Glider pilots have converged at Burketown in Queensland's Gulf country, chasing the rare morning glory clouds.

The meteorological phenomenon occurs in northern Australia during spring each year and attracts international interest.

The rolling cloud formation can sometimes be several hundreds of kilometres long, and because of their rarity, little is known about what causes the waves.

Caboolture-based pilot Al Sim found a morning glory cloud this morning near Mornington Island, his first for the season.

He said it was an extraordinary experience to glide the cloud.

"It is awesome, exhilarating and amazing," he said.

"It is the sense of the unknown I think — the unknown about how does this form, and we don't really understand that.

"I think it is just the adventure, the nature.

"It is very animated, the cloud is animated, and every cloud is different. It is like going surfing."

While the cloud appears in other parts of the world, Mr Sims said Burketown was the only place gliders can actually soar along its edge.

Mr Sim said spending time at Burketown is often on the bucket list for glider pilots from around the world.

Air space can be busy in a concentrated area as gilders converge to ride the wave.

Pilots can sometimes glide the cloud for a few hours, depending on its size and formation.

"We can cover in that time anything up to 900 kilometres," he said.

"We use the motor [in the glider] to get out and make contact with the cloud, and then we turn the engine off basically and commence gliding.

"The cloud is almost like running up and down a highway.

"So we have to be very aware and mindful of the fact that aircraft are in close proximity to where we are."

The Burketown region will host its first morning glory festival later this week.
