The government has warned it could close down beaches if social distancing is not observed.
The warning comes after a major incident was declared in Bournemouth after thousands flocked to its beach.
Bournemouth, Christchurch and Poole council have said services were "completely overstretched" as huge numbers of visitors defied advice to stay away.
Pictures show huge crowds gathering on the beaches.
Health Secretary Matt Hancock said the government could use its powers to close public areas like beaches if social distancing rules are not being observed.
Asked if he would consider shutting some beaches in extreme cases after scenes in Bournemouth, Mr Hancock told TalkRadio: “Well, we do have that power.
"I am reluctant to use it because people have had a pretty tough lockdown.
"Everybody should be able to enjoy the sunshine. The key is to do it with respect. Stay with your households. Stay a good distance from other households.
"Outside is safer than inside. So, you have got to respect the rules. Respect the fact that social distancing is still important.
"We do have those powers – and if we see a spike in the number of cases, then we will take action.”
England's chief medical officer has echoed Mr Hancock's message, reminding the public that the virus hasn't gone away.
In a tweet, England's chief medical officer reminded the public that the virus, which is thought to have killed more than 50,000 people, is still in general circulation.
Professor Whitty said on Thursday evening: "COVID-19 has gone down due to the efforts of everyone but is still in general circulation
"If we do not follow social distancing guidance then cases will rise again.
"Naturally people will want to enjoy the sun but we need to do so in a way that is safe for all."
