Sequim's rain shadow — and why it still needs cleaning

Sequim sits in the well-documented rain shadow of the Olympic Mountains, which means noticeably less annual rainfall than Port Angeles and most of the peninsula. It's a real reason Sequim properties often look cleaner longer than homes closer to the coast.

It doesn't mean Sequim is maintenance-free, though. Mature tree cover in older neighborhoods, sprinkler and irrigation overspray on siding and fences, and shaded north-facing walls still bring algae and mildew — just on a longer timeline than in Port Angeles. Driveways and patios collect the same dirt, moss, and staining any exposed surface does in the Pacific Northwest.
