Local Environmental Conditions
Sandton's northern Johannesburg affluent suburban setting features jacaranda, plane, and indigenous bushveld trees as the main pollen sources, with exposure varying between the extensively tree-lined residential neighborhoods and the more built-up Sandton City commercial corridor. The Braamfontein Spruit corridor is a particularly significant local source, while the dense residential tree canopy makes Sandton one of the more significant tree pollen locations in the Johannesburg metropolitan area.
Sandton's affluent northern Johannesburg setting produces a season opening in August with jacaranda and plane before grass from surrounding Highveld grassland and residential lawns peaks through October and November. The jacaranda flowering in October is a particularly iconic and locally significant tree pollen event, while the dense residential tree canopy makes spring tree pollen particularly significant throughout the season.

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