Local Environmental Conditions
Around 93% of the area near this part of Sewall's Point is open water. Lawns and planted trees in a nearby park add to local grass and tree pollen. Among allergenic trees in the wider area, oak leads, followed by pecan. Grasses and pigweed growing in the surroundings are the main non-tree sources of pollen.
Tree pollen peaks in early spring, when the weather warms to around 20°C and oak and pecan are in full flower. Then come the grasses, strongest in mid-spring and fading by late fall. Later, pigweed keeps weed pollen in the air from early summer into early fall. Warm, damp weather from early summer into late winter also raises mold spore levels.

Does pollen in Sewall's Point 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 Sewall's Point 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 Sewall's Point, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
