Is Bali Chilly at Night? What Travelers Should Know

Evenings in Bali can feel very different depending on where and when you visit. While many imagine Bali as warm and tropical, night temperatures vary by elevation, season, and local exposure. This guide clarifies typical nightly temperatures, the influence of wet and dry seasons, regional contrasts across the island, how often nights actually feel cool, and practical packing advice so you can plan comfortable evenings and restful nights.

Typical nightly temperatures and monthly averages

Bali nights are generally mild but vary with elevation and the time of year. Coastal areas such as Kuta, Sanur, and Seminyak stay warm for most of the year, while inland highlands become noticeably cooler after sunset. The following averages and contrasts will help you decide evening plans and what to pack.

Coastal nightly averages

Along the coast, nightly temperatures typically sit between 22 and 26 °C. Monthly average minimums in popular lowland areas are: January 24 °C, February 24 °C, March 24 °C, April 24 °C, May 23 °C, June 22 °C, July 22 °C, August 22 °C, September 23 °C, October 24 °C, November 24 °C, December 24 °C. Humidity during the wet months can make nights feel slightly warmer than the thermometer suggests.

Upland and highland nights

The central highlands around Bedugul, Munduk, and the slopes of Mount Batur are markedly cooler at night. Average nightly lows run from 14 to 18 °C through the year, with the coolest months (June, July, August) averaging 14 °C and the warmest months (January, February, December) averaging 18 °C. On higher slopes, temperatures can drop into the low teens and occasionally below 10 °C during the coldest hours.

Monthly patterns that matter to travelers

June through August shows the most noticeable drop in night temperatures across both lowland and highland zones, with clearer skies and lower humidity making evenings feel fresh. The wet season from November to March brings warmer minima on the coast but more humid nights overall. Plan light layers for coastal evenings and a warm sweater or jacket for overnight highland stays.

With those averages in mind, next examine how the dry and rainy seasons change nighttime conditions and what that means for comfort and activities.

Nighttime differences between dry and rainy seasons

The character of Bali nights shifts noticeably between the dry months and the wet months. These contrasts affect temperature, humidity, wind, and the likelihood of post-sunset rain, so they matter for evening plans, sleep comfort, and insect exposure.

Understanding these predictable patterns makes it simple to choose clothing and evening activities for each season.

• Temperature swings — Coastal nights during the dry season usually fall to about 21–24 °C, while in the rainy season minima commonly sit higher around 23–26 °C. In the highlands the dry season brings clearer skies and lows near 12–16 °C, with the rainy season raising lows to about 14–18 °C.
• Humidity and comfort — Dry months have lower humidity, which makes cool evenings feel crisp and comfortable. The wet months keep nights muggy, so a warm night can still feel sticky if humidity is high.
• Wind and breeze — The dry season often brings steady southeast winds that create pleasant coastal breezes after dark, while the rainy season tends to have lighter winds leading to stiller nights near sea level.
• Rain timing and intensity — Heavy showers in the wet season frequently start late afternoon and continue into the night, quickly changing temperatures and raising local humidity; occasional overnight downpours may cool the air sharply for short periods.
• Insect activity — Mosquitoes and other biting insects are more active on rainy season nights after rain pools form, so expect higher nuisance levels and take basic precautions.

Overall, the dry season produces cooler, clearer nights—especially away from the coast—while the rainy season gives warmer, more humid evenings with intermittent downpours. Beyond seasonal shifts, location on the island also plays a major role in how nights feel.

Regional night climates: coast, highlands, Bukit and Nusa isles

Bali presents clear contrasts after dark depending on where you are. Sea-level locations retain warmth and humidity, while the central mountains cool significantly. The Bukit peninsula and the nearby Nusa isles display maritime variations that affect sleep comfort and evening plans.

Coast and lowland beaches

Coastal zones including Kuta, Seminyak, Sanur, and Canggu normally see nightly lows between 22 and 26 °C. Sea breezes can lower perceived heat after sunset, but humidity during the wet months makes nights feel sultry. Windy evenings are most common during the dry season when southeast winds bring persistent coastal airflow.

Highlands and volcanic slopes

Areas such as Bedugul, Munduk, and Kintamani cool dramatically at night, with typical lows from 12 to 18 °C. The coolest period is June–August when clear skies let heat escape and temperatures can dip to the low teens or occasionally below 10 °C on higher ridges. Even in shoulder months a warm layer is often needed once the sun sets.

Bukit peninsula and Nusa isles

The Bukit area sits low but is exposed and often drier than the western coast, with nightly temperatures near 21–24 °C and consistent breezes. Nusa Penida, Nusa Lembongan, and Nusa Ceningan share similar mild minima of 21–24 °C, though they feel cooler on windy nights and slightly warmer after rainy periods due to retained humidity.

Knowing these regional patterns will help you choose the right neighborhood and accommodation for the kind of evenings you prefer. So how often do nights actually feel cool in practice?

How often nights feel cool and when to expect it

How often Bali nights feel cool depends mainly on elevation, season, and local exposure. If you define "cool" as temperatures below 20 °C, coastal lowlands experience cool nights relatively rarely—roughly 5–15% of nights across the year—with the highest frequency during the dry months (June–August) when clear skies and strong southeast winds can push minima into the high teens. Inland highland areas above 600–800 meters are cool most nights, with about 65–85% of nights feeling cool year-round and up to 90% during June–August when lows commonly sit in the low to mid teens. The Bukit peninsula and the Nusa islands fall between these extremes, with cool nights occurring about 15–30% of the time overall and more often on exposed, windy evenings in the dry season. Cloud cover and recent rain also alter the perception of coolness: a heavy overnight shower can drop temperatures sharply for several hours even in lowland locations, while humid, cloudy nights feel warmer despite modest temperature changes. For travelers, this means expect regular cool evenings in Bedugul, Munduk, or Kintamani, and bring a warm layer for clear dry season nights even on the coast; if you stay in lower beach resorts during the wet season you will seldom need more than a light long sleeve, but early morning hikes or overnight stays at altitude require preparation for consistent cool nights.

Given these patterns, the right packing choices will keep you comfortable through coastal humidity and highland chill.

Packing and clothing tips for cool Bali evenings

Pack with layers in mind so you can adapt to both coastal humidity and inland chill. Begin with lightweight breathable base layers made from cotton or quick-drying technical fabrics. Add a mid layer such as a thin fleece or sweater you can remove as temperatures rise. Include a lightweight windproof jacket for breezy seaside nights and a slightly warmer insulated layer if you plan overnight stays above 600 meters. Bring long pants for dinner or evening walks and sleepwear that covers arms and legs to reduce mosquito bites. For footwear, pack closed-toe shoes if you expect early morning hikes or uneven paths, and sandals for relaxed beachfront evenings.

Also bring a compact umbrella or packable rain jacket for wet-season showers that may begin after sunset, a light scarf or buff for sudden wind chills, and thin wool socks for the coldest inland nights. Choose compressible, multiuse pieces to avoid bulky luggage, and pack basic insect protection and a small laundry soap bar to refresh layers during longer stays.
