Quick Answer
Is September not the ideal time to visit Antarctica?
September falls in Antarctica's toughest travel window (April – October). Antarctica is inaccessible by cruise outside the austral summer — sea ice locks up the peninsula and most expedition operators don't run trips at all. That said, it's usually the cheapest time to go if you can work around the trade-offs.
Antarctica's overall best season is November – March, and the toughest window to plan around is April – October. See the full month-by-month guide to compare every month at a glance.
