Local Environmental Conditions
Lamberts Bay lies roughly 210 km north of Cape Town. At Lamberts Bay, native fynbos and introduced trees like oak and pine define much of the local vegetation, with denser planting in older residential streets giving way to open fynbos beyond town. Nearby fishing, farming, and small-harbour activity shapes the wider landscape feeding into the spring pollen peak, consistent with the broader Cape fynbos biome.
At Lamberts Bay, fynbos and introduced oak pollen build from August as the Cape spring begins, with grass following through September and October. The region's dry summer from December keeps pollen low, while the area's fishing, farming, and small-harbour activity shapes the mix of vegetation feeding into the spring pollen peak, a pattern typical of the broader Cape fynbos biome.

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