JAKARTA, July 30 (Reuters) – Indonesia recorded a sharp increase in potential fire zones in July as El Niño conditions intensified across the country, the head of the country’s weather agency ​said on Thursday, adding that the weather system was expected ‌to last into early 2027.

Here are more details:

• More than 5,000 hotspots were detected as of July 29, a sharp increase compared to previous El Niño years in 2015, 2019 and 2023, agency official Ardhasena Sopaheluwakan said in an online briefing. ‌The ​provinces of West Kalimantan, South Papua and ⁠Riau recorded the most hotspots.

• ⁠As of mid-July 2026, 54.5% of Indonesia’s seasonal zones had entered the dry season, which is expected to peak in August, unchanged from a previous forecast, agency chief Teuku Faisal Fathani told the ​same briefing.

• The risk of forest and land fires is expected to peak from August to September, particularly on the islands of ⁠Sumatra and Kalimantan, before gradually easing from ⁠October to November when higher rainfall is expected to ​return to some areas.

• “The critical period for forest and land fires is ​expected from July through September 2026, making intensified monitoring and ‌surveillance in high-risk areas crucial to prevent hot spots from spreading and causing wider environmental damage,” Sopaheluwakan said.

• Dry spells have been recorded across much of the country, with the longest stretch without rain reaching ⁠80 days in Purworejo regency in Central Java.

• There were 1,366 locations with dry spells lasting 21-30 days, 943 locations with 31-60 rainless days, and ⁠70 locations where dry ‌conditions persisted for more than 60 days.

• The ⁠agency said hotspot activities have increased in West ​Kalimantan, heightening ‌the risk of forest and land fires and ​driving dense ⁠haze concentrations.

• The agency has conducted weather modification operations in several areas to reduce the risk of fires and limit their impact.

• The agency had previously warned farmers to adjust their farming activities to mitigate risks stemming from the extreme dry weather expected this year.
