Tourists traveling in Bali between mid-July and August are being informed of a cool weather front that is rolling over the island.
While far from freezing, the cooler temperatures will undoubtedly be felt at night…it’s time to bring an overshirt or jacket to dinner!
In a public service announcement, the Bali Meteorology, Climatology, and Geophysics Agency (BBMKG) shared forecasts that the cold temperatures experienced by many over the last few weeks will continue until August 2025. This unseasonal coolness has been influenced by minimal cloud cover and low air humidity during the dry season.
Speaking to reporters, Wayan Musteana, Head of the Meteorology Operational Working Group at the Bali BMKG, explained, “The lack of cloud cover allows heat from the Earth’s surface to easily escape into the atmosphere through radiation.”
He explained that low air humidity during the dry season results in the absence of a “natural blanket” capable of retaining the earth’s heat at night. Musteana noted, “This intensifies the cooling process from night to morning, causing the air temperature to drop quite drastically.”
The BMKG shared more weather data and forecasting and explained that the current dry season in Bali is influenced by the east monsoon winds originating from the Australian continent. These winds are dry and cold, thus contributing to the cooling effect in several regions of Indonesia, including Bali. The average temperature in Bali over the last few weeks has been recorded at around 19 degrees Celsius in the morning and reaching up to 31 degrees Celsius during the daytime.
As of the end of June 2025, only around 30 percent of Indonesia’s seasonal zones (ZOM) had truly entered the dry season, with Bali having entered the dry season officially back in April. However, this year’s dry season is expected to be shorter than usual across Indonesia nationally, with rainfall tending to be above normal.
Extreme weather events have been noted across Indonesia in the last few months, as well as a series of natural disasters that have impacted Bali travel. The Indonesian National Meteorology, Climatology, and Geophysics Agency has issued updates on the potential for extreme weather as an indirect impact of Tropical Cyclone Wipha.
The extreme weather is more likely to occur in the Riau Islands, North Kalimantan, East Kalimantan and North Sulawesi regions of Indonesia, though tourists traveling in Bali and surrounding provinces are always reminded to keep up to date with the latest weather forecasts and wave predictions, especially if traveling by sea or taking part in marine tourism activities such as diving, snorkelling and boat trips.
While for many, the weather forecast is considered the most important thing to check on holiday, in Bali, the wave forecast is equally important, especially for those planning on enjoying beach days, surfing, or marine tourism activities. Over the weekend, the BMKG issued warnings of sea waves reaching 6m in height at key areas across Bali Province.
Tourists are reminded that while many of Bali’s beaches are safe, even more are home to dangerous undercurrents and rip tides, and only a few of Bali’s most famous tourist beaches have lifeguard stations. No swim zones are in place at many of Bali’s most picturesque beaches and must be honoured by visitors; this includes Kelingking Beach and Diamond Beach in Nusa Penida.
Tourists are encouraged to check in with their travel insurance provider prior to travel in Bali, and Indonesia more broadly, to ensure that they are up to speed with the claims process and have a clear understanding as to what is and is not covered by a policy.
In many cases, travel disruptions, delays, or cancellations caused by natural disasters are covered by travel insurance policies, but the level of coverage ranges greatly between providers and policy types.
