I'm unable to browse the internet in real time or access current data. However, I can suggest a few general types of events and activities you might find in Portland, Maine during the winter season, based on historical patterns and typical offerings in the area. For specific details, I recommend checking local event calendars or tourism websites. Here's a fun and informative guide for exploring Portland, Maine this week:

Kick off your week with a visit to the Portland Museum of Art. They often host rotating exhibitions featuring both contemporary and classic works. Spend a leisurely afternoon exploring the galleries and don't miss the gift shop for unique, art-inspired souvenirs.

In the evening, head to one of Portland's many cozy breweries or pubs. Allagash Brewing Company is a local favorite, offering tours and a wide selection of craft brews, including their famous White Ale. Many breweries in the area also host trivia nights, so check local listings for some fun team events.

If you're into live performances, see what's playing at the historic State Theatre. Known for its diverse lineup, you might find anything from indie bands to stand-up comedy. Check their schedule for a night that suits your fancy.

For those with a taste for adventure, venture out to the nearby Eastern Promenade for panoramic views of Casco Bay. Winter might just be the perfect time for a brisk walk or, if there's snow, try some cross-country skiing or snowshoeing. Don't forget to bundle up!

As the weekend approaches, consider visiting the Portland Farmers’ Market. Even in winter, you'll find an impressive array of local produce, artisanal goods, and maybe even some early-blooming flowers. It’s a great spot to grab fresh ingredients for a hearty homemade meal.

Saturday could be your time to dive into the local music scene. Many bars and smaller venues like One Longfellow Square or Portland House of Music and Events host live music events, featuring local acts along with touring musicians. It's a great way to enjoy regional talent and expand your playlist.

Finally, wrap up your week with a Sunday brunch at one of Portland's beloved eateries. Duckfat, known for its fries, and The Front Room, with its satisfying comfort food, are two standout choices. Take your time, savor a delicious meal, and maybe even try a classic New England lobster roll.

While my information isn't up-to-date, I hope these suggestions provide a starting point for a memorable week in Portland, Maine. Enjoy the charm of this vibrant city and explore whatever events might be unfolding while you're there!
