Local Environmental Conditions
River oak grows along the bank here, releasing fine wind-borne pollen typical of casuarina species, close by. This area, in the vicinity, has green space with maintained lawn and planted plane trees, both contributing to seasonal pollen counts. Local microclimate and soil conditions can push these figures slightly higher or lower.
Along the waterway, river oak releases pollen first, reaching its high point sometime in late winter or early spring. As spring turns to summer, grass pollen rises toward its November high, before pollen counts gradually decline through January and February. The overall order of species tends to hold steady, even as exact dates shift slightly each year.

How often is the Jamestown pollen forecast updated?
The Jamestown pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Jamestown 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 Jamestown 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 Jamestown, 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. |
