Pollen counts are up and running In Cape Town, Johannesburg, Bloemfontein and Durban and strong differences have emerged between the four regions. High tree pollen counts Tree pollen counts are high in Cape Town and Johannesburg. Cypress tree is the dominant pollen in Cape Town while Plane tree pollen is the most abundant pollen in […]

The fungal spore load increased slightly but remained low throughout this sampling week. Tree pollen concentrations remained high owing to the contribution of cypress pollen. Pine, gum and poplar tree pollen was seen in low numbers. Grass and weed levels were very low.
5 August 2019
Despite torrential rain and very low temperatures, cypress tree pollen concentrations increased during this sampling week. Grass and weed pollen was low and fungal spore loads were very slight.
29 July 2019
The tree pollen levels increased sharply as high counts were recorded for cypress. Pine, willow, mulberry, and gum pollen was seen. Grass pollen levels were very low and no weed pollen was seen in this cold and rainy sampling week. Fungal spore levels were low with small surges in the basidiospore (mushroom) and asocospores loads […]

Fungal spore loads were light but there was a small significant spike for Pleospora, the wet weather spore when a concentration of 442 spores/cu M was recorded on 16 July. Tree, weed and grass pollen levels were low, but on warmer days between rain and cold days, tree pollen increased as pine and cypress trees […]
15 July 2019
Fungal spore levels returned to low levels during this sampling week of rain, mist and low temperatures. Very low pollen levels were seen throughout the week, but occasional grains of tree pollen appeared occasionally.
8 July 2019
The fungal spore load increased to moderate levels during this sampling period as ascospores reached moderate level on sunny days, following rain. Small but insignificant spikes were seen for basidiospores and Cladosporium. Pollen in the air was extremely scarce but the first Betula (birch tree) grain was seen.
1 July 2019
Tree, weed and grass pollen levels were extremely low during this sampling week of copious rain and low temperatures. Fungal spore loads were also low, but increased over the previous week as ascospores and Cladosporium concentrations showed small but insignificant spikes during sunny periods.
24 June 2019
Extremely low fungal spore loads and pollen levels were seen throughout this sampling week of low temperatures and heavy rain at times.
