A weekend of sunny, more settled weather could provide the "shot in the arm" the tourist industry needs, according to Westcountry tourism leaders.
Experts have said several days of sunny weather could lead to an increase in bookings and boost tourist interest in the region.
They said the welcome return of warm weather - after months of storms - could be "perfectly timed" as Britain begins to think about holidays again with spring fast approaching.
Temperatures are expected to hit 15C this weekend, around 50% above the seasonal average, with hours of sunshine predicted across the region.
Carolyn Custerson, chairman of Visit Devon, said the timing for a good weekend couldn't be better.
"If you get two, three or four days of good weather the phones start ringing and bookings start coming in," she said.
"70% of people now book their holidays online and a lot of holiday providers now have web cams and weather forecasts on their websites.
"It will boost consumer confidence for people to start booking their holidays at home. This will be that shot in the arm."
Malcolm Bell, the Head of VisitCornwall, encouraged people to share photos of the good weather on social media sites to boost interest in the region.
"I would encourage all people down here to get on Instagram, Pinterest, just take some nice pictures and share them. We have got amazing social media here, just take the picture and share it," he said.
"The clocks going forward always tends to shake the British out of their hibernation.
"I think it's going to be the start of the revival for bookings. Now the weather is much more settled people can get on to thinking about their summer holidays again."
Mr Bell said the tourist body had shifted its focus from the Open for Business campaign, which was launched in the wake of the storms and severing of the London Paddington to Penzance rail link, to a normal marketing approach.
"We will do something to celebrate the reopening (of the Dawlish rail link) but other than that it will be business as usual," he said.
"We know from foot-and-mouth that once the product is back up and running people will return."
Rick Turner, the director of the BIG Sheep and Atlantis Adventure Park in North Devon, said the spell of good weather is just what the region needs.
He said: "We have just had our first lambs put out, the grass is starting to grow, the leaves are coming back on trees. People have short memories and when the sun does come out everything starts to glow. I think it's going to be a very good year."
The news came at the same time a new study revealed, small firms have lost more than £830 million because of the floods. The Federation of Small Businesses (FSB) said the average cost per business in flood-hit areas was £1,531.
It said a third of small firms in flood-hit areas suffered from reduced demand for goods and services, while transport disruption hindered the movement of goods and supplies and led to staff absences in many businesses.
