Best Time to Trek Mount Rinjani

The best time for trekking Mount Rinjani is during the dry season, which typically runs from April to November. During this period, the weather is more predictable, and the conditions for trekking are generally favorable. Here are some considerations for each season:

1. Dry Season (April to November):
   • May to August: This period is considered the peak trekking season for Mount Rinjani. The weather is relatively dry, and the skies are clearer, providing excellent visibility for enjoying the stunning views from the summit.
   • September to November: The early part of the dry season is still a good time for trekking. However, as November approaches, there may be a slight increase in rainfall.
2. Wet Season (December):
   • December: The wet season is characterized by more rain, and trekking conditions can be challenging. The trails may be slippery, and there is a higher chance of encountering rain, which can impact visibility. It’s generally not too recommended to trek during this period.
3.  January – March (Climbing is Closed) 
   • January to March: Towards the end of the wet season, there might be some improvements in weather conditions. However, trails can still be wet and slippery. At this period the mountain is closed by the Government for any trekking activities and reopened from the first April

It’s crucial to note that even during the dry season, weather conditions on Mount Rinjani can be unpredictable, and rain showers can occur. Therefore, it’s essential to be prepared for varying weather conditions and to check the local weather forecast before embarking on the trek.

Additionally, it’s advisable to check the status of the trails and the volcano’s activity before planning a trek. Sometimes, the national park may be temporarily closed due to volcanic activity or other safety concerns. Hiring a local guide is also recommended for a safe and enjoyable trekking experience.
