Past Reports

Summary The low temperatures with snow on high lying ground have reduced pollen and moulds in the air. Low concentrations of early flowering trees like cypress were seen in low...

Summary At all the pollen sampling sites across South Africa, pollen and mould concentrations were very low in response to the low temperatures and rain, in this early winter period....

Summary Low winter temperature and rain have reduced the pollen and fungal spore (mould) loads in the air to very small amounts. There is a low risk for allergy to...

The latest report is delayed but will be posted today. Summary Pollen concentrations are low but the early flowering tree, cypress, is appearing in the air at many sites, indicating...

Summary Pollen concentrations are low during this early winter period, but moulds are fluctuating and the allergenic moulds like Cladosporium increase rapidly when rain is followed by sunshine. Cape Town...

Summary Grass was moderate in Kimberley and moulds, notably the allergenic mould Cladosporium, were moderate in Durban and Potchefstroom. Cape Town Pollen and mould concentrations were extremely low. Trees detected...

Summary Grass peaks persist in Kimberley and Bloemfontein and are just significant in Potchefstroom. Tree, weed and mould concentrations are low throughout the pollen sampling network. Cape Town Insignificant pollen...

Summary Grass concentrations show peaks in Bloemfontein and Kimberley where concentrations are high and in Potchefstroom moderate grass concentrations were seen. The ragweed peak in Potchefstroom continues. Cape Town Insignificant...

Summary Unusually high grass counts were seen in the Kimberley, Bloemfontein and Potchefstroom for most days of the sampled week and significant ragweed counts were recorded in Potchefstroom. Cape Town...

Summary Significant ragweed concentrations were detected in Potchefstroom. Moderate grass concentrations were seen in Pretoria and Kimberley and Cladosporium peaks occurred at several sites in response to the cool and...

Summary Pollen concentrations were low at all sites except Potchefstroom where the weed concentration increased. The dominant weed was ragweed. Moulds were significant in Durban. An interesting tree pollen found...

Summary Tree, grass and weed concentrations were low throughout South Africa, except for moderate grass pollen in Gqeberha. Moulds were high in Potchefstroom, moderate in Durban and Gqeberha. Cape Town...

Summary Moulds are high in Durban and grasses are moderate in Pretoria, but pollen counts in most of the sampled cities are now low. Cape Town Trees usually seen at...

Summary Pollen in the tree and weed categories remains low, but moderate grass concentrations are seen in Kimberley and Durban. Moulds increased during this autumn period especially in Durban, Kimberley...

Summary The public holiday on 21 March made it impossible for aerobiologists to read the pollen strips. Four-year means are given for most of the sites, Grasses are usually moderate...

Summary Pollen and fungal spores are all below the significant threshold but small peaks for trees (waxberry and elm) or little spikes for fungal spores/moulds were seen in Kimberley, Durban,...

Summary Mid-autumn weather reduced pollen and fungal spores in the ambient air of most of the sites. Summer rainfall areas may have moderate counts for grass as was seen in...

Summary Grasses in all the coastal cities in this pollen network were insignificant, while inland cities all had significant grass concentrations. Weeds and trees have completed their major flowering cycle....

Summary Moderate (>5 grains/cubicmetre grass concentrations were found in Bloemfontein, Kimberley and Potchefstroom. Archived data 2020-2023 indicate that moderate grass counts would be found in Johannesburg at this time of...

Summary: Grasses are significant in Gauteng, Kimberley and Bloemfontein (more than 5/cubic meter). Cape Town High temperatures and strong southerly wind reduced pollen and moulds in the air at this...

Summary Grasses are high (more than 20 grains/cubic meter) in Kimberley and moderate (more than 5 grains/cubic meter) in Johannesburg, Potchefstroom and Bloemfontein.      Cape Town Tree, grass and weeds...

Summary Significant grass concentrations were found in Kimberley and Bloemfontein and grasses in Pretoria and Johannesburg are likely to be high. Ragweed was detected at the Durban and Kimberley sites....

Summary Grass pollen is increasing in several summer rainfall regions. Tree pollen was moderate in Bloemfontein and spikes were seen for elm in Potchefstroom. In Durban, ragweed is appearing and...

 Pollen Alerts Grasses have increased in Gauteng, Eastern Cape, Bloemfontein and Durban and may pose a risk to grass sensitive individuals. Moulds/fungal spores are high in Durban and George. Cape...
