In California, 54 degrees means winter. People bundle up, wear gloves, and don fur lined hats.
Today, the temperature in Portland reached a sweltering 65 degrees (18 C). You can use your imagination of what happened.
BTW: If you're in the Portland area, I would recommend a trip to Wolfe's Neck Woods State Park. It's about 25 minutes north of Portland and just outside of Freeport. A great place to wander and enjoy spectacular ocean views.
