Local Environmental Conditions
Around 37% of the area near this location in Mossel Bay is built-up land, with a good deal of open grassland and some woodland. Of the trees nearby, olive is the one that matters most for allergies. Grasses and weeds such as pigweed and plantain round out the local mix.
Olive leads the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in late spring and keep pollen in the air into early fall. The season closes with pigweed and plantain from early summer into early fall. Dry, sunny and breezy weather raises levels within each period, and steady rain brings them down.

Does pollen in Mossel 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 Mossel 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 Mossel 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.
