There is only one thing to do at the beach when the clouds arrive – build a sandcastle.
Around 90 people arrived at Old Hunstanton armed with buckets, spades and creative ideas.
The annual competition is designed to raise awareness of the RNLI and the important role it plays in keeping the coast area safe for everyone.
Crew members manned the nearby lifeboat station on Tuesday so visitors also had the chance to take a close look at the Atlantic 75 boat and the rescue hovercraft.
The contest has been held for more than 20 years and the organisers hope attendance will top 100 next year.
Entrants were charged £1 to take part and there were prizes on offer for RNLI vouchers awarded to the winning designs.
Everything from a unicorn to a pyramid was created on the sands along with the more usual castle-style.
Chairman of the Hunstanton and District Lifeboat Guild Terry Morris said the event had been a great success.
