Tides & CurrentsReading Tides in Southeast Alaska
Tidal swings of 18–20 feet are common in Lynn Canal and Stephens Passage. A beach that looks calm at high water can become a raging tidal rapid two hours later. Learn how to read tide tables, identify tidal constrictions, and time your paddles to work with — not against — the water.
- Always check NOAA tide predictions for the nearest reference station before launching
- Add 1–2 hours of buffer around slack water for any significant tidal constriction
- Tidal currents in narrow passages like Seymour Canal can exceed 4 knots — scout before committing
- Ebb tides in Lynn Canal run south; flood tides run north — use them for free miles
Open WaterCrossing Open Water Safely
Open crossings in Southeast Alaska expose you to wind, chop, and cold water with no bailout options. Lynn Canal, Chatham Strait, and Stephens Passage can build steep, confused seas quickly. Know how to assess conditions, pick your window, and execute a crossing with a plan.
- Check NOAA marine forecasts (Zone AKZ035–AKZ041) the night before and morning of any crossing
- Winds above 15 knots on open water mean wait — Southeast chop is steep and close together
- Paddle crossings in the early morning before afternoon thermal winds build
- Always have a bailout plan: identify the nearest downwind shore before you leave
Cold Water SafetyCold Water & Hypothermia
Water temperatures in Southeast Alaska range from 38°F to 52°F year-round. Immersion incapacitates most paddlers within minutes. A dry suit is not optional — it is the minimum standard for paddling these waters. Understand the cold shock response, swimming failure, and how to self-rescue.
- Dress for immersion, not air temperature — a dry suit is essential, not optional
- Cold shock can cause involuntary gasping and hyperventilation within seconds of immersion
- Practice wet exits and re-entries in controlled conditions before paddling remote water
- Paddle with a buddy whenever possible — solo paddling in cold water is high-stakes
NavigationNavigation & Route Planning
Cell service is nonexistent across most of Southeast Alaska's coastline. Paper charts, a compass, and the ability to read the land are essential skills. GPS is a useful backup — not a primary tool. Learn to identify landmarks, track your position, and navigate in fog.
- Carry NOAA nautical charts (paper) for every area you paddle — chart 17300 covers most of Southeast
- A baseplate compass and the ability to take bearings is a non-negotiable skill
- Fog is common — know your compass bearing to the nearest safe shore before it rolls in
- VHF radio (Channel 16) is your emergency lifeline — carry one and know how to use it
WildlifePaddling Around Wildlife
Southeast Alaska is home to humpback whales, orcas, Steller sea lions, brown and black bears, and Dall's porpoise. Most encounters are magical — a few require careful handling. Know the rules, keep your distance, and never let excitement override judgment.
- Federal law requires 100 yards minimum distance from humpback whales — 200 yards from orcas
- If a whale surfaces near your kayak, stop paddling and let it move away on its own
- Sea lions are curious and can be aggressive — give haul-outs a wide berth
- Never approach a bear on the beach — back-paddle quietly and give it space
GearEssential Gear for Southeast Alaska
The right gear makes the difference between a great trip and a survival situation. Southeast Alaska's weather changes fast — sun to sideways rain in 20 minutes is normal. Pack for the worst day you might encounter, not the best day you hope for.
- Dry suit + wool or synthetic base layers — no exceptions for multi-day trips
- Bilge pump, paddle float, and tow line should be on your deck, not buried in a hatch
- Waterproof VHF radio, EPIRB or PLB, and a signal mirror for emergencies
- Bring more food than you think you need — weather can pin you down for days
