The following sites are those recommended for late summer or autumn viewing. Newquay - Cornwall Storm Petrels can regularly be seen during summer evenings feeding at the sewage outfall off Newquay headland. Storm Petrels in Autumn Cornwall is primarily the best site in which to watch Storm Petrels in autumn, large numbers occurring off Porthgwarra and St Ives Island during the right conditions. The first signs of passage begin in late July, but from early August to mid September, birds can be seen almost daily, especially from Gwennap Head, Porthgwarra. These same conditions will see similar numbers passing Pendeen Watchpoint, but these will always be distant.
Evenings are best.
An alternative method for seeing Storm Petrels is to attend one of the regular ringing sessions held on the east coast throughout July.
