Northern Ireland landscape lovers on course for spectacular autumn display of colour

The sunny spell at the end of September, together with six months of high sunshine, mean that autumn should peak in mid to late October if conditions stay favourable.

Simon Toomer, plant specialist at the National Trust, said: “The primary trigger for trees to begin the process of shutting down for the winter and shedding leaves is day length but weather conditions through the summer and early autumn affect the rate of leaf loss and intensity of colour.”

Throughout the year, factors like temperature, moisture and sunlight all contribute to the vibrancy of the autumn colours.

Warm summers with lots of sunshine help to increase the leaf sugar content, which in turn results in a range of pigments – from reds and oranges to greens, golds and browns – as leaves turn.

Simon said: “We’re just starting to see some of the maple trees begin to turn – from greens to reds and oranges. And, judging by how the weather has been over the past few weeks I’d expect our autumn colour to be at its peak in mid to late October.”

A wet spring and a hot summer followed by sunny autumn days and frosty nights usually makes for a dazzling leaf display. But, weather patterns will need to remain favourable through the first half of this month, with enough sunshine during the day, cold conditions at night and no intense storms or rainfall.

Meanwhile, a university study commissioned by the National Trust showed that spending time in a forest or woodland helps reduce blood pressure, lower cortisol (stress) levels and improve concentration and memory.
