Port Moresby Weather in September

September weather

September is warm and very humid, with highs around 28°C and little change after dark. Expect cloudy skies and some rain: showers fall on about eight days, while sunshine averages just over three hours a day. It's still one of Port Moresby's better months for weather.

You can visit the National Museum and Art Gallery, or take a drive to the lookout at Touaguba Hill between showers. But don't build your visit around a full day of sunshine at Ela Beach. The cloud and rain can make a beach day feel less inviting than the warm air suggests.

Independence Day

Papua New Guinea's Independence Day falls on September 16. Port Moresby marks it with public celebrations, including cultural performances and events around the city. Expect busier roads and more local crowds around the holiday.

If you hate crowds, plan your visit to central sights outside the holiday itself. September is part of the July-to-September stretch with the best overall weather, so it may draw more visitors than the wetter months. Still, Port Moresby isn't a major mass-tourism stop, and there's no reliable basis to promise that prices will be higher or lower.

Local tips for Port Moresby

Travelling with kids? Port Moresby Nature Park is a good choice for a warm, cloudy day. Its native animals and shaded paths give you something to do if rain interrupts outdoor plans.

One local tip: ask your hotel about transport to the park before setting off. It's outside the central area, and getting there isn't as simple as hopping on a regular city sightseeing bus. For food, try a local dish such as kaukau, a sweet potato often served with a meal.
