Past Reports

Summary The highest tree counts with a large variety in species occurred in Bloemfontein where the dominant trees were false olive, or butterfly bush, plane, white stinkwood, birch and pine....

Summary The tree flowering season is in full swing now especially in Johannesburg and Bloemfontein. Dominant trees are plane, mulberry, white stinkwood, oak, olive and false olive. Grasses, weeds and...

Summary Tree pollen is now high or moderate at all the inland sites and rising at coastal sites. The allergenic trees: Plane, oak, cypress and olive are at the peak...

Summary Tree pollen is reaching high concentrations in Bloemfontein and Johannesburg. Coastal sites have higher tree loads but have just begun their flowering cycle, so the concentrations are still low...

Summary Tree pollen is increasing rapidly inland as the trees begin their spring flowering cycle. The pollen of plane, oak, olive, mulberry and cypress is already significant in Johannesburg, Pretoria...

Summary Very low temperatures with frost, rain and snow in some areas continue to inhibit the release of pollen and moulds. Despite this, spring trees are stirring and cypress pollen...

Summary The bitterly cold weather at most of these sampling sites has persisted, with frost at night and snow on high lying ground in some regions. Cypress is now seen...

Summary The continued rain, low temperatures and frost has reduced all pollen and mould loads in the air. Spring tree pollen is seen on days with sun but the concentrations...

Summary During this midwinter period with low temperatures, heavy, rain, floods and snow, extremely low pollen and mould concentrations were recorded. Cape Town The spore trap could not be changed...

Summary All sampling sites in South Africa reflected the effects of the low temperatures, rain, frost and snow and pollen and mould concentrations were minimal. Cape Town From a waterlogged...

Summary Pollen and mould concentrations were low at all the listed sites. The Johannesburg sampling site has come back into operation from this week. Cape Town Pollen and mould concentrations...

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...
