'Perfect storm' for Northern Ireland's surfers
A combination of tides and winds means that Thursday may have some of the best conditions Northern Ireland's surfers will see this year.
The surf forecast predicted offshore waves of 25ft on the north coast.
Ricky Martin from the Alive Surf School in Portrush said this is the kind of swell that local surfers look forward to and which "only comes in maybe twice a year or so".
"It is the perfect storm type scenario for surfers - you are looking for a low pressure sitting over Iceland that will send a swell right over to Portrush," he said.
And where there are big waves you will find some of the best surfers.
Champion surfer and Portrush local John McCurry has taken the day off work and will be driving around the coast seeking out some of the best waves.
"That's all part of it - a bit of exploration," he said.
Mr McCurry has surfed all over the world, in Central and South America and around the US, but says Ireland has "some of the best waves".
And many would agree.
Mr Martin said more and more foreign visitors were coming to the Northern coast to surf.
"Last year we had Californians, Floridians, Australians, South Africans, the French," he said.
"You name it, we taught them how to surf."
