Summary Grass levels continue to be at significant in the summer rainfall areas of South Africa and are currently the highest in Kimberley, Pretoria and Bloemfontein. Very little tree pollen was detected across all the sampling sites. Weed pollen was also scarce but the autumn flowering weeds are appearing. Moulds increased in Durban and Gqeberha, […]

Summary A new monitoring site was added to the South African Pollen Monitoring Network: Calvinia in the Northern Cape. Grass and fungal spore counts were high in the summer rainfall areas, with Pretoria having the highest grass count in the country and the highest fungal spore levels were found in Kimberley. Tree and weed pollen […]

Summary Grass levels continue to be significant in the summer rainfall cities of Johannesburg, Pretoria and Kimberley. Tree pollen remained low across the country and weed counts approached significance only in Pretoria and Bloemfontein. Pretoria and Durban both had significant fungal spore levels. Cape Town Grass counts were insignificant. Tree pollen included the sumac or […]
25 February 2022
Summary Durban had very high fungal spore counts. Grass pollen counts have decreased across the country, but moderate levels are still present in the summer rainfall areas. Weed and tree counts were generally low, with weeds increasing to moderate levels in Cape Town. Cape Town Grass and tree pollen counts were low, with weed pollen […]

Summary Grass levels remain significant in the summer rainfall areas, with very high counts recorded in Kimberley. Tree pollen counts approached significance in Cape Town and the weed pollen in Bloemfontein was also above the moderate threshold. Mould counts likely remained high in Durban (no new data) and peaks for the allergenic spores, Cladosporium and […]

Summary Grass levels have decreased across the country, as moderate counts were only seen in Kimberley and Bloemfontein during this sampling period. Tree pollen was moderate in Cape Town and Durban, while moderate weed counts were detected in Cape Town and Bloemfontein. Fungal spore counts in Durban continue to be significant. Cape Town Grass counts […]

Summary Fungal spore levels remain high in Kimberley and Durban, with spikes of allergenic spores present. Grass counts were moderate in Pretoria, Kimberley and likely Bloemfontein (no new data), but low elsewhere. Tree counts approached significance in Cape Town and Durban. Cape Town Grass and weed pollen counts were low, and tree pollen levels were […]
8 April 2022
Summary Significant grass levels were seen in Bloemfontein and on sunny days in Kimberley, where frequent rain removed some pollen from the air. A greater variety of tree pollen was detected in Cape Town during this sampling period, but tree and weed levels were generally low at all the sites. High mould (fungal spore) concentrations […]
7 January 2022
Summary Pollen in the atmosphere is sparse at most sites. Grass pollen is increasing in summer rainfall areas and significant levels have been recorded in Bloemfontein. Tree pollen was not significant at any of the sites during this sampling period, but weed pollen is increasing. Moulds were generally low but significant levels were detected in […]
