Is September Right for You?
Weigh the advantages and considerations before booking
- + September is the sweet spot in St. John's. The summer crowds that pack George Street and the Signal Hill trails through July and August have thinned out by the second week. Walk the North Head Trail along the cliffs above the harbour narrows without queuing for the good photo spots. Same-week tables open at the long-standing seafood rooms on Water Street that were booked solid a month earlier.
- + The light is the thing locals quietly love about September. Slanting afternoon sun sets the Jellybean Row houses on Gower and Prescott Streets glowing in their candy reds, yellows and blues. Long golden evenings over the harbour are far easier to photograph than the flat midsummer glare. Fog still rolls in off the Atlantic. But it tends to burn back by late morning more reliably than in June.
- + Whale-and-seabird boat tours and East Coast Trail hiking are both still running in early-to-mid September. Cooler air, often 14 to 18 degrees C, roughly 57 to 64 degrees F, makes cliff-top walking far more comfortable than sweating up Signal Hill in August. Humpbacks linger in the bays into the first weeks of the month before the season winds down.
- + Prices ease noticeably after Labour Day. Downtown guesthouses and the heritage inns around Military Road and Gower Street drop from peak-summer rates. Flights into St. John's International (YYT) soften. The whole town moves at a friendlier, less harried pace once the cruise-season rush tapers off.
- − Post-tropical storms are the real September risk in Newfoundland. The tail ends of Atlantic hurricanes regularly track up to the island in September. A single system can bring a full day of horizontal rain and 80-plus km/h (50-plus mph) wind that cancels every boat tour and grounds the ferry to Bell Island. Build a flexible day or two into any short itinerary.
- − Daylight and warmth are both shrinking fast. By late September the evenings turn cool, dropping toward 14 degrees C (57 degrees F) or lower with a damp wind off the water that feels colder than the number suggests. The 28 degrees C (82 degrees F) warm spells the data hints at are the exception, not the rule, and they rarely last more than a day.
- − Some seasonal operators start closing for the year. Smaller boat-tour outfits in Bay Bulls and a handful of Quidi Vidi-area food and craft spots scale back hours or shut entirely after mid-month. so the later in September you visit, the more you should confirm a place is still running before you build your day around it.
Best Activities in September
Top things to do during your visit
Signal Hill is where Marconi received the first transatlantic wireless signal in 1901. The path that matters is the North Head Trail dropping from Cabot Tower down the cliff face to The Battery, a cluster of fishermen's houses clinging to the rock at the harbour mouth. September is good for this. Cool, dry air means you climb without overheating. Crowds that clog the boardwalk in August are gone. Low-angle sun lights the harbour narrows beautifully in late afternoon. You will hear the foghorn, smell the salt and kelp, and feel the wind try to take your hat. Roughly 1.7 km (1.1 miles) one way, steep and rocky in places.
Early September is the tail of the humpback season in the bays south of the city. Boats out of Bay Bulls run toward the Witless Bay Ecological Reserve, where you may still catch feeding humpbacks breaching close to the hull. Cool spray hits your face and the diesel-and-brine smell of the deck is under you. Numbers drop as the month goes on, so this is firmly an early-to-mid September activity. Lighter crowds mean smaller, calmer boats.
Cape Spear is the easternmost point of North America, about 15 km (9.3 miles) southeast of downtown. Standing at the railing with the next landfall being Ireland is the kind of moment that justifies the windswept drive. September clears out the summer tour buses, and the autumn light on the old 1836 lighthouse (the oldest surviving in Newfoundland) is superb. Bring a windbreaker because the gusts here are relentless and the temperature at the point often feels several degrees colder than in town.
Quidi Vidi is a tiny working fishing village tucked into a rocky cove minutes from downtown. Dories still bob beside weathered fishing stages and the smell of salt cod and woodsmoke hangs in the cool air. The local brewery here is famous for a beer chilled with iceberg-sourced water. September's calmer pace means you can sit by the gut and watch the boats rather than jostling through summer crowds. Pair it with the artisan studios along the waterfront.
The East Coast Trail stitches together over 300 km (186 miles) of raw Atlantic coastline, and the segments near St. John's, the dramatic Spout route and the cliffs toward Blackhead, hit their stride in September. Bog and barrens flame into rust-red and gold. Partridgeberries ripen right beside the path. Cooler air makes the relentless up-and-down feel almost gentle. You will hear only wind, surf, and gulls. Trails turn slick and exposed in wind. Always check the day's forecast.
George Street crams the highest concentration of pubs and bars per square foot in North America into two short downtown blocks. It is the automatic rainy-day and post-hurricane fallback when boats and trails shut down. You can slip into the smaller rooms and hear traditional Newfoundland music, the fiddle and accordion sets locals turn out for. Ask about a Screech-in. The tongue-in-cheek ceremony makes you an honorary Newfoundlander with a shot of rum and a kiss of the cod.
