Weather in Goroka

Planning your visit? Find out what weather awaits you in the city of Goroka right now. Below are accurate forecasts and visual charts for your convenience.

The climate in the city of Goroka can be confidently described as "eternal spring". Thanks to its location in the highlands, a pleasant and mild atmosphere reigns here, devoid of the exhausting tropical heat typical of the Papua New Guinea coast. The temperature regime is surprisingly stable: throughout the year, average daytime figures stay at a comfortable level of +21…+22°C, whilst nights bring freshness as the air cools down to +13…+14°C.

There is no pronounced seasonality here, so the weather remains steady and predictable in any month. A characteristic feature of the climate is the high frequency of precipitation: "wet" days are recorded almost constantly, from 22 to 30 days a month. Despite this, the total volume of rainfall is small, suggesting frequent but likely light rains or mists that maintain the constant freshness and greenery around.

For tourists, this means that a trip can be planned for any time of the year without fear of extreme weather conditions. June and July are considered slightly cooler and a bit less rainy, but the difference with the rest of the year is barely perceptible. The main rule when packing is to bring layered clothing for cool evenings and be prepared for frequent variable cloudiness.

An analysis of temperature statistics in Goroka shows remarkable stability in the figures. At the beginning and end of the year (January and December), the average temperature is recorded at its highest mark — +18.2°C. The middle of the calendar cycle, falling on the period from June to August, demonstrates only a minimal decrease: in these months, average values are around +17.2...+17.3°C. Thus, the actual annual amplitude of fluctuations barely exceeds one degree.

Daytime maximums also remain practically unchanged. In the warmest period (from October to January), the air warms up to +22.1°C, whereas in the nominally "cool" months (June and July), the thermometer rises to +21.0°C. The difference between seasons is practically imperceptible physically and is visible only upon detailed study of meteorological reports.

Much more pronounced dynamics are observed in the daily context. Night-time figures hold steadily in the range of +13.3...+14.5°C throughout the year. Regardless of the month, after sunset, there is a noticeable cooling of the air, creating a contrast of approximately 7–8 degrees compared to daytime.

The climate of the city of Goroka is characterized by amazing stability and a high frequency of precipitation throughout the year. It is difficult to single out a clearly defined dry season here, as even in months with minimal rainfall, it rains for more than 20 days. Thanks to the mild temperature regime, precipitation falls exclusively in the form of rain, often creating a sensation of constant freshness and humidity.

The wettest period lasts from December to March. During these months, the probability of precipitation is maximal: statistics show up to 30 rainy days in March and December, and the peak in moisture volume falls in February (about 18 mm). Travellers planning a trip at this time should be prepared for the fact that an umbrella or raincoat will be needed almost daily.

A relative decrease in the amount of precipitation is observed in the middle of the year, from June to August. June is considered the "driest" month, when only about 4 mm of moisture falls, and the number of rainy days decreases to 22. Despite the fact that the intensity of rains falls during this period, overcast weather and light drizzle remain a common phenomenon for this region of Papua New Guinea.

When preparing for a journey to Goroka, it is important to consider that the climate here differs significantly from the hot coast: due to the location in the highlands, the weather can be characterized as "eternal spring". The average temperature during the day holds at a comfortable mark of about +21°C, however, nights can be quite cool, dropping to +13...+14°C. Therefore, the main principle when packing your suitcase should be layering: take T-shirts for noon, but be sure to stock up on warm items — a fleece jacket, a sweater, or a light jacket for evening walks and early mornings.

Particular attention should be paid to protection from moisture, as precipitation falls here with enviable regularity throughout the year: statistics show from 22 to 30 rainy days per month. Even if the rains are not too heavy, they are very frequent, so a high-quality raincoat or waterproof windbreaker will become your best friends on this trip. A compact umbrella will also be useful, but for excursions, it is more convenient to use membrane clothing that leaves your hands free.

As for footwear, give preference to comfortable closed models. Worn-in trekking boots or trainers with non-slip soles are ideal, ensuring comfort when walking on damp ground. Despite the moderate temperatures, the sun in the mountains can be active, so do not forget to put sunscreen, sunglasses, and a head covering in your luggage.
