Lombok’s tropical climate is shaped by the northwest monsoon, resulting in a clear division between the wet and dry seasons. The dry season, from April to October, brings consistently warm days (30–32°C), low rainfall, and up to 10 hours of sunshine daily. Humidity is slightly lower, and the air feels fresher, especially along the coast. Nights are comfortable, with lows around 20–22°C. This season is ideal for outdoor activities, trekking, and enjoying Lombok’s famous beaches, while the sea remains warm at 27–29°C.
The wet season, from November to March, sees frequent but usually brief and intense showers, often in the afternoon or evening. Daytime temperatures remain high (28–32°C), but humidity rises, making the air feel hotter and stickier. Rainfall peaks in December and January, with up to 18–21 rainy days per month, and the island’s interior becomes lush and green. While mornings are often clear, clouds and rain build later in the day. Tropical cyclones rarely hit Lombok directly but can bring increased wind and rain from January to April. Winds are generally gentle, with stronger gusts during storms, and the sea is always warm enough for swimming. Regional differences exist: coastal areas, especially in the south, are drier, while the mountains are cooler and wetter year-round. Lombok enjoys about 2,900–3,000 hours of sunshine annually, and even in the rainy season, there are sunny intervals between showers.
