May vs June Alaska Cruises: Which Month

May offers fewer crowds, lower availability of services, cooler temperatures, and potential snowfall in ports, but provides longer daylight hours and opportunities to see wildlife emerging from winter. June features warmer weather, fuller bloom of wildflowers, peak wildlife viewing including whales and bears, more operational shore excursions, and increased cruise departures, though with larger crowds and higher demand for accommodations.

Weather and What to Actually Expect

Let’s talk weather without the cruise brochure fluff. May in Alaska is technically spring but don’t pack your sundresses just yet. You’ll experience what locals call “breakup season” when winter loosens its grip. This means temperatures hover in the mid-40s to mid-50s and you might see snow flurries in ports like Skagway or Juneau. The upside? Those dramatic snow-capped mountains look absolutely incredible against moody skies.

June brings Alaska’s version of summer. Temperatures climb into the 50s and 60s and you’ll actually want to sit outside on deck without looking like the Michelin Man. The landscape transforms from winter brown to vibrant green as wildflowers explode across hillsides. Rain is still possible in both months because this is a temperate rainforest after all, but June tends to be slightly drier.

Wildlife Viewing Showdown

Here’s where it gets interesting and why wildlife photographers often prefer May despite the chillier conditions.

May Wildlife Advantages

• Humpback whales are actively feeding after migration and easier to spot
• Sea lions congregate in large groups before dispersing
• Migratory birds arrive in massive numbers
• Mountain goats are more visible at lower elevations
• Bears are just emerging from hibernation and concentrated near shorelines

June Wildlife Advantages

• Salmon begin their runs bringing bears to streams and rivers
• Bear cubs are more active and visible
• Whale watching remains excellent with multiple species present
• Puffins and other seabirds are nesting
• Wildflower blooms attract diverse wildlife

The truth? Both months deliver spectacular wildlife viewing. If whales are your priority, May edges ahead slightly. If you want that iconic shot of a bear catching salmon, late June is when the action begins heating up. Learn more about June Alaska cruise opportunities for peak wildlife season.

Pricing and Value Considerations

Money talks and May definitely speaks a friendlier language to your wallet. Cruise fares in May can run 20-30% lower than June pricing because it’s considered shoulder season. But here’s what cruise lines won’t advertise: some shore excursions and attractions don’t open until late May or early June.

That helicopter glacier tour you’ve been dreaming about? Some operators start limited schedules in mid-May. The famous White Pass Railroad in Skagway typically runs reduced frequency early in the season. Certain hiking trails remain snow-covered or muddy in May.

June brings full operational status to nearly everything but you’ll pay premium prices for both the cruise and excursions. Popular tours sell out faster and you’ll compete with more passengers for restaurant reservations and spa appointments onboard.

Port Experience Differences

The port experience shifts noticeably between these two months. In May, you’ll find some shops and restaurants still ramping up for season. Small towns like Haines or Sitka feel more authentic with fewer tourists crowding Main Street. You can actually have a conversation with locals without feeling rushed.

June ports buzz with energy. Everything is open, street performers entertain crowds, and that famous salmon bake everyone talks about is operating at full capacity. The trade-off is that popular attractions can feel overrun. Five ships might dock in Juneau on the same day creating congestion at Mendenhall Glacier.

Insider Port Tips

• May passengers should research which attractions operate on limited schedules
• Book May shore excursions directly with operators who often offer early season discounts
• June cruisers need to pre-book excursions months in advance for popular activities
• Both months offer excellent opportunities for independent exploration

Daylight Hours and Photography

Alaska’s extended daylight is a game-changer for cruise passengers. May delivers 17-19 hours of daylight depending on your latitude. June pushes that to 18-20 hours with some areas experiencing near-constant twilight. For photographers this means golden hour lasts forever and you can shoot landscapes at 10 PM.

The quality of light differs too. May’s lower sun angle creates dramatic shadows and that moody atmosphere Instagram loves. June’s higher sun provides brighter more consistent lighting but can wash out midday shots. Both months occasionally treat you to the Northern Lights though your chances decrease as summer solstice approaches.

Onboard Atmosphere

Ship vibe varies between these months more than you’d expect. May cruises attract an older demographic of retirees, serious photographers, and travelers who prioritize value over peak conditions. The pace feels more relaxed with easier access to popular venues and activities.

June brings families on summer vacation, creating a livelier atmosphere with more children onboard. Evening shows pack out and you’ll need reservations for specialty restaurants. The energy level increases but so does the noise and competition for prime deck space during scenic cruising.

Wondering about how June compares to July cruising? The differences continue as summer progresses.

Practical Packing Differences

May requires serious layering. Pack thermal underwear, a heavy fleece, waterproof jacket, warm gloves, and a winter hat. Yes really. That glacier viewing from the deck gets cold and wind chill matters. Waterproof hiking boots are essential for shore excursions.

June allows lighter packing but still demands layers. You’ll use that fleece pullover and waterproof jacket but can skip the winter gear. A light down vest works well for evening deck time. Comfortable walking shoes suffice for most ports though waterproof options remain smart.

Both months require rain gear because Alaska precipitation doesn’t check calendars. Bring a compact umbrella and waterproof bags for electronics and cameras.

Shore Excursion Availability

This aspect catches many first-time Alaska cruisers by surprise. May operates on partial schedules for many activities. Some wilderness lodges don’t open until late May. Certain hiking trails need snow clearing. Kayaking outfitters may run reduced tours.

The flip side? May excursions feel more intimate with smaller groups. You’ll have the glacier practically to yourself in photos without hordes of tourists in the background.

June brings full operations but also maximum crowds. Every excursion runs and new seasonal offerings launch. Fishing charters, bear viewing flights, and multi-activity tours operate at peak capacity. Book early or risk disappointment.

Common Questions and FAQ

Can I see the Northern Lights on a May or June Alaska cruise?

Your odds are extremely low for both months due to extended daylight hours. May offers slightly better chances than June particularly in early May when darkness still occurs. However, Alaska Northern Lights season peaks from September through March when you have actual nighttime. If aurora viewing is a priority, Alaska cruising isn’t the right choice regardless of month.

Do inside passage waters get rough in May versus June?

May can experience rougher conditions as spring weather patterns remain unsettled. The Inside Passage itself stays relatively calm due to protection from islands, but open water segments like the Gulf of Alaska can get bumpy. June typically offers calmer seas though weather never comes with guarantees. If you’re prone to seasickness, pack medication for either month.

Will I need formal attire for May cruises versus June?

Formal night policies depend on cruise line and ship rather than month. Most Alaska cruises feature “cruise elegant” rather than formal attire. May and June cruises follow identical dress code policies. However, May passengers tend to dress more casually overall while June brings more families who skip formal nights entirely. Check your specific cruise line’s current policies.

Are flights to Alaska cheaper in May or June?

May flights typically cost less since it’s before peak summer travel season. June prices jump as school lets out and family travel surges. Booking flights for either month several months ahead provides the best rates. Consider flying into Seattle or Vancouver and taking an Alaskan cruise from there rather than flying directly to Alaska for better flight options and pricing.

Do glaciers look different in May versus June?

Yes, subtly but noticeably. May glaciers show more snow coverage creating dramatic blue-white contrast. June’s warmer temperatures increase glacial melt producing more active calving events and waterfalls. Photographers debate which looks better but both months showcase glaciers beautifully. The quality of light matters more than the month for glacier photography.

Can I swim in the ship’s pool during May Alaska cruises?

Most Alaska cruise ships feature heated pools and hot tubs that operate year-round. You can absolutely swim in May though you’ll want to hop between the hot tub and pool quickly. The air temperature makes lounging poolside less appealing in May versus June. Covered pools and indoor facilities see heavier use during cooler May weather.

Personal Experience

I spent weeks agonizing over whether to book our Alaska cruise for May or June, and honestly, the decision came down to what mattered most to us as a family. May offered better prices – we’re talking several hundred dollars less per person – but the weather can be unpredictable with more rain and cooler temperatures. June, on the other hand, promised longer daylight hours (hello, nearly 20 hours of sun!) and warmer weather in the 60s, which seemed perfect for spending time on deck. The cruise line rep mentioned that both months are fantastic for wildlife, though May edges ahead slightly for whale watching as humpbacks are actively feeding, while June brings out more bears along the shore as salmon start running.

We ended up choosing June because traveling with kids meant we wanted the most comfortable weather possible, and those extra hours of daylight were a huge selling point for maximizing our port days. Sure, we paid a bit more, but not having to bundle up in heavy winter gear and being able to enjoy outdoor activities without constant drizzle felt worth it. That said, my sister went in May last year and had an incredible time – she saw tons of whales and saved enough money to splurge on a helicopter glacier tour. Really, both months have their perks, and it just depends on whether you prioritize your budget or peak summer conditions.
