Local Environmental Conditions
Bald cypress and red maple line the water's edge, common along this area's clear spring runs, close by. Located close by, this area has a nearby park's turf and ornamental trees layer grass and ragweed pollen onto the seasonal mix. As with most local readings, actual levels can vary somewhat with short-term weather swings.
July is this area's warmest month at around 29°C, cooling to about 16°C by January, and annual rainfall here totals about 1182 mm, concentrated mostly in the warmer months around July. From around February onward, pollen activity tends to pick up here, tracking the rise out of the January temperature low.

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