Local Environmental Conditions
The center of East Grand Forks sits among a blend of built-up land and open grassland. With a stream or river close by, riverside vegetation contributes to the local mix. Allergenic trees nearby include maple. Grasses are also a significant pollen source here. Around here, street trees, gardens and lawns supply most pollen in the built-up parts.
Tree pollen peaks in mid-spring, when the weather warms to around 5°C and maple is in full flower. Grass pollen follows, peaking in early summer and easing off by early fall. A smaller weed peak follows from midsummer into mid-fall. Spring is the wettest time of year, and heavy showers can bring short breaks in pollen. By late fall, as temperatures fall to around freezing, pollen levels are low again.

Are pollen levels in East Grand Forks based on measurements or forecasts?

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in East Grand Forks, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
