{{blockquote|text="After having been dormant for a long time, this year the mountain began to be alive again.

The eruption of 1963 was one of the largest and most devastating eruptions in Indonesia's history.

On February 18, 1963, local residents heard loud explosions and saw clouds rising from the crater of Mount Agung. On February 24, lava began flowing down the northern slope of the mountain, eventually traveling 7 km in the next 20 days. On March 17, the volcano erupted (VEI 5), sending debris 8 to 10 km into the air and generating massive pyroclastic flows.

These flows devastated numerous villages, killing an estimated 1,100–1,500 people. Cold lahars caused by heavy rainfall after the eruption killed an additional 200. A second eruption on May 16 led to pyroclastic flows that killed another 200 inhabitants. Minor eruptions and flows followed and lasted almost a year.{{cite web |url=http://www.channelnewsasia.com/news/asiapacific/once-tremors-detected-bali-volcano-can-erupt-within-hours-9269148 |title=Once tremors detected, Bali volcano can erupt within hours: Volcanologist |date=3 October 2017 |author=Pichayada Promchertchoo |publisher=CNA |access-date=27 November 2017 }}

The lava flows missed, sometimes by mere meters, the Mother Temple of Besakih. The saving of the temple is regarded by Balinese as miraculous and a signal from the gods that they wished to demonstrate their power but not destroy the monument that the Balinese had erected.{{Cite journal|last1=Gertisser|first1=R.|last2=Deegan|first2=F.

In late 2017, the area experienced 844 volcanic earthquakes, peaking at 300 to 400 earthquakes on 26 September. The frequency and intensity of these quakes caused much alarm among seismologists, as similar volcanoes have historically been known to erupt with even fewer warning signs.{{Cite news|url=https://www.theguardian.com/world/2017/sep/26/bali-volcano-eruption-seismic-activity-mount-agung|title=Bali volcano eruption could be hours away after unprecedented seismic activity|last=Lamb|first=Kate|date=2017-09-26|work=The Guardian|access-date=2017-09-26|language=en-GB|issn=0261-3077}} Alert was raised to the highest level and about 122,500 people were evacuated from their houses around the volcano.{{cite news|title=Indonesian official: More than 120,000 flee Bali volcano |publisher=Fox News|date=28 September 2017}} The Indonesian National Disaster Management Authority declared a 12-kilometre exclusion zone around the volcano on 24 September.{{cite web|url=http://www.theaustralian.com.au/news/world/thousands-evacuated-as-bali-volcano-sparks-fear/news-story/7a323056f5e512345575a14cf4e1f213|title=Thousands evacuated as Bali volcano sparks fear|date=24 September 2017|agency=The Australian}}

In Bali, the wet or rainy season runs from November to March – but it does not wet the whole island equally. The mountain range of Gunung Agung creates a rain shadow that divides the island between a dry northern part (narrower) and a wet southern part (broader). In the 1984–2009 period, the average annual rainfall in the northern part was 1761.3 mm / year, while the southern part received 2024.5 mm / year.{{cite journal |last1= Rahmawati |first1= Novi |last2= Lubczynski |first2= Maciek W. |date= October 2018 |title= Validation of satellite daily rainfall estimates in complex terrain of Bali Island, Indonesia |journal= Theoretical and Applied Climatology |volume= 134 |issue= 1-2 |pages= 1–20 |url= https://www.researchgate.net/publication/320873103_Validation_of_satellite_daily_rainfall_estimates_in_complex_terrain_of_Bali_Island_Indonesia |access-date= 2024-05-10 }} See p. 515, 517.

Of the 27 wildfires recorded in Bali's forests and savannas in September 2023, 13 – nearly half – occurred in the area surrounding Mount Agung in the Karangasem Regency; 5 fires were in the Buleleng Regency (northern part of the island) and 5 were near Mount Batur in the Bangli Regency.{{cite web |date= November 6, 2023 |title= Rain has returned to Bali.
