    Climate

    Temperatures vary greatly. The lower altitudes are often hot, while the forests and higher altitudes can be surprisingly cool. In May, the average daytime temperature in Borneo is in the mid 80s°F (28°C), with highs in the low 90s°F (33°C); the evenings get down into the mid 70s°F (24°C). There is very high humidity in the lowlands, and it will feel much warmer. Temperatures in the forest and at higher altitudes are only slightly cooler, averaging 60 to 80°F (16 to 26°C). Although May is considered the dry season, rain is still possible.

    Fitness Level

    Most wildlife viewing is done from vehicles, boats, and on foot. Walks to search for wildlife are generally 2-3 hours long and along relatively flat trails, gravel roads, and single-track trails that are undulating. You have the option to split into smaller groups based on desired level of exercise. In Sepilok, Tabin, and Danum, the heat and humidity can make a 3 to 5km walk feel like double the distance. Drinking water is imperative. Please contact us if you have any health concerns that may make this trip challenging.
