If you’ve lived in Metro Vancouver for more than a week, you’ve probably heard the jokes. People call it "Rain-couver" for a reason. But here is the thing: if you head just thirty minutes southeast to Surrey, the vibe changes. Not just the traffic or the density—the actual sky.
Surrey is massive. It’s the second-largest city in BC by population, and because it stretches from the Fraser River all the way down to the U.S. border at White Rock, the weather in Surrey British Columbia is rarely just one thing. It’s a patchwork. Honestly, you can be standing in a downpour in Whalley while someone is enjoying a legitimate sun-break in South Surrey.
Why Surrey Isn't Just "Vancouver Weather"
Most people assume that if it’s raining in downtown Vancouver, it’s raining in Surrey. That is a total myth.
Vancouver is tucked right up against the North Shore mountains. Those mountains act like a giant sponge, squeezing every bit of moisture out of the clouds coming off the Pacific. Surrey is further inland and flatter. Because it’s further from those steep slopes, it actually gets less rain than places like North Vancouver or Coquitlam.
The Rain Shadow Effect
It’s subtle, but it’s real. While North Vancouver might get drenched with over 2,500mm of rain a year, Surrey usually clocks in closer to 1,400mm to 1,500mm. Still wet? Yeah. But you’ll notice more "grey but dry" days in Surrey than you will in the city.
Temperature-wise, Surrey plays by different rules. In the summer, the ocean keeps Vancouver cool. Surrey doesn't have that same immediate air conditioning. On a hot July afternoon, it’s usually 3°C to 5°C warmer in Cloverdale than it is at Kitsilano Beach. If the radio says it's 25°C in Vancouver, you better believe it’s pushing 30°C in the Fraser Valley.

Breaking Down the Four Seasons (Surrey Style)
Let’s get into the nitty-gritty of what a year actually looks like here. It’s not just "rain and not-rain."
The "Big Wet" (November to February)
November is historically the wettest month. We’re talking an average of about 223mm of rain in that month alone. This is when the Pineapple Express—a nickname for atmospheric rivers originating near Hawaii—usually hits. These storms bring heavy, warm rain that can last for days.
Winter temperatures usually hover between 1°C and 7°C. It’s rarely "Canadian cold" (sorry, Winnipeg), but the humidity makes it feel like the chill is sinking into your bones.
Wait, what about snow?
Surrey gets snow, but it’s unpredictable. One year we might get nothing but slush. The next? A freak arctic outflow brings 20cm of powder that shuts down the Port Mann Bridge. Most years, Surrey sees about 30–40cm of total snowfall, but it rarely stays on the ground for more than a few days.
The Spring Tease (March to May)
Spring in Surrey is basically a battle between cherry blossoms and sudden hail. March is notoriously fickle. One minute you’re looking at crocuses in Bear Creek Park, and the next you’re being pelted by pea-sized ice.
By May, things settle down. Temperatures climb into the mid-teens, and the rain starts to taper off. This is actually the best time for gardening in Surrey—just don't plant your tomatoes too early. The last frost usually hits in mid-to-late April.

The Secret Summer (June to August)
July and August are the "dry" months. While the rest of Canada is sweltering, Surrey is usually perfect. The average high is around 23°C to 25°C, though recent years have seen that spike significantly.
Remember the 2021 Heat Dome? Surrey hit temperatures over 40°C. While that was an extreme outlier, the trend is moving toward hotter, drier summers. August is technically the clearest month, with the sky being clear or partly cloudy about 68% of the time.
The Quick Fade (September to October)
September is arguably the best month in the city. It’s still warm (highs of 18°C-20°C), but the air is crisp. Then, October hits, and the "Great Dark" begins. The clouds move in, and the rain-boots come back out.
Microclimates: South Surrey vs. North Surrey
If you’re moving here or just visiting, location matters.
South Surrey and White Rock are often called the "Sunshine Coast" of the Lower Mainland. Because they sit on a peninsula jutting out toward the Strait of Georgia, they get way more wind but also more sun. They are often several degrees cooler in the summer and a bit milder in the winter compared to North Surrey.
Whalley and Guildford are closer to the Fraser River. In the winter, you’ll often see "river fog" rolling off the water in the mornings. It’s beautiful but makes driving on the 104 Avenue a nightmare.

Cloverdale and Clayton Heights are more "inland." They get the brunt of the summer heat and the coldest of the winter frosts. If there’s a frost warning, these areas are usually the first to see it.
What You Actually Need to Pack
Forget the umbrella.
No, seriously.
Locals don't use them as much as you think because the wind just turns them inside out.
- A high-quality shell: Think Gore-Tex or a solid DWR-coated jacket. You want something that breathes because "wet-cold" is different from "dry-cold."
- Layers: In April, you’ll start the day in a puffer jacket and end it in a t-shirt.
- Blundstones or waterproof boots: This is basically the unofficial uniform of Surrey. If your feet get wet, your day is ruined.
- Tires: If you’re driving, get M+S (Mud and Snow) or dedicated winter tires. Surrey has a lot of hills (looking at you, 10th Ave), and even 2cm of slush can turn the city into a skating rink.
The Reality of Climate Change in the Valley
We have to talk about it. The weather in Surrey British Columbia is changing. We are seeing more "Extreme Heat Emergencies" where the nighttime lows don't drop below 16°C. This is a problem because many older homes in Surrey weren't built with air conditioning.
We’re also seeing more intense "Atmospheric Rivers." The flooding in the nearby Sumas Prairie a few years ago was a wake-up call for the entire region. Surrey is investing heavily in flood protection along the Nicomekl and Serpentine rivers to handle these "1-in-100 year" storms that seem to be happening every five years now.
Actionable Tips for Navigating Surrey Weather
- Check the specific station: Don't just look at "Vancouver Weather" on your phone. Look for the Surrey East or White Rock sensors on sites like Environment Canada.
- Plan outdoor events for late July: Statistically, this is your best window for a rain-free wedding or BBQ.
- Watch the "Outflow" warnings: In winter, if you hear "Arctic Outflow," it means cold air is being pushed down the Fraser Valley from the interior. That’s when you need to wrap your pipes and bring your pets inside.
- The 4:00 PM Rule: In December, it gets dark early. Like, 4:10 PM dark. If you’re planning a hike at Tynehead or Green Timbers, get out of the woods by 3:30 PM.
Surrey weather is a bit of a chameleon. It’s wetter than the prairies, drier than the coast, and warmer than the mountains. It requires a bit of preparation, but once you figure out the microclimates, it’s one of the most livable places in the country.
Next Steps for Staying Prepared
- Download the WeatherCan app: It's the only one that uses Environment Canada’s localized radar, which is far more accurate for Surrey’s specific neighborhoods than generic international apps.
- Audit your home's drainage: Before the November rains hit, clear your gutters and ensure your perimeter drains aren't blocked by fallen leaves from Surrey’s extensive tree canopy.
- Invest in heat-mitigation: If you live in an area like Cloverdale, consider installing heat pumps or blackout curtains now, before the summer rush and price hikes hit in June.
