We'd done this hike a couple of weeks earlier and rain and drizzle made it a zero-visibility experience, which is also interesting, but not really what we wanted.
It's one of our favourite hikes, so we had to try it again before the summer temperatures got too high.
When the time came around the weather forecast again mentioned the chance of some rain, but we crossed our fingers and went out anyway. It worked out pretty good! Cool temperatures, and not a drop of rain until we were almost at the end.
