Rinjani Hiking Season 2026: April Weather Updates & Safety Guide

The 2026 trekking season officially opened on April 1st. Currently, all trekking gates are operating normally. However, for those planning to hike in the near future, there are several important weather-related factors to consider.

Current Weather Conditions

According to BMKG monitoring, the West Nusa Tenggara region is currently experiencing extreme weather in early April. Moderate to heavy rainfall is forecast to continue at least until mid-month.

On Lombok itself, the weather tends to be unpredictable: bright and sunny in the morning, but turning to rain in the afternoon until late afternoon.

Is It Still Safe to Trek Mount Rinjani?

To date, the Mount Rinjani National Park Authority (TNGR) has not issued any special warnings. Trekking continues to operate normally and is still considered safe via official routes.

Reports from the Rinjani Trekking Center team on the ground indicate the following weather pattern:

• Morning: Generally sunny. Trekkers can still enjoy clear sunrise and summit views.
• Afternoon: Light to moderate rain begins, typically when trekkers are on the trail between Post 2 and the campsite (on both the Sembalun and Senaru routes).
• Evening & Night: Upon arrival at the campsite, the rain usually subsides, but conditions tend to be foggy, so sunset views may be partially obscured.

Preparation Tips for Trekkers

To keep your journey comfortable even in wet conditions, ensure the following are ready:

• Proper Footwear: Use mountain boots with good grip, as trails will be slipperier than usual.
• Logistics & Clothing Management: A raincoat is mandatory. Make sure all spare clothes are wrapped in plastic or a dry bag inside your backpack to keep them dry even during heavy rain.
• Be Aware of Cold Temperatures: Campsite temperatures at night range from 10–12°C. However, for those summiting to the peak, temperatures can drop sharply to 4°C. Ensure your jacket and warm gear are adequate.
• Follow Directions: Always follow the instructions of your guide during the journey.

Before departure, it is highly recommended to monitor the latest weather forecasts through our official page. Make sure your physical condition and gear are in top shape.

Happy trekking and always prioritize safety!
