A large wildfire in the Dublin Mountains has died down considerably and is being monitored closely by a local landowner after more than 25 firefighters and other emergency services responded to the scene, according to the Dublin Fire Brigade. The blaze at Glencullen reignited following previous extinguishment efforts over the weekend, prompting a deployment that included four pumped appliances, a water tanker, a wildfire jeep based in Dún Laoghaire, and a senior officer, as stated by District Officer Darren O’Connor.
Emergency Response and Site Conditions at Glencullen
Emergency crews withdrew from the Glencullen site just after midnight after bringing the fire under control. Speaking on RTÉ’s Morning Ireland, Mr. O’Connor explained that the ground is tinder dry, noting that it will take a week of rain for moisture levels to return to normal. As moisture levels build back up in the peat and vegetation, the natural process is expected to either eliminate or slow down the fire completely.
Smoke Impact and Weather Factors in South Dublin
A significant change of wind direction and an increase in wind speed drove the smoke over the top of the mountain. After cooling, the smoke drifted down over south Dublin, leading to reports of a smoke smell from locals in areas near Glencullen. Mr. O’Connor described this summer as one of the busiest periods Dublin Fire Brigade has experienced in recent years, noting that the service has dealt with multiple significant fires along the Wicklow border due to prolonged weather conditions that made working conditions arduous and difficult.

Origin of the Wildfire
Authorities have not yet determined how the fire started. Mr. O’Connor stated that it is impossible at this stage to identify the source of ignition, though he noted that these types of wildfires generally start near pathways and roadways.

Expert Insight: Prolonged dry weather significantly lowers moisture in peat and vegetation, creating high-risk conditions where fires can easily reignite near roadways and prove arduous for emergency crews to contain.
