Local Environmental Conditions
This area, a short distance from here, has mangroves dominate the water's edge, typical of this area's brackish, low-lying coastal waterways. Here, in the vicinity, tree cover made up mostly of slash pine and cabbage palm, typical of this area's flatwoods. The general pattern described here holds fairly steady across nearby areas with similar land cover.
August is this area's warmest month at around 29°C, cooling to about 21°C by January, and of the 1532 mm that falls here annually, most arrives in the warmer stretch around August. Expect pollen activity to start building from around February, tracking the rise in temperature out of the January low.

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