Johannesburg pollen forecast — Kew neighborhood

On 9 August 2026, overall pollen levels in Johannesburg are low. Myrtle is the main contributor to airborne pollen, while platanus, urtica, artemisia, and cypress remain at lower levels

On 10 August 2026, pollen conditions in Johannesburg will be similar to today with no significant pollen expected.

According to the five-day outlook, myrtle, platanus, oak, urtica, artemisia, and cypress pollen levels will increase later in the week.

On 9 August 2026, Myrtle is the dominant pollen source in Johannesburg. platanus, urtica, artemisia, and cypress are also present but at lower levels. oak and morus are not currently active.

Pollen at Kew builds from August as acacia and eucalyptus flower, with Highveld grass taking over through October and November. The elevated plateau's dry winter suppresses production until the spring rains arrive, and the area's government, finance, and commercial operations adds a distinctive local backdrop to the grass-dominated summer pollen season, a pattern typical of the wider Highveld region.

The Johannesburg pollen forecast is updated four times daily. See the timestamp below for the most recent update.

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.

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 Johannesburg, 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.
