It’s finally — finally — warming up outside, and poised to get even warmer this weekend, with temperatures expected to reach the 80s.

Which raises the question: Where can you keep cool outside around Boston? Flocking to waterside locations is always a good bet, since outdoor pools and spray decks aren’t yet open for the season.

Don’t sweat it, though — we’ve compiled a list of places around the city where you can sunbathe, sail, or take a dip, now that spring has sprung. Be sure to check the websites for these locations before you head out, as some of these spots may have fees or other important before-you-go information.

Castle Island Overlooking the waters of Pleasure Bay, Castle Island is home to the historic Fort Independence, a boardwalk, and the legendary Sullivan’s hot dog shack. Take a breezy stroll on the Castle Island Loop (less than a mile) or, for a longer hike, the 1.8 mile Pleasure Bay Loop. And it you want to get in the water, there are several beaches nearby. 2010 Day Boulevard., Boston. mass.gov/locations/castle-island-pleasure-bay-m-street-beach-and-carson-beach.
