Local Environmental Conditions
River oak lines the bank, contributing some of the season's more persistent wind-borne pollen, not far from here. A park whose lawns and ornamental plane trees quietly add to local pollen levels; this sits in the vicinity. Local wind exposure and land use can shift the exact mix slightly from block to block.
River oak along the water gets the season underway before other species, usually the first pollen source active, peaking sometime in July or August. Grass pollen rises through spring toward a November high point, holding through the summer months before tapering off by late February. Warmer or wetter years can pull these peaks a week or two earlier or later.

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