Nusa Tenggara, Indonesia
The dry season (April/May to October/November) brings sunny days, lower humidity, and minimal rainfall. Temperatures consistently hover between 25°C and 30°C (77°F to 86°F) during the day. Nights often bring a slight drop in temperature, making evenings comfortable. The landscape, notably the vast savannas, transforms into a striking golden-brown during these months, creating iconic photographic opportunities. Road conditions are better, making travel to remote areas more accessible. This season sees clear skies and predictable weather, ideal for outdoor pursuits.
The wet season (November/December to March/April) features higher humidity and considerable rainfall, often arriving in heavy, short downpours rather than continuous rain. Temperatures remain similar to the dry season, but the increased humidity makes the air feel heavier. While the rain might disrupt some plans, it also brings a freshness to the air and fills the waterfalls to their fullest. Unpaved roads, notably those leading to remote villages and beaches, may become challenging or impassable due to mud and flooding, calling for more robust transportation or adjusting itineraries.
This period brings the most pleasant weather conditions for travel. Clear skies and minimal rain create ideal circumstances for beach activities, trekking, and general exploration. Most popular sites are easily accessible. This time aligns with peak international visitor periods, especially from Europe and Australia, seeking sun and cultural experiences. The golden savannas are at their most picturesque.
Higher demand for accommodation and tours results in increased prices. Popular sites, while not overwhelmingly crowded by global standards, see more visitors compared to other times of the year. Booking in advance holds importance for desirable accommodations.
