Is May Right for You?
Weigh the advantages and considerations before booking
- + Last chance to see Antarctica before polar night locks in - research stations run final supply flights through mid-May
- + Aurora australis visibility peaks with 24-hour darkness - green and purple lights reflect off ice formations
- + Wildlife photography at its most dramatic - emperor penguins huddling in blizzard conditions, seals guarding breathing holes
- + Scientific stations welcome final visitors before winter isolation - McMurdo and Port Lockroy offer rare behind-the-scenes access
- − Extreme cold limits outdoor exposure to 30-45 minutes maximum - frostbite risk increases exponentially
- − Most tourist vessels cease operations by May 1st - only icebreaker expeditions with specialist gear operate
- − Weather windows shrink to 2-3 day periods between storms - flights from Punta Arenas frequently delayed 5-7 days
- − Emergency evacuation becomes nearly impossible - medical situations require weather-stable conditions lasting 48+ hours
Best Activities in May
Top things to do during your visit
May's 24-hour darkness creates perfect conditions for capturing aurora australis over icebergs. The combination of reflective ice surfaces and zero light pollution produces otherworldly green and purple illumination. Professional photographers guide small groups through -20°C (-4°F) nights using specialized cold-weather camera equipment.
Emperor penguins enter their most active breeding phase in May - males incubating eggs while huddling against -30°C (-22°F) winds. The contrast between harsh conditions and tender parenting creates outstanding wildlife viewing. Observation blinds positioned 50m (164 ft) from rookeries allow extended viewing sessions.
Watch McMurdo Station transition from summer research hub to winter survival outpost. Staff winterize buildings, store 12 months of supplies, and conduct final equipment checks. The controlled chaos of preparing for 6-month isolation provides unique insight into polar logistics.
May's stable ice conditions allow safe exploration of blue ice caves formed by compressed glacial ice. The 24-hour darkness enhances the turquoise glow from LED headlamps. Caves maintain constant -12°C (10°F) temperature, warmer than surface conditions.
May Events & Festivals
What's happening during your visit
Research stations mark the approaching polar night with traditional meals and equipment blessings. McMurdo's 'Winter Solstice Party' features the last fresh food deliveries, while Port Lockroy staff hand-write final postcards before six-month communication blackout.
