Local Environmental Conditions
The heart of Jaraguá do Sul is surrounded mainly by built-up land, with some woodland. With the Itapocu River nearby, riverside vegetation along its banks contributes to the local mix. In the immediate area, street trees, parks and lawns are the main sources in the built-up parts. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Tree pollen comes first, peaking in early spring. Grasses take over in mid-spring, with temperatures around 20°C, and their pollen lingers into early fall. Weeds on open ground add a smaller late peak from early summer into early fall. In warm, humid weather from early spring into late fall, mold spores add to the mix, especially after rain.

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