COASTGUARDS are gearing up for one of their busiest periods ever as thousands flock to the coast to enjoy a sizzling summer.

As forecasters predict the hottest year on record, rescuers have been visiting schools to deliver important safety messages before the summer holiday break.

They will also have a presence at the first Youth Sailing and Marine Fair at the sailing academy on Portland next month.

The dangers of pier jumping and tombstoning,' boat and beach safety and the importance of not making hoax calls are key themes this year.

Adults too will be targeted in the education campaign as talks are given to specialist clubs.

Meanwhile, Don't drink and drown' beer mats will be distributed to pubs and clubs.

Although no overall figures are available, Weymouth sector manager for Portland Coastguard Rob Sansom said teams were working to deal with an increase in calls this year, thought to be linked to the long spells of warm weather.

The Wyke Coastguard rescue team for example, which covers the Weymouth area, has so far dealt with an extra 20 emergencies compared with last year.

"The indications are that it is going to be a busy summer so we're keen to get the safety messages out there," Mr Sansom said.

There has been an increase of hoax calls and Mr Sansom said he would continue to educate children about how this irresponsible action can compromise genuine calls for help.

Mr Sansom suspects the popularity of the programme Seaside Rescue - which has helped to raise the profile of the service - could be linked to the rise in calls.

Mr Sansom spoke as the Maritime and Coastguard Agency (MCA) launched its Sea Smart campaign for 2007.

Aimed at children and parents to prevent accidents and deaths on the coast, the campaign promotes a safety code for families visiting the beach.
