Visiting Port Moresby in December
December: hot and rainy
December feels sticky from morning to evening, with highs around 30°C and nights still warm. Rain falls on many days, and thick cloud often dulls the light. November is drier; January is wetter, so December sits between the two. The weather can interrupt outdoor plans, but showers don't rule out a visit.
The National Museum and Art Gallery makes a good rainy-day stop, while Port Moresby Nature Park works best when the skies are clear. Varirata National Park's trails can turn slippery, so don't count on a long hike after heavy rain. If you're visiting Ela Beach, expect warm water but less reliable beach weather.
Christmas in the capital
Christmas is a major holiday in Papua New Guinea, and Port Moresby can feel quieter as some residents travel to see family. Around Christmas and New Year, travel may be busier and accommodation pricier than in quieter months. July to September is a better time for drier sightseeing, but December can suit you if you're visiting family or want to see the city during the holidays.
Travelling with kids? The Nature Park is a handy outing, but check its opening arrangements around Christmas before setting off.
Make plans flexible
With frequent rain and limited sunshine, keep outdoor plans loose. A shower can make a planned visit to Varirata less appealing, while indoor sights give you another option. December's humidity also makes a full day of walking around Port Moresby tiring.
For a local practical tip, use the Nature Park's named entrance as your destination when arranging a ride; don't assume a driver knows which attraction you mean. If rain starts while you're near Ela Beach, head back towards central Port Moresby rather than waiting for the weather to clear.
