Imperial College London Study Analyzes Changes in Wildfire Weather Patterns in Northern Ireland

Northern Ireland faces a growing threat from wildfires as conditions become more favorable, according to a new report from researchers at Imperial College London. The study identifies the biggest change in wildfire conditions occurring in spring, traditionally the peak season for such risks.

Drought and fire-prone weather have become more common during this period, with spring drought events happening more often and a sharp rise in fire weather—a mix of warmth, dryness, and wind that allows fires to ignite and spread rapidly.

Dry vegetation such as grass and heather can easily burn in spring, intensifying the danger when combined with these shifting patterns. The BBC reported that experts warn this combination, along with climate change, creates a longer and more volatile wildfire season.

Theodore Keeping, a research associate in the analysis of extreme weather and wildfires at Imperial College London, stated that climate change is having a clear, exacerbating effect on wildfire danger in the UK.

Keeping added that there is an increased likelihood of severe spring drought in many parts of the UK due to greater warming. Warmer weather dries out vegetation earlier in the year, while the atmosphere draws more moisture from the ground, leaving landscapes flammable for longer periods. The report emphasizes that these processes now affect spring conditions even without record-breaking heat.

While spring remains the main concern, the findings also highlight a growing wildfire risk in summer months. Data shows an increase in periods of severe fire weather during summer, suggesting Northern Ireland could face a longer fire season in the future. Historically, summer fires have been relatively uncommon in the region.

That trend shifted in the previous summer, when temperatures exceeded 40C for the first time in parts of Britain. The extreme heat stretched fire services to their limits and underscored how rising heat and dryness can rapidly escalate fire risk. Researchers at Imperial College London produced the report to analyze these patterns, drawing on figures that confirm the sharp rise in spring fire weather.
