wind, the rhyolite at Caseg Fraith should be largely dry on exposed surfaces. However, today's 0.1mm precipitation and elevated humidity (87%) introduce slight uncertainty, and the forecast shows persistent light drizzle over the next few days before heavier rain arrives on Aug 18.
