What to expect
- Temperature feel - Heat-forward afternoons that stay fairly consistent through the day. Direct sun can push it into “hotter than expected” territory.
- Wet weather - Rain is a constant possibility. Expect damp surfaces and slick paths. You’ll want a proper rain setup rather than a ‘just in case’.
- Sun exposure - Very high UV is common. Outdoor time is best in the morning or late afternoon. It's the kind of sun you notice immediately.
- Exposure - A steady breeze, and you’ll notice sudden bursts, especially near the coast or ridgelines. On the water or higher ground it feels stronger.
