With snow covering most of Ottawa, this month has a low pollen count. Most Allergies in January are most likely mold or animal related. If you’re having a hard time distinguishing between a winter cold and hay fever check out our guide for a breakdown.
So long as the freezing temperatures continue in Ottawa, pollen rarely makes its presence felt this early in the year.
March welcomes spring and the start of tree pollen season. Trees blooming include Maples, Willows, Poplars, Oaks, Cedars, Hazels, Alders, Elms and Pines.
Kentucky grass is the first representative of grass pollen season caused by April’s spring showers. Tree pollen remains the dominant pollen producer in Ottawa during April.
Within May, Sycamore trees begin pollenating, along with Kentucky, Bermuda, Johnson, Orchard, and Timothy grasses, which spread pollen throughout the city.
By June, pines, birch and oaks are the main pollen producers, while sweet vernal begins to add its pollen to the other grasses.
In July, grass pollen is peaking in Ottawa while the majority of tree pollen production is coming to an end for another year.
The good news is that tree pollen production has peaked with the exception of a few late bloomers. For Ottawa, ragweed is now the dominant pollen producer, along with dock, nettle, mugwort and plantain.
Feel free to take a deep breath without a runny noses or itchy eyes as hay fever season is finally winding down with Ragweed on the decline. Let’s hope that the sun sticks around to make the most of it!
With any luck, the last of the weed pollen is on its way out, although some ragweed along with crab grass may hang around until the first frost of winter in Ottawa.
Enjoy the changing leaf colours without your eyes watering: November’s pollen count tends to be low, along with the temperature.
December brings the first official day of winter in Ottawa, which means traditionally low levels of pollen for the next few months.

Pollen Levels
The following table shows the risk level for each type of pollen derived by applying NAB guidelines to our data and taking percentile values from the extended season for each type of pollen.
Severity of pollen is dictated by the PPM number, which stands for Pollen Grains Per Cubic Metre. The weather and time of day can also be a big factor when it comes to how the pollen count can affect you. As pollen falls to the ground when the heat dissipates during the evening, this can mean your seasonal allergy symptoms get worse and is why many allergy sufferers have worse symptoms in the night. On rainy days, you’ll find your allergy symptoms are easier to manage as rain tends to wash pollen away.

Juniper
Juniper trees produce pollen grains about 20 to 30 micrometers in size (making them barely visible to the naked eye), which is small enough to become airborne and impact allergy sufferers from miles and miles away. Symptoms from juniper tree pollen allergies can include congestion, sneezing, sore throat and even dark circles under the eyes!

Ragweed
Ragweed is a weed that grows throughout Canada, especially in rural areas. A single ragweed plant can create up to 1 billion pollen grains!

If you're allergic to ragweed, you might face allergy symptoms like sneezing, runny nose, post-nasal drip and itchiness in the eyes, nose and throat. To help keep symptoms at bay, track the pollen count in your area, stay indoors during peak levels and plan ahead when you do step out.Peak Season : Late Summer -
