Alma Bay
You'll wade into waist-deep water thirty meters from shore, the seabed still visible beneath your toes, while rock wallabies watch from the shadowed boulders above. The stinger enclosure runs the length of the bay, its white buoys bobbing in the shallows, promising safe swimming even through the tropical wet season.

Questions people actually ask about Alma Bay.
Is Alma Bay safe for swimming and suitable for families with children?
Alma Bay is one of Magnetic Island's safest swimming beaches and ideal for families. The bay features calm, sheltered waters protected by headlands, making it perfect for young children. During stinger season (November to May), a netted swimming enclosure provides protection from marine stingers. The beach has a gentle slope with shallow water extending far from shore. Lifeguards are not always present, so supervise children closely. The clear, calm conditions also make it excellent for beginner snorkeling around the rocks at either end of the bay.
What is the best time to visit Alma Bay?
Alma Bay is enjoyable year-round, but May to October offers the most comfortable conditions with warm, dry weather and no stinger risk, allowing unrestricted swimming. Summer months (November to May) are hot and humid with occasional rainfall and require swimming within the stinger net. Water temperatures remain pleasant throughout the year, ranging from 23°C in winter to 29°C in summer. For the calmest seas and best snorkeling visibility, visit during the dry season. Early mornings typically offer the most peaceful experience before day-trippers arrive from Townsville.
