Local Environmental Conditions
This part of New York is densely built up. With the East River nearby, riverside trees such as willow, poplar and alder along its banks contribute to the local mix. The allergenic tree mix nearby includes oak, plane tree and maple. Mugwort and pigweed are the main local weed pollen sources. Oak is unusually common here compared with most other locations, making it a particularly important local pollen source.
Oak, plane tree and maple lead the season in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. The season closes with mugwort and pigweed from midsummer into early fall. The oak period in late spring is usually the most intense time of year here. Warm, damp weather from early summer into early fall also raises mold spore levels.

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