Britain is set for a ‘spectacular’ autumn – with colours even more glorious than usual, experts say

It’s almost time to get your jumpers out of storage and pour yourself a pumpkin spice latte, as autumn officially arrives on 23 September.

Experts from Forestry England say that the combination of a rainy spring with the record-breaking temperatures in June has paved the way for a ‘spectacular autumn show.’

Andrew Smith, director of Westonbirt Arboretum, said: ‘It’s amazing to see how all the different factors come together to create autumn colour every year. 

‘While the wet spring and reduced sunshine may bring delightful surprises, other elements also play a significant role. 

‘Factors such as genetics, tree species, elevation, and local climate conditions all contribute to the magical spectacle. This combination ensures that the intensity and timing of the autumn colours remain a wonderful mystery every year.’

Met Office data shows that this spring was particularly wet, with rainfall across Britain 55 per cent higher than average. 

While this rain may have dampened many Britons’ spirits, it did wonders for the growth of the UK’s trees.   

‘This abundance of rain has helped set the stage for a stunning display of colourful leaves in autumn,’ Forestry England explained. 

‘This is because the rain provided plenty of moisture to the soil, which helps to promote strong and healthy growth.’

Following this rainy spring, Britain basked in record-breaking heat in June, with temperatures hitting a daily average of 15.8°C – 2.5°C higher than average.

This sunny weather allowed Britain’s trees to flourish, according to Forestry England.  

‘Plenty of sunshine has meant a good growing season for the nation’s forests, helping them build up plenty of the sugars which produce the stunning autumn reds, golds and oranges as they are absorbed back into the tree,’ it explained.

‘Instead of following the usual pattern, the weather experienced in early spring could lead to a more gradual and enchanting shift in leaf colours this autumn, creating a beautiful mix of colours that are truly one-of-a-kind.’

The arrival of the autumn colours could also be influenced by the hot start to this month.

‘If temperatures remain high, this can delay the onset of autumn and the subsequent colour change in leaves,’ Forestry England said.

The leaves change colour when days become shorter and temperatures cool, with the green chlorophyll starting to disappear, leaving yellow and orange hues. 

‘So, while the warm weather may slightly alter the beginning of autumn, it can also extend it, offering more chances for people to witness nature’s splendid transformation,’ Forestry England added.
