Dogs on Porthminster
Dogs are not allowed on Porthminster 10am–6pm, 15 May – 30 September. Cornwall Council lists it as “Porthminster Beach, St Ives”. The council publishes a map of the restricted area (PDF).
Outside those dates and times the council restriction does not apply, but signs on the beach and Cornwall’s other dog orders (such as picking up after your dog) still do. The council says breaking a dog order can lead to a £100 fixed penalty notice (council penalties page).

About Porthminster
The Environment Agency describes the bathing water like this:
Porthminster is on the north coast of Cornwall. It is a sandy beach resort, approximately 1.1 kilometres wide, with a gentle slope making it easily accessible.
Quoted from the Environment Agency bathing water profile, Open Government Licence v3.0. Beach material recorded by the EA: sand. Designated as a bathing water in 1988.
Safety and tides
Whether a lifeguard is on duty depends on the beach and the date. Cornwall Council says the RNLI’s main lifeguard season runs from May to September and varies from beach to beach, so check the RNLI’s lifeguarded beach finder before you go. We do not list lifeguard dates until we can check them.
The council points visitors to BBC tide tables for tide times. In an emergency at the coast, call 999 and ask for the Coastguard (HM Coastguard). More in our beach safety guide.
