As late summer arrives in Antarctica, temperatures remain warm, but start to cool again moving into March as the days begin to get shorter and darker. Whale watching is at its best with migrating whale pods begin to converge and get their final fill of krill and then begin their journey north. Whale sightings can include humpback, southern right, minke, sperm, orca and blue whales. On land, penguin chicks start to fledge and adult penguins begin to leave the Antarctic shores. Fur seals cover the beaches of both the peninsula and islands, whilst younger seals are at their most playful and inquisitive. For those wanting to follow in the footsteps of early explorers and cross the Antarctic Circle, this is also a good time of the year to do so, before the continent plunges into the darkness of winter.
