What to wear whale watching in Tromso: the layers that make the day

On a RIB you wear the operator’s suit. It is a full-body thermal flotation suit: you step into it over your own clothes at the base, zip it to the chin, pull up the hood, and add the boots and gloves they hand you. It is bulky, it is warm, and it floats. Inside it your own clothing does one job only, which is to insulate; the suit handles wind and spray entirely. Listings at $340, $244 and $260 all work this way.

On a catamaran or a larger boat you wear your own clothes and step inside when you want to. $223 and $211 run heated indoor seating with open decks outside it; $212 has a heated saloon; $218 has indoor lounges and outdoor decks; $266 includes suits as part of its all-inclusive fare. Here your layers do all the work while you are on deck, which is where you will want to be whenever a blow goes up.

Our top pick, the full day north at $361, includes the transfer from Tromsø and the suit for the boat, so the only decision left is what goes underneath.

Base: merino wool, top and bottom. Cotton holds moisture against the skin and turns cold the moment you stop moving, which on a twelve-hour day happens often. Merino keeps insulating while damp and it handles a full day of wear well. Thermal leggings under normal trousers are the single most effective thing most visitors add.

Mid: fleece or light down. This is the adjustable layer. In a heated saloon it comes off; back on deck it goes on. A hooded fleece is more useful than a hoodless one because the hood fills the gap between hat and collar when the boat is at speed.

Outer: a proper winter jacket with a hood, plus windproof trousers. On the big boats this is your shield. Waterproof matters more than it sounds: the deck picks up spray, and snow on a moving boat arrives horizontally. On a RIB the operator’s suit replaces this layer entirely, so pack for the walk to the quay instead.

The failure people describe afterwards is almost always the same, and it is rarely the coat. It is thin socks in tight boots, bare wrists between glove and sleeve, or a hat that covers the head while leaving the ears out. Those three gaps cost more comfort on a whale watching Tromso day than any jacket gains.

Two things happen in Arctic air. Batteries lose capacity quickly, and warm glass fogs when you carry it from a heated saloon into a headwind. Both are easy to manage once you expect them.

Keep spare batteries in an inside pocket against your body and swap them in rather than waiting for a full one to die. Leave the camera in the cold between sightings instead of shuttling it inside and out, which is what causes condensation on the lens. On a RIB, a wrist strap is worth more than a neck strap: gloved hands and a moving boat are a combination that rewards being tethered.

And a small point that improves most people’s photographs more than any lens: the light on a whale watching Tromso trip is low and sideways all season. Underexposing slightly keeps the pink in the snow and stops a black dorsal fin turning into a silhouette against bright water. The guides on the silent boats often say the same thing while the engines are off.

The fjords on a whale watching Tromso route are sheltered by islands for much of the way, and many trips stay inside that shelter. Crossings can still roll, and the honest approach is to prepare rather than hope.

Take a tablet with breakfast rather than on the boat: the common remedies work best taken an hour or two before departure, and taking one on a calm day costs nothing. Eat something plain beforehand, because an empty stomach fares worse than a full one. Once aboard, sit in the middle of the boat where the motion is least, keep your eyes on the horizon or on the mountains, and stay on deck in the fresh air if you feel unsettled — the warm saloon is comfortable and the open rail is steadier for your inner ear.

Crews carry bags and are entirely unbothered about handing one over. The larger boats at $223 and $212 have the most stable platforms and real toilets; a RIB is livelier by design and best suited to people who enjoy that.
