Residents may be asked for their views. Brighton and Hove City Council will meet on Tuesday to decide whether a public consultation should proceed.
There is already a voluntary smoke-free scheme in the city's children's playgrounds. Now the beach and the city's parks could be designated as smoke-free zones.
The public consultation would run for 12 weeks.
Smoking on the beaches and in the parks in Brighton could be banned, if a public consultation goes ahead.
The consultation would start at the end of the months and last for 12 weeks.
It still has to be approved by the health board. A voluntary smoking ban already exists in all 43 of the city's playgrounds.

This follows on from the successful Stoptober campaign, which supported smokers trying to kick the habit.
Quit4Life, the Hampshire NHS Stop Smoking Service, helped 320 people meet the Stoptober challenge and successfully quit smoking in October.
"If you could see the damage smoking does to you, you would stop".
That's the message to smokers from a new hard hitting campaign being launched in Portsmouth.
Portsmouth City Council, local smoking cessation providers and Public Health England (PHE) are working together to support smokers to quit in the new year with a new campaign.
The 'Health Harms' campaign aims to show smokers the harm smoking does to their body.
Every time a person smokes, blood that is thick and dirty with toxins circulates through the body in seconds, increasing chances of heart attack or stroke.
It follows on from a successful Stoptober, where 1,136 Portsmouth residents signed up to quit smoking.
