Planning your day or trip? Here you will find the most up-to-date weather information for the city of Mount Hagen, including detailed forecasts and charts.

The climate of Mount Hagen, located in the highlands of Papua New Guinea, can be described as temperate tropical, reminiscent of an "eternal spring". Thanks to the significant altitude above sea level, there is no exhausting heat typical of the coastal areas. The temperature background is surprisingly stable throughout the year: average figures hold around +16°C, with daily highs up to +20°C and cool nights when the air cools down to +11…+12°C.

There are no distinct seasons, such as winter or summer, in the usual sense. The weather remains practically unchanged from month to month; however, travellers should consider the very high probability of precipitation. Rains in this region are a constant phenomenon, and there can be from 26 to 30 "wet" days in a month. Even in the conditionally drier period from June to August, precipitation falls regularly, although its intensity may decrease slightly.

Such stable and humid weather promotes the lush growth of vegetation, making the surrounding landscapes incredibly green. When planning your trip, be sure to bring a raincoat and warm clothes for the evenings, as high humidity combined with cool mountain air can create a chilly sensation.

The climate of Mount Hagen can be confidently characterized as "eternal spring". Thanks to its location in the highlands, there is no sweltering tropical heat here typical of the country's coastal regions. The temperature regime remains surprisingly stable throughout the year: average figures fluctuate in a very narrow range from +15.3°C to +16.4°C. December and January are conditionally considered the "warmest" months, when the air warms up slightly more, while June and July are the coolest period, although the difference is only about one degree.

During the day, the weather is usually very comfortable and mild. The maximum air temperature consistently stays at the level of +19°C...+20°C, creating ideal conditions for walks and exploring the local culture without the risk of heatstroke. There is no pronounced hot summer or cold winter in the traditional sense here; instead, travellers are greeted by steady, pleasant warmth that practically does not change from month to month.

However, special attention should be paid to daily temperature fluctuations, which are felt much more strongly here than seasonal ones. While you can wear light clothing during the day, the nights in the highlands are quite fresh and bracing. After sunset, the thermometer drops to +11°C...+12°C. The difference between the daily maximum and the nightly minimum is about 8 degrees, so warm items will definitely be required for comfortable sleep and evening relaxation.

When planning a trip to Mount Hagen, it is worth considering that precipitation here is a constant and practically daily occurrence. In this region of Papua New Guinea, there is no clearly defined dry season: rains fall evenly throughout the year. The number of days with precipitation varies from 26 to 30 per month, making humid weather an integral part of the local climate.

The highest amount of precipitation is usually recorded in March, when the level reaches 21 mm. The period from June to August can be called conditionally drier, as the volume of precipitation decreases to 7–8 mm, however, the frequency of rains remains high. Even in September, the "driest" month statistically, travellers can expect about 26 rainy days.

Such stability means that tourists need to carry waterproof clothing and footwear regardless of the date of their visit. Rains here are very frequent, but judging by the average volume indicators, they may not be too intense, rather resembling regular drizzle or light precipitation that maintains the constant freshness of nature.

The weather in Mount Hagen is distinguished by enviable stability: a cool and humid highland climate reigns here all year round. The main rule when packing a suitcase is complete readiness for precipitation, which falls practically daily regardless of the month. Be sure to bring a high-quality raincoat, a dense waterproof windbreaker with a hood, and a sturdy umbrella.

The temperature regime in the region resembles "eternal spring": during the day the air usually warms up to +19...+20°C, and at night it cools down to +11...+12°C. In such conditions, the principle of layering in clothing works best. Pack t-shirts for the warm daytime hours, but do not forget warm items: fleece jackets, sweaters, or a light jacket for cool evenings and early mornings. It is recommended to choose clothes made of quick-drying materials, as items made of thick cotton take a very long time to dry due to high humidity.

Pay special attention to footwear: for walking around the city and surroundings, comfortable closed boots or sneakers with non-slip soles, resistant to moisture and dirt, are necessary. Despite the absence of exhausting heat, the high-altitude sun can be quite active, so be sure to put sunscreen in your travel kit, as well as take sunglasses and a head covering. Also, insect repellent will be useful for protection during nature excursions.
