Local Environmental Conditions
Delfzijl's urban greenery relies mainly on oak, birch, and linden, which dominate local tree pollen output, though the gap between centre and edge can be considerable depending on wind direction. Given Delfzijl's standing as an estuary industrial port town, the Eems estuary and Wadden Sea coast and nearby Groningen farmland add noticeably to grass and tree pollen levels.
Pollen exposure in Delfzijl gets underway in January courtesy of hazel and alder, climbs to a birch high point around April, and lasts until August. April and May bring oak and ash into the mix, before grass becomes the main source through the following two months. the Eems estuary and Wadden Sea coast has a bearing on how quickly pollen disperses, and the chemical-industry sea port is a notable part of life around Delfzijl.

When is pollen season in Delfzijl?
How often is the Delfzijl pollen forecast updated?
The Delfzijl pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Delfzijl 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 Delfzijl 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 Delfzijl, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
