Local Environmental Conditions
Wake Forest's Wake County North Carolina suburban setting features loblolly pine, white oak, and maple as the main tree pollen sources, with exposure varying between the wooded Falls Lake watershed residential areas and the more built-up commercial corridors along US 1. Falls Lake creates significant temperature-modifying effects on the city's western portions, while the lake watershed woodland is a particularly significant local tree pollen source creating distinct lakeside-to-inland pollen gradients throughout.
Wake Forest's Research Triangle suburban setting in North Carolina produces a season opening in late January with cedar and pine before oak peaks through March and April. Grass from surrounding North Carolina farmland peaks through May and June before mugwort and nettle extend exposure into September. The Falls Lake reservoir moderates temperatures locally, while the warm Southeast Piedmont climate advances the season throughout.

When is pollen season in Wake Forest?
How often is the Wake Forest pollen forecast updated?
The Wake Forest pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Wake Forest 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 Wake Forest 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 Wake Forest, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
