The climate in the city of Rabaul can be characterised as classic tropical, with high humidity and remarkably stable temperatures. An eternal summer reigns here: throughout the year, average thermometer readings fluctuate within a narrow range of about +26…+27 °C. The heat is rarely extreme, but one should not expect significant cooling either — even at night, the air remains very warm.

Distinct seasons, familiar to temperate latitudes, are not observed in this region of Papua New Guinea. The weather is notable for its consistency, and rainfall becomes the main factor influencing tourist plans. Rain is a frequent occurrence in any month here, with the number of "wet" days remaining high year-round, peaking in December and January. Even during the relatively drier period from June to September, the probability of precipitation remains at a high level.

Travellers should be prepared for the sky to be cloudy most of the time; however, it is precisely thanks to this abundance of moisture that the local nature amazes with its lushness and greenery. When packing for your trip, it is best to stock up on light, breathable clothing and reliable rain protection, as warm tropical downpours can start suddenly on any day of the year.

The climate in this region is distinguished by amazing stability, characteristic of equatorial latitudes. When visiting Rabaul, tourists can count on consistent and warm weather throughout the year. The average air temperature remains practically unchanged from month to month, staying within a narrow range from +26.4°C to +27.0°C. There is no sharp change of seasons here, so the usual concepts of "winter" or "summer" are quite nominal — the warmth persists constantly.

If we consider minor seasonal fluctuations, the nominally "hotter" period falls at the beginning and end of the year; for example, in October and January, daytime maximums reach the +28.9°C mark. July and August can be called the "coolest" months, although the difference is barely perceptible: average figures at this time are around +26.4°C. Even during this period, the weather remains mild and comfortable, without sharp drops in temperature.

Daily temperature variations are also minimal and predictable. The difference between the daytime heat and the night-time is usually only 3–4 degrees. The nights here are very warm: even in the "coldest" months, the air temperature rarely drops below +24.8°C. This creates an atmosphere of eternal summer, where light clothing is appropriate around the clock, regardless of the date on the calendar.

The climate in this region is characterised by high humidity and frequent rainfall throughout the year, so Rabaul can hardly be called a place with a distinct dry season. In Papua New Guinea, rain is an integral part of nature, sustaining the lush tropical vegetation. Travellers should be prepared for regular precipitation, and sunny weather can quickly change to rain.

The wettest period falls during the winter months and early spring. From December to March, the number of days with precipitation reaches a maximum: for instance, in December, it can rain for up to 29 days a month, and in March — about 28. Despite the high frequency, the total volume of precipitation is distributed fairly evenly, with a small peak in February (about 14 mm).

Even in the relatively "dry" months, such as June and September, the rains do not cease completely. At this time, the number of rainy days decreases only slightly, averaging 21–22 days per month. June is considered the month with the lowest volume of precipitation (about 5 mm), yet an umbrella or raincoat will still remain necessary accessories for comfortable walks.

When preparing for Rabaul, be ready for the fact that the weather here is enviably consistent: warm and humid all year round. The average air temperature holds steady at around +27°C, so the basis of your luggage should consist of light items made from natural fabrics, such as cotton and linen. Loose t-shirts, shorts, and summer dresses will ensure comfort and good body ventilation. Be sure to bring a wide-brimmed hat and high-quality sunglasses to protect against the active tropical sun.

A feature of the local climate is the large number of cloudy and rainy days — precipitation is possible in practically any month of the year. In this regard, a light raincoat or a compact umbrella will become indispensable companions on your trip. Footwear should be comfortable and non-slip: light, breathable trainers or trekking sandals that dry quickly and securely fix the foot are excellent for excursions.

Despite the heat, it is recommended to pack one light long-sleeved top or a windbreaker in your suitcase. It will be useful not so much for warmth, but for protection against insects in the evening or from the wind during sea trips. Also, do not forget sunscreen with a high protection factor and repellents, which will make your time in nature much more pleasant.
