Visiting Port Moresby in January

January: warm and very wet

January feels warm, sticky and often cloudy. The high is 29°C and the low is 27°C, with rain on 23 days. Showers can interrupt outdoor plans, and the limited sunshine makes long beach days less appealing.

You can still visit the National Museum and Art Gallery or explore central sights between showers. Keep flexible plans, and don't count on a dry day for a trip to Ela Beach. Heavy rain can also make walking around town less comfortable.

New Year and quieter streets

New Year's Day is a public holiday in Papua New Guinea. Some businesses may close, so don't expect every café or shop to be open. January is part of the wet season, while July to September are the best months overall. You'll generally find fewer visitors than in those drier months, and accommodation may cost less, though holiday travel can affect availability.

If you hate crowds, January can feel calmer at major sights. The trade-off is that rain may shape your day more than other visitors do.

Make the rain work for you

Plan indoor stops for the wettest spells, then use a break in the clouds for a short visit to Ela Beach or the Port Moresby Nature Park. Avoid building your day around a long outdoor excursion; frequent rain and thick cloud can make it a frustrating bet.

Travelling with kids? The Nature Park gives you a named, easy-to-reach outing, but check locally before setting off in heavy rain. For a practical city tip, arrange your ride back from Ela Beach rather than assuming you'll find transport waiting there. January's rain can make an unplanned walk back a damp one.
