The RNLI attended multiple rescues and performed "major first aid" as lifeguards began patrolling beaches across Devon and Cornwall once more.
Despite repeated warnings from the charity about the dangers of visiting coastal areas without lifeguard cover, eased lockdown measures saw thousands flock to West Country beaches.
Mr Dowie said it had put the charity in an "impossible situation", forcing bosses to "choose between keeping the public or our lifeguards safe".
As lifeguards returned to the sand, the RNLI say patrols were kept busy with, "multiple rescues, major first aids and countless preventative actions whilst adhering to social distancing measures and wearing appropriate PPE."
One incident at Constantine Bay on Sunday, 31 May, afternoon, saw three water based rescues performed at the same time a member of the public was having a suspected heart attack.
Lifeguards also attended multiple incidents across the counties where swimmers were swept out to sea by strong off-shore winds, or rip currents.
RNLI Lifeguard Supervisor, Lloyd Davies said: "The lifeguard’s main task is prevention and over the weekend with the beautiful weather and clean waves brought hundreds of visitors to the beach.
"Our lifeguards were constantly talking to the public providing beach safety advice and keeping everybody safe."
The lifeguards are so pleased to be back on some of our beaches working closely with other emergency services to help keep our beaches as safe as we possibly can.
The nine beaches the RNLI cover are:
Croyde Bay (Devon)
Anyone planning a visit to the coast should always follow RNLI safety advice:
Have a plan – check the weather forecast, tide times and read local hazard signage
Keep a close eye on your family – on the beach and in the water
Do not allow your family to swim alone
Do not use inflatables
If you fall into the water unexpectedly, FLOAT TO LIVE. Fight your instinct to thrash around, lean back, extend your arms and legs, and float
In an emergency dial 999 and ask for the Coastguard
