Best Seasons and Optimal Weather Conditions

Planning a successful trek to Mount Rinjani begins with selecting the most suitable time of year. The ideal trekking season in Lombok falls during the dry season, which typically spans from May to October. During these months, the weather tends to be stable, with minimal rainfall, clear skies, and temperate temperatures that make hiking safer and more enjoyable. The peak months of July and August are particularly popular, but they also attract larger crowds, so advanced booking is advisable.

Conversely, the rainy season from November to April can present challenges such as slippery trails, increased risk of landslides, and reduced visibility, which may compromise safety and overall experience. However, visiting during the shoulder months of May and October can sometimes offer a balance of better weather and fewer trekkers. Always check local weather forecasts before departure, and be prepared for sudden climate changes typical of high-altitude environments.

• Headlamp and extra batteries
• High-SPF sunscreen and sunglasses
• Insect repellent and personal medication
• Reusable water bottles or hydration bladder with at least 3 liters capacity
• Lightweight camping tent, sleeping pad, and cooking equipment (if camping)
• Portable charger and camera to capture the breathtaking views

It’s also recommended to carry a smallFirst Aid Kit, altitude sickness medication, and a detailed map or GPS device. Many guided tours provide comprehensive gear packages, but always confirm what is included and be prepared for unexpected weather shifts.
