Summary Pollen and fungal spore concentrations remain low at all the sampled sites except subtropical Durban, where fungal spores were moderate and in Potchefstroom where significant spikes for the allergenic...

Summary Pollen and fungal spore (mould) concentrations were flat in all cities except Potchefstroom, where mould spores were moderate, in response to rain and low temperatures. Cape Town Pollen in...

Summary Low temperatures and rain removed pollen and fungal spores from the atmosphere and this can be seen in the low figures. The only elevated scores were seen in Potchefstroom...

Summary Pollen counts were low at all sites. A surge in the allergenic mould spore Cladosporium was seen in Durban where a record daily high of >17 000 spores/cubic metre...

Summary Grass, tree and weed pollen counts plummeted at all the sampled sites. Moulds were equally low,  as rain and low temperatures negatively affected the pollen catch and fungal load....

Summary Tree, grass and weed pollen counts were low at most sites. A small spike for weeds occurred in Johannesburg and fungal spore loads were moderate in Pretoria. Cape Town...

Summary Pollen counts were low at all sampling sites with spikes for weeds in Potchefstroom, where significant ragweed counts were recorded and Johannesburg, where mugwort counts were moderate. Cape Town...

Summary Moderate grass counts were found in Potchefstroom. A significant concentration of ragweed pollen was detected at that site as well as spikes for Alternaria, Epicoccum and Cladosporium, all allergenic...

        Summary Grass pollen is high in Pretoria and Potchefstroom. Elevated weed counts were detected in Potchestroom and mould spores were moderate in Durban, Kimberley and Potchefstroom....

Summary Grasses were moderate in Pretoria and high in Potchefstroom.  A strong spike for the allergenic mould, Cladosporium was seen in Potchefstroom. Cape Town Pollen concentrations were very low during...

Summary There is a moderate risk for grass pollen allergy in Pretoria and Bloemfontein and mould spores were significant in Durban and Pretoria. Cape Town Pollen in the atmosphere was...

Summary Grass pollen is increasing in some summer rainfall regions of South Africa. Increased grass levels were seen in Johannesburg, Pretoria and Kimberley. Tree and weed pollen levels are generally...

Summary Grass pollen increased to moderate levels in Pretoria, Kimberley and Potchefstroom.  Most grass pollen was released in the cooler mornings in Kimberley as the maximum temperatures reached 40ºC, inhibiting...

Summary Loadshedding at all the sampling sites will have reduced these counts. Pollen was low in most sampling areas except for Potchefstroom, where weeds increased the mean count and Durban,...

Summary Torrential rain occurred at many of these sites. In cities where rain was prolonged (Johannesburg) pollen and mould was washed from the air so low counts were seen. In...

Summary The hot, dry weather conditions at most of the South African sampling sites resulted in very low pollen and mould or fungal spores in the atmosphere. The exceptions were...

Summary Low pollen loads were found from all the sites in the South African Pollen Monitoring network (SAPNET) this week. Ragweed (Ambrosia spp.) was detected from the air of Durban,...
