Planning a trip to Solo or simply want to keep up with the weather? In this section, you will find up-to-date information on weather conditions, as well as forecasts and useful charts.

The city of Solo, located in Indonesia, is characterized by a tropical climate. Temperatures here remain high and stable throughout the year, with average values around 26-27°C. Fluctuations between day and night temperatures, as well as between seasons, are minimal, ensuring consistently warm weather.

In Solo's climate, two seasons are clearly distinguished: wet and dry. The wet season usually lasts from November to April, peaking in January-March, when rainfall is at its maximum and the number of rainy days can reach 29 per month. A significant amount of precipitation falls during this period. The dry season occurs from May to October, with the least amount of rainfall and rainy days in July and August. During these months, the weather is predominantly sunny and dry.

Thus, when planning a trip to Solo, one should expect consistently warm weather. The main factor to consider is the shift between wet and dry seasons, as this significantly affects rainfall and overall air humidity.

The weather in Solo is characterized by consistently warm temperatures throughout the year, which is typical for the equatorial climate of Indonesia. The average annual temperature fluctuates slightly, remaining within a comfortable range. The hottest months are usually September and October, when the average temperature reaches 26.9°C and 27.3°C respectively, and daytime highs can rise to 31.8°C in September and 31.7°C in October. The "coolest" months can be considered January, February, and July, with an average temperature of around 26.0°C - 25.9°C. Minimum night-time temperatures during these periods drop to 21.2°C - 22.7°C.

In Solo, there is no distinct division into "summer" and "winter" in the conventional sense. Instead, the climate is divided into dry and wet seasons, while the temperature remains high year-round. Throughout the year, daytime temperatures steadily hold around 29-31°C, ensuring hot and humid weather, especially during months with high rainfall (from November to April). Even in the so-called "cool" months, such as July, when the night temperature may drop to 21.2°C, the daytime heat with maximum values around 30.5°C remains palpable.

Temperature fluctuations between day and night in Solo are quite noticeable. The difference between average maximum and minimum temperatures during a month can range from 6.7°C (for example, in January: 29.4°C max and 22.7°C min) to almost 10°C (for example, in August: 31.2°C max and 21.3°C min, or in September: 31.8°C max and 22.1°C min). This means that after a hot day, evenings and nights can bring pleasant coolness, especially during months with less rainfall, such as July and August.

The clear division into wet and dry seasons in Solo determines the pattern of rainfall throughout the year, which is typical for the climate of Indonesia. The wet period is characterized by frequent but generally not heavy rains, while the dry season brings a significant reduction in precipitation.

The highest amount of precipitation falls between December and March. February stands out as the wettest month, with an average of 13 mm of precipitation recorded and about 28 rainy days. January and March are also characterized by high humidity, with figures of 11 mm of precipitation and approximately 29 rainy days for each of these months. November (10 mm, 26 rainy days) and December (10 mm, 28 rainy days), preceding the peak of the wet period, are also characterized by frequent rainfall. April, with 8 mm of precipitation and 27 rainy days, serves as a transition month to drier weather.

The dry period is most pronounced in July and August, when precipitation is minimal – about 1 mm in each of these months. August is the driest month, with an average of just 3 rainy days. In July, rains are also rare, with about 6 days of precipitation. The decrease in rain begins as early as May (3 mm, 14 rainy days) and continues into June (2 mm, 12 rainy days). September (2 mm, 7 rainy days) and October (4 mm, 14 rainy days) mark the gradual return of precipitation, heralding a new wet cycle.

When planning a trip to Solo, it is important to consider its tropical climate with warm weather year-round. Average temperatures consistently stay around 26-27°C, while maximums can reach 30-32°C. Therefore, the foundation of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton or linen. Don't forget comfortable shoes for walking around the city, high SPF sunscreen, a head covering (hat or cap), and sunglasses to protect against the intense Indonesian sun.

Solo experiences a distinct rainy season, which usually falls between November and April. The highest amount of rainfall and rainy days (26-29 per month) is characteristic of January, February, and March. If your trip falls during this time, be sure to bring a compact but sturdy umbrella and a light waterproof jacket or raincoat. Clothing made from quick-drying materials will also be very practical. It might be worth packing a spare pair of shoes or sandals that you don't mind getting wet, as downpours can be frequent.

The drier season in Solo lasts approximately from May to October, with July and August being the driest months with minimal rainfall and just a few rainy days. However, even during this period, the tropical climate can offer surprises in the form of short-term rains, so a small folding umbrella won't go amiss, especially in transitional months such as May or October. Although the weather remains consistently warm, a light sweater, shawl, or cardigan may be useful for air-conditioned rooms or in case of rare evening coolness, as the minimum air temperature usually does not drop below 21-22°C.
