The climate in Alotau is distinguished by remarkable stability, typical of equatorial latitudes.

The hottest period falls on the months from December to March. During this time, the average air temperature holds at around 26.5°C, and during the day, the thermometer regularly rises to 29.6°C. This time of year is characterized by warm and humid weather, ideal for beach holidays, although tourists should be prepared for the tropical heat.

The nominal "winter," which occurs in the Southern Hemisphere in June and lasts through August, brings only a light and pleasant freshness, but certainly not cold. These are the coolest months of the year when the average temperature drops to 24.0°C. During the day, the air warms up to a comfortable 26.2°C, making this period an excellent time for excursions and active tourism without exhausting heat.

Daily temperature fluctuations in Alotau are moderate but perceptible, offering relief after the midday sun. The difference between the daytime maximum and nighttime minimum is usually about 6–7 degrees. Even in the hottest months, nights remain pleasant with a temperature of around 23.5°C, and in August, the air cools down to 21.7°C after dark, ensuring comfortable conditions for sleep accompanied by the sounds of tropical nature.

Alotau is characterized by a humid climate where precipitation is a constant companion for travellers throughout the year. It is difficult to distinguish a clearly defined dry season here: rains occur with enviable regularity from January to December. Thanks to consistently high temperatures, precipitation falls exclusively in the form of warm tropical rains, which refresh the air and sustain the lush local vegetation.

The frequency of rainfall is truly impressive: according to statistics, the number of rainy days varies from 24 to 28 per month. This means you may encounter precipitation almost every day, so completely dry days are a rarity here. Even in the calmest months, such as July and August, it rains for about 24-25 days, so a high-quality raincoat or umbrella will be essential items in your luggage.

Looking at the annual dynamics, the peak of humidity falls at the beginning of the year, especially in March, when the highest volume of precipitation and up to 28 rainy days are recorded. The relatively "dry" period can be called the middle of the year, particularly July, when rainfall levels drop to a minimum (about 7 mm), although the frequency of rain remains high. Overall, the weather in Alotau is consistently wet, and tourists should be prepared for rain at any moment.

When heading to Alotau, prepare for the warm tropical climate that prevails here year-round. Air temperature consistently stays in a comfortable range from +22°C to +29°C, so the foundation of your wardrobe should be light summer clothing. Opt for items made from natural breathable fabrics such as cotton or linen, as well as modern synthetic materials that dry quickly, which is especially relevant in high humidity conditions.

According to statistics, rain in this region is a very frequent occurrence and can fall almost daily in any month of the year. In this regard, a raincoat or a high-quality waterproof windbreaker are mandatory elements of your luggage. Footwear should be as comfortable as possible and ready to encounter puddles: quick-drying trekking sandals or light sneakers with water-repellent treatment are ideal. A compact folding umbrella will also be useful.

Despite frequent cloudiness, the sun in Papua New Guinea is very active, so be sure to pack sunscreen with a high protection factor, a wide-brimmed hat, and sunglasses. For evening walks, when the temperature may drop slightly, or for boat trips, a light sweater or long-sleeved shirt will come in handy, which will also protect against insects.
