Snámh
Ireland's sea swimming almanac
$4.99 · Designed for iPad. Not verified for macOS.
Irish Sea temperature, tides, water quality and council notices for 270+ Irish swim spots, scored live for your level. Know before you get in. Snamh
Snámh is the sea-swimming almanac for Ireland. Before you drive to the beach, it tells you what the water is doing right now: sea temperature, waves and swell, wind direction and gusts, tide flow, rain risk, EPA water quality and any council notice in force. One score out of 100, weighted for your own level, tells you whether it is a morning for a long swim or a quick dip.
EVERY SWIM SPOT, ONE SCREEN
• 270+ monitored bathing waters across the whole island, from the Forty Foot to Keem Bay, plus tidal pools, coves and lakes.
• Live sea temperature, feels-like, waves, swell period, wind force, and whether it is blowing onshore or offshore.
• EPA water quality classification, the latest sampling results and four years of history.
• Official council bathing notices and prior warnings, pushed to your phone as soon as they are issued.
• Met Éireann weather warnings, air quality and river levels where they matter.
PLAN AROUND THE TIDE
• Next high and low, range, and a 30-day tide curve from the Marine Institute.
• Hour-by-hour scores through the day and the best two-hour window.
• Sunrise, sunset, first and last light, golden hour and moon phase.
• 7, 10 and 16-day outlooks.
SCORED FOR YOU
• Tell Snámh how experienced you are and how much cold you can take, and every score adjusts.
• Seven activities: swimming, paddling, surfing, wind sports, beach day, walking and photography.
• Safety problems cap the score. A red warning or a Poor water rating can never hide behind good weather.
YOUR SPOTS
• A watchlist with live verdicts, a home beach, and alerts when a flag changes or a notice lands.
• Home Screen and Lock Screen widgets, plus Siri Shortcuts.
• Filters for lifeguards, Blue Flag, toilets, parking, kid-friendly beaches and more.
• Add your own quiet spot.
EVERY DIP, REMEMBERED
• Track a swim with GPS distance, pace and calories, follow it as a Live Activity on your Lock Screen, and save it to Apple Health as an open-water workout.
• Or log a dip by hand with the water temperature and a note.
• Charts of dips by month and water temperature through the year.
• Journal and watchlist sync between your devices with iCloud.
APPLE WATCH
• Conditions, forecast, tides and safety notes on your wrist.
• Track a swim from the watch with heart rate and Water Lock.
• Complications showing the sea temperature and today's verdict for your spot.
BUILT FOR IRELAND
• Data from the EPA, DAERA in Northern Ireland, Met Éireann, the Marine Institute and Open-Meteo.
• Works offline with a saved copy of the last conditions.
• No account needed. Sign in with Apple is optional, for sync only.
Snámh gives guidance, not guarantees. Conditions change fast, so always check the water, the flags and your own limits before you get in.
