The youngsters, who are thought to be local, were caught out at Sandyhills Bay, when the strong breeze and ebbing tide caused them to fall off their inflatables.
It sparked a huge air and sea alert involving a Coastguard Rescue helicopter, two lifeboats and two Coastguard Rescue teams.
Three other young girls who were on the beach heard the screams and waded and swam out to the two girls to try and help.
And four men who were were staying at the nearby Sandyhills Caravan site also went to their rescue,
The incident near the Sandyhills caravan site at Colvend brought a warning from Belfast Coastguards who co-ordinated the rescue.
A spokesman said: “These are not advisable items to use and we would urge parents not to allow children to use them on dangerous coastal areas like the Solway.”
He added: “Luckily this time the youngsters suffered only from shock and the cold.
“We can’t stress how dangerous this is, but fortunately in this incident they were saved. They were treated for the cold and then given advice before being taken home to their parents.”
Kirkcudbright and Porting Coastguard teams were on scene along with the Nith Inshore Lifeboat from Glencaple and Silloth Lifeboat from Cumbria which was on an exercise and was diverted to Sandyhills.
