The first time I went out on a whale watching cruise in Kaikōura, I wore a light jacket and trainers. By the time we found the first sperm whale — about forty minutes offshore — my fingers were numb, my shoes were soaked from a wave that caught the bow, and I was trying to photograph a whale tail with hands that could barely operate my camera. The whale was extraordinary. My preparation was not.
The second time, I wore three layers, waterproof boots, and packed everything in a dry bag. I stood on the upper deck for the full two hours, watched two sperm whales, and came back warmer than when I left. The difference between a good Kaikōura whale watching trip and a great one is almost entirely preparation. This guide covers everything you need to bring — and a few things you should leave behind.
TL;DR
- Dress for the ocean, not the shore. The water six kilometres offshore runs 6–8°C colder than town, before wind chill and sea spray — so a windproof, waterproof jacket with a hood is non-negotiable in every season.
- Layer up, protect against sun, and prepare for motion sickness in advance. Warm mid-layer, waterproof footwear, SPF50+, polarised sunglasses and tablets taken 45–60 minutes before boarding.
- Keep it compact and dry. A small daypack and a dry bag for your phone, camera and valuables — storage on board is limited and spray gets everywhere.
The Core Principle: Dress for the Ocean, Not the Shore
This is the single most important piece of advice, and the one most visitors ignore. The temperature on the water is not the temperature in town. On a calm, sunny Kaikōura morning in January when the thermometer reads 22°C and you are walking the Esplanade in a t-shirt, the ocean six kilometres offshore will be at least 6–8°C colder — and that is before the wind chill that builds as the boat reaches cruising speed. Add sea spray, and the effective temperature drops again.
Locals who work the boats dress in the same layers whether it is July or February. The rule is simple: dress as if it is colder and windier than you expect, then bring one more layer. You can always take it off. You cannot conjure a jacket from thin air when you are six kilometres offshore in a sea breeze.
Everything below is calibrated to the standard Kaikōura whale watching cruise — roughly three hours all up, just over two of them on the open water. If you have not booked yet, this is the tour these tips are written for:
Clothing: The Essential Layers
- A windproof, waterproof outer shell (with a hood). Not a light shower jacket — a genuine waterproof with sealed seams. The boat moves fast, spray comes from unexpected angles, and a hood is the one thing most people regret not bringing when spray hits the face at full wind.
- A warm mid-layer. A fleece, light down jacket or heavy knit under the shell. Two thin mid-layers beat one thick one — you can adjust as conditions change through the trip.
- A thermal base layer. Essential April–October; even in summer a light long-sleeved thermal keeps your core stable across two-plus hours on the water.
- Waterproof footwear with grip. Trainers are the most common footwear mistake — the deck gets wet and wet trainers stay cold all trip. Rubber-soled boots also grip a wet deck. If you only have trainers, wear your warmest socks.
- A warm hat and light gloves. Your hands need to be functional to work a camera. A beanie and thin liner gloves make an enormous difference — in summer too.
- A dry change of clothes left in the car or a locker at the whale watch centre. You may not need it, but you will be very glad it is there if you do.
Sun Protection
You can be cold and sunburnt at the same time on the ocean. UV reflects off the water surface, the boat deck sits above the shoreline shade, and the trip is long — even on an overcast day, UV penetrates cloud. Pack all three of these:
- Sunscreen SPF50+, water resistant. Apply before you board, not on the boat, and reapply after two hours. Do not forget the tops of the ears.
- Polarised sunglasses with a strap. Polarised lenses cut the surface glare that makes spotting and photographing wildlife harder; a retention cord stops them going overboard.
- A brimmed hat or cap. Under your hood when the wind is up, on its own when it is calm.
Photography Gear
Most people come with a camera in mind, and a little preparation dramatically improves the results.
- Camera or phone. Modern smartphones produce excellent daylight results. A mirrorless or DSLR with optical zoom (200mm equivalent or longer) captures detail at the respectful distance the boat keeps under New Zealand's Marine Mammals Protection Regulations.
- Shutter speed matters most. A sperm whale's fluke shot is over in under four seconds. Use a fast shutter (at least 1/1000s in bright light) and burst mode — you will take fifteen frames of the tail and one will be the keeper.
- Protect your gear. Sea spray is salt water. Keep the camera in a dry bag between sightings and pack a microfibre cloth for the lens.
- Spare battery and memory. Cold drains batteries — keep a charged spare in an inside pocket — and a whale watch fills a card fast.
Motion Sickness Prevention
This is the section that makes or breaks the trip for a surprising number of people, and the one most often left until too late. The waters around Kaikōura can be choppy. The catamaran handles swell better than a monohull, but it is still a boat on the open ocean.
- Medication is the most reliable option. Tablets such as dimenhydrinate or meclizine must be taken 30–60 minutes before boarding. Once you feel sick, it is too late. Buy your own supply at a pharmacy in Kaikōura or Christchurch the day before so you take it at the right time.
- Acupressure wristbands (Sea-Bands) help some people and pair well with tablets for mild susceptibility.
- Choose a morning departure. Seas are calmest at dawn before the wind and swell build — the single most practical prevention there is.
- On the boat: stay on deck with fresh air and eyes on the horizon, sit amidships where the boat moves least, don't read or look at your phone, and eat something light beforehand.
- Ginger — in tablet, sweet or tea form — has genuine evidence behind it as a natural supplement.
If you know you are prone to seasickness, the swell-free alternative is the scenic whale watching flight: 30 minutes in the air, no motion, and a unique top-down view of the whales and the canyon. It is the smart choice for anyone who dreads a rough sea state:
Food, Drink & Other Essentials
- Water and light snacks. A sealed water bottle and a muesli bar or crackers. Keep it light — heavy or greasy food and an active sea do not mix. Skip strong-smelling hot food; save the crayfish for after.
- A dry bag. Phone, wallet, passport and snacks all go inside a dry bag or ziplock — spray is surprisingly penetrating.
- A compact daypack (10–20L). Storage on board is limited; leave the wheeled luggage behind.
- Regular prescription medication. The tour is 3+ hours and waits for no one once offshore.
- For young children (ages 3+): small-size warm layers, familiar snacks, and the option of the warm indoor cabin for a break from the deck.
Leave behind: wheeled or hard-shell luggage, expensive jewellery, fragile souvenirs, and umbrellas (useless and hazardous in wind — your hooded jacket is all the rain protection you need).
Season-by-Season Adjustments
- Summer (Nov–Mar): waterproof jacket still essential, light mid-layer, and prioritise sun protection as much as warmth. Optional light gloves for early departures.
- Autumn/Spring (Mar–May, Sep–Oct): full waterproof shell, warm mid-layer, thermal base layer, hat, gloves and waterproof boots. Sunscreen still essential — UV doesn't follow the temperature down.
- Winter (Jun–Aug): everything above, doubled — non-negotiable thermal base, two mid-layers, winter-weight gloves, waterproof boots, and a neck gaiter or balaclava.
