Plage des Carrés is generally considered family-friendly, though like all Atlantic beaches, conditions depend on tides and weather. The beach's characteristics make it suitable for families, but parental supervision is always essential. Check tide tables before visiting, as the beach appearance and swimming conditions change significantly between high and low tide. The presence of lifeguards during summer months varies, so verify current safety services. Rocky areas may be exposed at lower tides, requiring appropriate footwear. Always observe posted safety flags and avoid swimming in rough conditions or strong currents.

Plage des Carrés is accessible year-round, with different seasonal appeals. Peak summer months (July-August) offer warmest swimming temperatures and longest days, though expect more visitors. June and September provide excellent alternatives with pleasant weather and fewer crowds. Spring brings wildflowers to coastal paths, while autumn offers dramatic skies and sunset opportunities. Winter visits reward hardy walkers with peaceful seascapes and fresh Atlantic air. For swimming, late June through mid-September typically provides the most comfortable water temperatures. The beach's sunset-friendly orientation makes late afternoon visits worthwhile in any season.
