September 2025 Forecasts and Discussions

good point Stuffy. The cool nights and decreased daylight hours offset any major heat we may get this time of year, like now. It is now September! So nice and cool this morning..the house wont be stifling hot later.
On a side note, the Similkameeeens is facing a sever water shortage in some areas, with the wells literally running dry for many so i know we are all hoping for a heavy snowpack this winter in the southern Interior

Smoky and gunky this morning.

We're stuck with this for another week with no real westerly push or rain to get this smog/smoke out of here.

On top of that, there’s the smoke to consider. It limits daytime heating much more than it inhibits nighttime radiational cooling.

on a "duller" note, starting this weekend EC says enjoy the showers and cool down

[AbbyJr]

Warm and humid here with slightly reduced air quality.

[Rubus_Leucodermis]

Air quality is now in the high 200’s headed to 300 (unhealthy heading into hazardous) here

Special Air Quality Statement in effect for:

Metro Vancouver - SE

Smoke is causing or expected to cause poor air quality and reduced visibility.

(September 3, 2025) Metro Vancouver Regional District has issued an Air Quality Warning in Metro Vancouver and the Fraser Valley due to elevated fine particulate matter (small particles in the air that may impact health).

This warning is expected to last for a few days or until there is a change in weather.

Cause: Metro Vancouver and the Fraser Valley are experiencing hazy conditions due to wildfire smoke. Wildfires contributing smoke to the region include those just east of Hope, near Whistler, and a large complex of fires in the Cariboo region, in addition to fires in the US.

Smoke concentrations may vary widely across the region as winds, temperatures, and wildfire behaviour changes.

As smoke levels increase, health risks increase. Limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events.

You may experience mild and common symptoms such as eye, nose and throat irritation, headaches or a mild cough. More serious but less common symptoms include wheezing, chest pains or severe cough. If you think you are having a medical emergency, seek immediate medical assistance.

People more likely to be impacted by outdoor air pollution, including people aged 65 and older, pregnant people, infants and young children, people with an existing illness or chronic health condition, and people who work outdoors, should reduce or reschedule strenuous activities outdoors and seek medical attention if experiencing symptoms.

When indoors, keep windows and doors closed as much as possible. When there is an extreme heat event occurring with poor air quality, prioritize keeping cool.

Protect your indoor air from wildfire smoke. Actions can include using a clean, good quality air filter in your ventilation system and/or a certified portable air cleaner that can filter fine particles.

If you must spend time outdoors, a well-constructed, well-fitting and properly worn respirator type mask (such as a NIOSH-certified N95 or equivalent respirator) can reduce your exposure to the fine particles in the smoke. Even though exposure may be reduced, there can still be risks to health.

Check in on others who are in your care or live nearby who may be more likely to be impacted by outdoor air pollution.

Always follow guidance from local authorities.

September record for the highest dew point in Vancouver with 19.8°C.

It's very humid here. I'm at 27.1C and 58% humidity with a dew point of 18.1C.

[Typeing3]

Currently 29c with smoke. All surface level stuff and not aloft which is the bad type.

Fairly muggy too.

[Hawk]

Rather smoky in Langley today too. Felt kind of warm out there, but nothing extreme.

Almost certainly there is enough smoke in the air today to make us measurably cooler.

Not here. It's currently 30.5C with 45% humidity and a dew point of 17.2C. While there is definitely smoke in the air, I don't think it's having much if any impact on the temps. There is still some blue sky visible and it doesn't even smell that smokey here. Sounds like it's worse further west.
