Mount Rinjani Weather

Mount Rinjani volcano is so big it creates its own weather!

Mount Rinjani, at 3,726 metres high, creates its own weather patterns, so while the rest of Lombok is experiencing a beautiful day, the top of the volcano can be surrounded in cloud. Normal temperatures for the lower altitudes vary during the year from 26 - 28 degrees Celsius (88 - 90 degrees Fahrenheit), so the temperature is very constant all year round.  Senaru Village is normally a full 5 degrees Celsius warmer than Sembalun Village. Lombok experiences much less humidity than its sister island of Bali just 45km away, so the climate is much more suitable for outdoor activities such as trekking.


Lombok, like all locations in the tropics and particularly near the equator, has a wet and dry season. Wet season commences around November and ends around March.  Normally, the mornings are dry, with the clouds building late in the afternoon in preparation for the 3.00pm downpour.  This lasts only an hour or so. If you are trekking Mount Rinjani, the object is to be above the cloud-line before 3.00pm, which means that as you are above the clouds, you do not get any rain at all!


Lombok experiences between 8 and 10 hours of sunshine each day, with February being the shortest days and September / October the longest.  The longer days of October and the lack of the wet season, makes October the perfect time of the year for trekking.

Altitude Effect

The lower slopes of Mount Rinjani are tropical to sub-tropical, with temperatures between 26 and 28 degrees Celsius, depending on where you are in relation to Mount Rinjani.  Senaru village, located on the very northern slopes of Mount Rinjani is very humid and hot, especially when in among the trees or deeper valleys. As you climb higher, the temperature drops rapidly, and around the Crater Rim area is quite cold, falling to as low as 8 or 9 degrees Celsius, so cold weather clothing is essential if you are climbing Rinjani.


There is little wind around Mount Rinjani generally.  As with most locations in the tropics, the air is very stable with very few low pressure cells to cause the winds found in the lower or higher latitudes.
