Many people in Newfoundland and Labrador would argue that there isn't such thing as Spring here. Through March, April and May you still see a lot of snow, but like elsewhere, the nature is waking up from a long winter so you will start to see more greenery around. Spring is the time when hikers start getting out for their first hikes (without snowshoes) of the new year.
West Coast is generally warmer because it is not directly exposed to the Northern Atlantic Ocean. Now that the skiing season is over, you will start to see less snow and more greenery around.
Thanks to its distance from the ocean, Central Newfoundland in spring is slightly colder but drier.
Labrador's weather is generally colder than Newfoundland's, and even in spring you will still get quite cold temperatures.
Newfoundland and Labrador during Summer is the place to be. Through June, July, and August, you will get the highest temperatures of the year. It is also the time of whales coming by the shores, jumping alongside icebergs floating just off the coast. It's a great time for hiking and exploring on foot and participating in the many festivities happening all around the island. You will not get any extreme temperatures, thanks to the marine climate preventing high temperature differences that you would find in drier climates.
Summer on the West Coast is beautiful, just like everywhere else in the province. With the ocean temperatures reaching over 15°C, you can even get out for a swim. And the fogs usually stay away, unlike in St. John's and the Avalon.
Central Newfoundland in the summer is drier, so the summers are more consistent than on the East Coast (Avalon). You will enjoy a nice and mild summer.
The weather in Labrador is short, but very pleasant. With the average high temperatures reaching 18°C, you can get out and enjoy the beautiful surroundings.
Though summer is the warmest time, autumn is some people's favourite. Through September, October, and November, you still get pleasant temperatures, so it's the perfect time to go exploring the changing nature, where leaves start turning shades of orange, red, and yellow and hillsides full of rock faces are lit up by yellow grass—what a sight! Many corn mazes are put up throughout the province, and Halloween decorations are a fun sight during this time of the year.
The West Coast of Newfoundland, around Corner Brook, is known for its beauty during the fall, and it's one of the best times to see Newfoundland. With mild temperatures, it's still a great time to get out and hike.
During the fall, you will get to see some amazing colours around central Newfoundland.
September in Labrador still reaches an average high of 12°C, but then it goes down rather rapidly to -4°C being the average high for November.
Thanks to the marine climate, the temperatures during the Newfoundland winter don't go as low as in other parts of Canada. Labrador is considerably colder, though. There are many things to enjoy during winter. Newfoundland and Labrador is a great place to enjoy skiing and snowboarding. Locals also love snowmobiling, so you will find many enthusiasts everywhere during the winter.
On the West Coast of Newfoundland, you can find incredible plains of powdered snow to ride to hit a backcountry snowboarding trail. And you can also catch snowboarding at the biggest ski resort in Newfoundland and Labrador, Marble Mountain.
Because of the drier climate, you tend to find better snow conditions than on the Avalon. There is also a ski resort in Central Newfoundland called White Hills in Clarenville.
Winter in Labrador does get quite chilly. However, because of drier snow, you will get more powdered snow and better conditions for snowboarding and snowmobiling. Labrador also has a Smoky Mountain Ski Club in Labrador City.
