With each high tide, the coast of Arnside is subjected to a very fast rising tide. Because of the potential danger warning notices are posted at the pier, and an audible warning is sounded before every high tide (in daylight). The sequence of warnings is:-
# Eight sounds on the siren - around 2.25 h before high tide
# Eight sounds on the siren - around 1.75 h before high tide
# Twelve sounds on the siren - around 1.25 h before high tide, when the incoming tide is just visible from the Coastguard station (location of the siren {{coord|54.199|N|2.841|W|region:GB}} )
The cause of this fast tide is a combination of the large area of Morecambe Bay, which narrows rapidly at Arnside, plus the second highest [[tidal range]] (at [[Barrow-in-Furness]]), which can be as much as {{convert|32|ft|m}} on a [[spring tide]] nearest the spring and autumn [[equinox]]: these typically give rise to a [[tidal bore]], which may be as high as {{convert|12|in|cm}}, and is often used by canoeists.<ref>{{cite web|url=http://www.cameron-site.co.uk/nwsk/main-pages/articles/arnside_bore.htm |title=The Arnside Bore |access-date=2009-01-13 |url-status = dead|archive-url=https://web.archive.org/web/20110911153516/http://www.cameron-site.co.uk/nwsk/main-pages/articles/arnside_bore.htm |archive-date=2011-09-11 }}</ref>
