It may not feel like it temperature-wise, but Locals’ Summer is here.

I’m talking about the month or so when the seasonal stuff is open but the tourists have yet to arrive.

It might be true that Portland is a year-round destination now (there was still a wait for Eventide on a bleak Saturday in March). And, you could argue, most of Maine won’t be busy during the week until after school gets out in June.

But in this short window before Memorial Day when it’s tolerable to be outside, Mainers can spend their weekends doing many of the activities we tend to avoid because they get too crowded.

Although the weather is usually better in the similar post-Labor Day period, with cruise ships and leaf-peepers around, there’s not as much of a lull. So, here are some activities to do as soon as you can.

Get a lobster roll at Five Islands

Sitting on a wharf overlooking the Sheepscot River, Five Islands Lobster Co. looks like the set of a movie — not from Hallmark, but an indie one that gets idyllic Maine right. The lobster comes directly from the waters around the scenic Georgetown seafood shack, and the drive that winds from Route 1 only adds to the experience. It opens on May 9, 11:30 a.m.-6 p.m. Saturdays and Sundays until June 19, when the schedule expands.

Play mini golf at Moose Mountain

In its fourth season, Moose Mountain Adventure Park in Richmond has two, 18-hole mini golf courses with water features, a bear cave and other Maine-related design elements. After opening for school vacation week in April, it’s keeping weekend-only hours through May. There’s also an ice cream stand and Amato’s food truck on site, along with a mining sluice where kids can pan for treasures.

Take a drive through Acadia

Different parts of Acadia National Park open at different times. In mid-April, the Park Loop Road, a 27-mile drive past many popular attractions, reopened to vehicles for the season (though there is a detour in effect). Closed for construction, the Cadillac Mountain Summit Road reopens after April 30 — and until May 20, you don’t need a reservation to drive it.

Ride bikes on Peaks

You can take a ferry to Peaks Island any time of year, but there’s not always a ton to do when you get there. Brad & Wyatt’s Island Bike Rental keeps some adult bikes available for self-service during the shoulder season but will be open on weekends starting in May, while Mike’s Carts opened for golf cart rentals in April. You can get a rum bucket and steamers, among a lot of other seafood, from restaurant Island Lobster Co. starting May 1. Some other seasonal spots, including the Umbrella Cover Museum, however, don’t open until Memorial Day weekend.

Eat Pier Fries in OOB

The amusement park rides in Old Orchard Beach won’t start up until late May, but the arcade at Palace Playland is now open Friday through Sunday. Pier French Fries will start serving up its iconic boxes of crinkle-cuts on May 1, though The Pier itself had yet to announce an opening day as of last week (it was mid-May last year).

Hike Mount Agamenticus

Spring hiking is always a gamble in Maine, meaning you’re better off sticking to more southern locations, like this popular hike in York, nicknamed Mount A. Choose from several routes depending on your fitness level, though none are too long or difficult, making it a good warmup for the hiking season. On Mother’s Day, there’s a nature printmaking workshop at the summit in the afternoon.

Hit the deck at The Porthole

While some restaurants and bars wait for consistent warm stretches to start serving outside, this spot on Portland’s waterfront makes the most of its expansive outdoor space, declaring last weekend that deck season has begun. With picnic tables, live music and a dedicated outdoor bar, you can soak up the sun while eating brunch, dancing or just looking out on the harbor with a beverage in hand.

Book a boat cruise

There are some summer activities, like swimming and sunbathing, that do require slightly better weather. Boat cruises are kind of on the fence. But you can bundle up as much as you want and, because you live here, hold out for a sunny day. Most charters, including nature cruises from Maine Maritime Museum and puffin tours out of Boothbay Harbor, only give Mainers a slight head start on the high season, getting going in mid-May. If you can get enough people together to keep the cost down, however, you can book a motor yacht cruise out of Portland Harbor starting May 2.
