Traveller notes on Hermanus in January
Hermanus's forum is upfront that January is the wrong month for the whale watching the town is famous for — the season runs June through December, peaking in August and September, so January visitors mostly miss out bar the occasional early mother-calf pair. Regulars say it's still worth the stop for the cliff path, galleries and cafes even without the whales.
