Local Environmental Conditions
Around 46% of the area near this location in Cape Hatteras is open water, with some wetland and built-up land. With much of the immediate area made up of open water, local pollen production is limited, though pollen can still drift in from surrounding land.
Tree pollen comes first, peaking in early spring. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. In warm, humid weather from late spring into mid-fall, mold spores add to the mix, especially after rain. By midwinter, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Cape Hatteras come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Cape Hatteras based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Cape Hatteras, 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.
