Local Environmental Conditions
Juazeiro anchors the São Francisco River valley on the Bahia-Pernambuco border, where native caatinga scrub, irrigated agriculture, and riparian gallery forest along the São Francisco are the main pollen sources. The very semi-arid climate produces an extremely compressed wet season, while the long dry season concentrates pollen production and the São Francisco River contributes locally significant riparian pollen throughout this northeastern São Francisco border city.
In Juazeiro, pollen exposure builds through the drier months as irrigated agriculture and riparian gallery forest along the São Francisco pollen spreads freely, while the wet season regularly interrupts dispersal with rainfall.

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