Track the Ottawa pollen count for the next few days using the tracker. Your Pollen Pal gives you a pollen forecast in any location across the city so you can head out to Rideau Canal or Parliament Hill safe in the knowledge that you are lowering your chances of having hay fever symptoms.
Trees produce pollen in Ottawa from March until July. Ottawa’s most common tree allergens are Alder, Ash, Birch, and Poplar trees1. Grass pollen is in the air from April until July as well, followed by weed pollen. Ragweed pollen is the dominant strain in Ottawa, beginning in August through September (or until cooler temperatures take over.)
Canada’s capital city might be buried under snow for a good part of the year but when spring comes, life blooms again across Ottawa. Unfortunately, so does pollen. Events like the Spring Tulip Festival in May might be allergy inducing due to pollen peaks. Even the popular Rideau Canal may need to be avoided at high pollen times. Check the pollen forecast to plan your trip and keep reading to find alternative activities for those hay fever inducing days.
Just because its hay fever season doesn’t mean you need to hide away. There are plenty of activities in and around Ottawa that can be enjoyed, pollen or no pollen. If you do want to head out into green spaces, it’s worth noting when Ottawa’s low pollen seasons are.
Naturally, as the capital of Canada, Ottawa has a plethora of important buildings to visit and explore. Of course, during grass pollen season, you may have to stick to the indoor tours of Parliament Hill, as it is surrounded by fields of grass. Check Your Pollen Pal for the pollen forecast so you know before you go.
Long cold winters mean that much of the shopping in Ottawa is indoors and therefore pollen free all year round!
Brush up on your trivia by visiting any of Ottawa’s many museums.
