The stretch of unseasonably warm weather has given us an early case of spring fever. The only cure: a family beach day. Here are three seaside spots that combine sun, surf, and swings.

Mother’s Beach
This aptly named slice of seaboard sits on a man-made lagoon along the harbor, offering serene swimming in the calm waters of a lifeguard-protected haven. The four-acre marine park hosts a playground-on-the-sand with swings and slides, sheltered picnic tables, and a clear view of sailboats silhouetted in the afternoon sun. Heaven. 4101 Admiralty Way, at Via Marina, Marina del Rey.

Zuma Beach
The fabled waves of this legendary shore have long conjured images of surf punks protecting their turf. The reality? All California kiddos are welcome at this Malibu beach. With swings, volleyball courts, and a rock-climbing wall tucked into the south end, this is one stretch of sand calling for a family day out. 30650 Pacific Coast Highway, between Trancas Canyon Road and Guernsey Avenue, Malibu.

Ocean Park
Though the Santa Monica Pier is the go-to destination for an old-fashioned carnival with older kids, just a mile away you’ll find the tot-friendly plaza of your parental dreams. Locals know the Ocean Park playground presents two ocean-view toddler play areas, three swing sets, and access to the famed boardwalk bike path. A nearby snack bar and restrooms are just icing on the melting cake. 2400 Barnard Way, at Ocean Park Boulevard.
