Local Environmental Conditions
Around 62% of the area near the center of St Lucia is woodland, with some open water. So much tree cover makes trees an important source of pollen locally. Grasses also feature strongly, alongside pigweed among the weeds. Clearings, tracks and woodland edges let grasses and other flowering plants grow among the trees.
Temperatures stay between about 20°C and 25°C through the year, so plants release pollen in most months. The drier stretch around June to August usually brings the most pollen. During the rainy season, frequent heavy downpours wash much of the pollen out of the air. Warm, damp weather from early spring into mid-fall also raises mold spore levels.

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