Summer in Vancouver is glorious. Everyone's out at the beach, or boating, or hiking in the parks, or playing beach volleyball, going out camping, exploring the local islands, sitting on restaurant patios and just soaking up the rare sunshine. Summer can start as early as June and last until late September, although statistically July, August and early September are the warmest, driest months.
Although temperatures are often in the 20's Celsius (70's-80's F), it rarely goes above. It's never humid and the temperatures drop into the teens Celsius (50's-60's F) at night. Air conditioning is unnecessary. If you're outside in the evening, you will definitely want to wear a light jacket or a hoodie. Also remember, it's cooler by the water and warmer inland.
During the day people are in shorts, t-shirts, skirts, skimpy summer dresses, swimsuits, and sandals. Of course, there are days when it's cloudy, overcast and (gasp!) rainy. So do bring some jeans and some light jackets to wear on those days.
We call autumn "fall" in Vancouver. It's somewhat of a non-event in Vancouver when compared to elsewhere in Canada because our trees are evergreen and don't change colour, but it still occurs from mid-September to mid-November. This is actually a very dry and sunny time to be in Vancouver. September is still very summery and warm - temperatures in the high teens and 20's Celsius (65-75 degrees F), but it gets down to the single digits Celsius (40's F) by November.
People start putting away their summer clothes by late September, swapping shorts and sandals for jeans, long sleeves, and closed toe shoes. Jackets are often light or wool - lots of emphasis on new fall fashion styles which are often about earth tones. People start wearing sweaters (jumpers) and wool coats. Gloves and scarves might be worn when it's chilly. By late October Vancouver's famous rainy season kicks in, so expect a lot of gloomy grey skies.
Mid-November to mid-February is winter in Vancouver. That's when it's dark, dreary, wet, and cold. Temperatures are around the 0 to 7 degrees Celsius range (30's to 40's F). It'll always be colder inland or in the mountains and warmer closer to the water.
You will definitely want a warm coat. I make do with a wool coat, gloves and a scarf. Some people wear GoreTex jackets with fleece lining. Parkas are unnecessary. Many people like to wear a toque (sounds like "tuke") which is the Canadian word for a woolen winter cap. I generally wear jeans throughout the winter, although if it goes below freezing, sometimes it's nice to wear a pair of tights underneath. A closed toe shoe (with socks) should be worn in the winter - bonus if they won't get soaked in the rain. You'd be crazy to wear open toe stilletos or sandals. Only a few hardcore joggers wear shorts in the winter. Long sleeved shirts and sweaters (jumpers) are practical, although a lot of locals like to wear t-shirts with hoodies over top.
Spring comes early to Vancouver in late February and lasts until late June. This is a beautiful time in Vancouver as there's a sweet smell in the air, the flowers are in bloom, the gardens are lush, the daylight is longer, and people are outdoors.
Spring temperatures are best described as mild, usually hovering between 10 to 20 degrees Celsius (50's and 60's degrees F) and sometimes it's even warmer. Rain still falls, but not in large quantities. People break out the light jackets, the hoodies, or just go out in jeans and t-shirts during the day. Winter coats, gloves, and scarves are no more but you'll still want a jacket, especially in the evenings. Closed toe shoes are still common, but sandals are starting to emerge on dry, warmer days. There's a mix of short and long sleeves. It's still a tad early for tank tops, skirts, shorts, and summer dresses, however they're much more common by May and June. Sometimes during a warm spell, people can be out sunbathing on the beaches in swimsuits.
Luggage and bags:
Clothing/Shoes/Weather Gear: Warm clothing in early September, walking shoes (no high heeled shoes, please!) and jackets!
Toiletries and Medical Supplies: Not that I know of!
Photo Equipment: Cameras that are tied to your arms to avoid them from falling down below the river!%
Camping/Beach/Outdoor Gear: This does not apply
You can buy anything here. So if you find that you have too much or too little clothing things are easily solved...with a little shopping. I'd suggest that you bring a heavier jacket during the winter it doesn't get as cold here as the east...but for those who aren't used to cold weather..make sure to have at least a sweater.
In the summer particularly June-August....it gets pretty warm, but not that hot. Temperatures are between 20C-30C. But during the night you should have a light jacket...just in case it gets a little chilly. It is very acceptable here to wear mini-skirts, tank tops...etc.
In the fall...temperatures start to fall...especially around Nov it can get to 0C....but don't let that ward you off from coming here. I'd have to say that Winter here is just as pretty in the Summer. If you do come here during the winter...it would be wise to go up to whistler....very beautiful up there. I always look forward to going there every year during my Winter Break.
Photo Equipment: It's a must...for all the beautiful scenary around here in the west coast.You can buy cameras here....not too expensive. If your camera breaks down you shouldn't worry too much....you can easily get it repaired. Don't worry about film you can buy it practically anywhere.
Luggage and bags:
Don't go overboard, but pack enough warm clothes that will help you get through the cold and keep you nice and toasty inside.
Summer, just like Seattle, it rains. So take a rain jacket or umbrella.
Clothing/Shoes/Weather Gear: Bring walking shoes. There's lot to see in Downtown Vancouver. I hope you are prepared to taste great seafood. Since, Vancouver is close to the water they get the freshest seafood..Yum!
Toiletries and Medical Supplies: If you are planning to hike or ski just make sure you bring the usual aid needed for small cuts what not.
Photo Equipment: Canadian currency to US is less, so you can defenitely get more for your money here and anywhere in Canada. Plus, if you buy anything worth over $50 you can get the tax refunded.
Vancouver's geography -- mountains and ocean --mean the weather is constantly changing. People talk about the weather all the time, but you can't control it, so it's best to be prepared. The problem in Vancouver is that we have the 'four seasons in a day' syndrome, something that you find in other coastal towns and cities with similar topography.
My recommendation is that you bring light layers -- no bulky stuff, but at least something to protect you from wind and rain, even in the summer. Within minutes the temperature can drop or climb, and only by layering can you deal with the changes without too much hassle. Also, if you're like me and prone to losing umbrellas and find it's a pain to carry around, then a hooded jacket is much more low-maintenance.
Clothing/Shoes/Weather Gear: The climate seems to be much like the Oregon/Washington coastal areas. Being farther north, you might expect it to be colder, but it was mild when we were there. From looking at all the flowers, I'd say it stays mild all summer.
Miscellaneous: My experience with some Japanese students, who studying English whom I met here is that in the summer time, they find that in the night time it is cold so I think that whenever you go out in the night time please bring extra jacket.
Dress in layers - the climate is similar to the Uk. It can be warm one second and cold the next (or raining).
Waterproofs (or an umbrella) are a must just in case of an impromptu cloudburst.
In winter, unbrella and raincoat.
Toiletries and Medical Supplies: UV suntan lotion for hot hot summers.
for me,Antacid tablets to counter gastranomic overindulgences.
Photo Equipment: the full gear to record the scenery
