North Channel Swim Conditions

 

The North Channel is also referred to as the North Irish Channel and is a stand alone swim and also is a part of the Ocean Sevens series.

Swim windows

The North (Irish) Channel has shorter and substancially less tidal windows than those of other channels across the globe.

In some swim windows there are only five days within which a North Channel swim attempt can take place.  Other swim windows extend up to eight or nine days.  

Swim windows for the North Channel are usually on a neap tides occuring between June and September.  Outside of this the daylight hours are less and the waters are much cooler which do not make for pleasant swimming conditions.

Distance, tides and currents

The shortest distance across the North (Irish) Channel in a straight line is 34.5 Kilometers. 

All official North(Irish) Channel swims take place within Admarality Chart 2198

All official North (Irish) Channel swims adhere to Irish Long Distance Swimming Association North Channel rules.  

There are other channels of water outside of this area including the Dál Riata Channel.

A North (Irish) Channel crossing may commence in either Scotland or Ireland and the history of the North (Irish) Channel as maintianed by Irish Long Distance Swimming Association records successful swims from both sides.

Whilst the swim progresses East through West or vice versa the tide runs North to South in 6 hour ebb and 6 hour flood cycles. With strong tidal currents your swim may cover up to 45 Kilometers. Your swim line will track North or South whilst advancing Easterly / Westerly depending on your swim speed, tidal flow and weather conditions.

In training for your North (Irish) Channel attempt you should get experience of swimming across currents and not just with or against the tide.  In the fina lapproaches to landfall be mindful that the currents and tidal force will push you back.  You need an extra swim gear for this.

As the tidal flow changes, your swim start time may be in the hours of darkness.  In training for your North (Irish) Channel attempt be sure to practice swimming in the dark, swim with friends for support, have a kayaker chaperone you and also get used to wearing an adventure light https://infinitychannelswimming.com/product/infinity-adventure-lights-guardian-expedition/ or a glowstick on the back of your goggles or swim costume.

Water temperature

Water temperature ranges between 11°C  and 15°C with some evidence of 15°C  to 16°C  later in the season.

Part of the North (Irish) Channel swim crosses  over the Beaufort's Dyke where temperatures can drop to around 11°C to 12°C.

Some previously recorded water temperatres and buoy markers are detailed at the bottom of this page.

In training for your North (Irish) Channel attempt, after your qualifification swim you should continue to gain exposure to colder waters. If where you are from you are not able to achieve this easily as the sea / lakes or rivers are too warm, take advantage of cold showers, ice baths, no swim cap and maybe ice cold drinks during your swims.  These are all important parts of you being prepared for the elements on swim day. 

Weather

The weather on the North (Irish) Channel can change quite quickly often regardless of what the weather forecasts have predicted. In days of modern technology we all have access to advanced Apps which tell us of the wind, weather etc.  

infinity Channel Swimming  will decide on your swim date and communicate with you in the days leading up to your North Channel attempt.  Allow us to worry about Mother Nature and give yourself and your crew important time to focus on being rested and ready.

Wild life

The North (Irish) Channel has revealed a fabulous array of wildlife indicating healthy, clean waters including Dolphins, Minke Whales, Orca, lots of Seaguls who come and rest a while beside you and Seals.  The only other debris being seagrass and seaweed.  

Oh ! and the jellyfish!

Aurelia aurita (also called the common jellyfish, moon jellyfish, moon jelly or saucer jelly)

There are of course plenty of lion's mane jellyfish and it would not be the North (Irish) Channel without them.

Other sea life and views

The North (Irish)hannel is not a bus Cy shipping area.  The Stena ferry crosses and there are a minimal number of vessels and sailing craft.

There are a few reference points:

Dunskey Castle https://www.visitscotland.com/info/see-do/dunskey-castle-p255821  

The coastline is fabulous, steep cliff faces, some small sandy beaches and green fields galore and of course an ever changing sea state.   

 

Nutrition and hydration

In days of old we have referenced the legend Kevin Murphy who enjoyed pork pies and chicken legs on his North (Irish) Channel crossings.  Oceans Seven legend Lynton Mortenson knows of the benefits of a warm cup of MILO hot chocolate and Queenof the North (Irish) Channel Caroline Block will vouch for her bespoke swim nutrition and essential mild mouth wash to stave of the salt tongue.

What ever your feed of choice be sure it is tried and tested. There are a world of options out there for carbohydrate, protein and essetial nutrient and electrolyte nutrition including UCAN, SiS,  CNP, Tailwind, High 5, SPONSER etc, etc.  weh have seen them all.  Find yours.  It may be as simple COMPLAN but regardless if it works it works.

Realise the movement of the tide / sea and how this may impact on your tummy / digestion. Again - practice !

Seak specialist advice from a Sports Dietitian who has experience of long distance swimming nutriton especially relating to how cold water impacts on the digestive tract and on your feed absorption.  With the addage - don't try anything new on race day - have a plan written down and if its working in training stick with it.  A few tweeks here and there can make a difference.  Make sure your crew know it inside out and know how to hlep if there needs to be some tweets made.  eg: reducing feed times to every 20 minutes if you get colder, incresing feed times if you are advancing well,  Have a treat box it may include  a chocloate roll, a jaffa cake, some chocolateeven some jelly sweets, small things you can look forward to and enjoy with your mainly liquid diet.

Practice feeding and in an precise way,  the tide moves fast, if you stop to fed for 2 minutes you can lose up to 300m distance - over 12 feeds thats a lot more swimming you have to do!.

Learn to feed from a bottle atached to a feeding line, see how you be fast to grab someting from a feed tray and pocket it in the side of your mouth to enjoy between feeds.  These skills all take time to learn, practice and know the benefits of.  

Flat coke can also be a good item to have in your kit box - it can settle an upset tummy.  

Definatley consider and if we can be specific opt in for warmed feeds.  Quick reiminder here of the temperature of the North channel - a warm feed is a saviour.  

Talk to other channel swimmers and see what they recommend.

Pharmacy

Antiemetics , AntihistaminesGrease / Desitin / Sunscreen  / Vaseline, Arnica for bruising, etc etc.  Speak to your pahrmacist an get what suits you.  Remember your crew also - they may not be used to life on a boat and don't yet have their sea legs.  

Finally,

Again this is all only advice - none of it is exact science (well maybe the sealife is) but it is from the heart and it is based on our experiencs of the North (Irish) Channel to date.  We want you to have a successful crossing, so from practice at night swimming to getting the feed right we want you to come here prepared and ready to be successful.
