Every spring, giant chunks of Arctic and Greenlandic ice drift south along "Iceberg Alley," passing right by the coast of Newfoundland before slowly melting in the North Atlantic. St. John's is one of the best-positioned cities in the world to see this natural spectacle up close, and if you time your visit right, you can pair iceberg watching with a whale-watching tour on the very same boat. Here's what to know before you go.
Iceberg season generally runs from late April through June, with many visitors considering May the sweet spot for the highest concentration of bergs visible near shore. The exact timing shifts year to year depending on wind, currents, and how much ice calved off Greenland's glaciers the previous year, so it's worth checking local sighting reports as your travel dates approach.
You don't always need a boat to spot an iceberg—several coastal viewpoints around the city and along the Avalon offer excellent shore-based views on a clear day.
For a fuller list of stops worth building into your itinerary, our St. John's visitor guide covers the wider area beyond iceberg watching too.
Late spring into summer also brings humpback and minke whales to the waters off the Avalon Peninsula, drawn by capelin schools close to shore. This overlap means a single boat tour in May or June can realistically deliver both icebergs and whales in the same outing—one of the reasons the region draws wildlife watchers from around the world.
Several operators run boat tours departing from St. John's harbour and nearby communities like Bay Bulls, taking visitors out for a closer look at both icebergs and marine life. Tours vary by operator, so it's worth booking ahead during peak season and confirming what's currently visible on the water, since conditions change quickly.
Many visitors find May offers the best balance of iceberg numbers and milder weather, though the season can start earlier or run later depending on conditions each year.
Yes—shore-based lookouts like Cape Spear, Signal Hill, and Middle Cove Beach often offer clear views of passing icebergs on a good day, no boat required.
Often, yes. Because whale season overlaps with the tail end of iceberg season, many boat tours departing St. John's and nearby Bay Bulls combine both in a single trip during May and June.
