Portland has a marine west coast climate with mild wet winters (35-40 inches of rain Oct-Apr), cool dry summers, and moderate temperatures year-round (rarely below 25°F or above 90°F).

Vinyl Low-E is the Portland workhorse for most homes; premium wood/composite suits historic homes; fiberglass offers the best dimensional stability in extreme temperature swings.
