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.

“With such levels of accuracy, we can predict the pollen count on your street for up to five days ahead.” Madhusudhan Anand, Co-Founder & CTO of Ambee

Pollen is a light airborne dust that acts as a fertilizing agent for various plants. Trees, flowers, grass, and weeds all produce pollen, especially during the spring and summer months.

Similar to how the Air Quality Health Index measures pollution in the air, the pollen count is the measure of how much pollen is in the air on a given day. This information is gathered from reporting stations across the country to provide accurate local pollen readings.

It’s not uncommon to think you’ve caught a cold or flu when you actually have allergies. Sometimes referred as hay fever, tree pollen allergies may cause these symptomsnasal congestion; sinus pressure; runny nose; itchy, watery, red eyes; coughing; scratchy throat; postnasal drip; and fatigue1.

In a word, yes. A study presented at the 249th National Meeting & Exposition of the American Chemical Society (ACS) reported that a pair of air pollutants linked to climate change interact with certain pollens resulting in a change at a chemical level which increases the pollen’s potency. This in turn provokes a more powerful immune response from allergy sufferers.3

Pollen counts are highest on dry, windy days and lower after rainfall or at night – and usually peak between 5 a.m. and 10 a.m. and again at dusk, so avoid these times if you plan to be outdoors. If you plan to exercise outside during allergy season, consider wearing a face mask designed to filter out pollens. As soon as you get home, rinse out your nose with saline or ask your doctor about nose sprays to provide relief.

A tree pollen level above 50 is considered high, while one to 10 is considered low. Be sure to check your local pollen count before venturing outside and plan accordingly.
