Past Reports

Tree pollen increased in Johannesburg, Bloemfontein, Pretoria and Potchefstroom. Rain diminished the pollen concentrations in Cape Town. The dominant trees are plane, mulberry, olive, ash, and African stinkwood. Grasses, weeds...

High tree pollen concentrations were seen at several sites and the dominant tree was plane, followed by cypress, beech and mulberry. Cape Town Grasses were generally low but on the...

Tree pollen is high at many sites and plane tree is now the dominant pollen. The Cape grass season has started early (27 August) after heavy winter rainfall in this...

Tree counts were moderate to high at most SA sampling sites and the dominate tree pollen was cypress. Cape Town Rain removed pollen and fungal spores from the atmosphere during...

Tree pollen has increased to moderate or high levels at most of the sites and the dominant tree is cypress. Grasses and weeds were very low. Cape Town Repeat of...

Tree pollen is increasing in many of our sampling sites and the dominant tree pollen is cypress, with high cypress pollen concentrations in Johannesburg. Cape Town Low grass, tree and...

Tree counts are increasing in some cities as spring approaches and a spike for weeds was detected in Gqeberha. Grasses and moulds were low at all sites. High tree counts...

Low pollen concentrations were seen at all the sampling sites, but tree pollen is increasing in Cape Town as cypress begins its pollen release cycle. Cape Town: Pollen concentrations were...

Bitterly cold weather with snow on mountaintops and in cities at high altitude  like Johannesburg, prevailed during this sampling week. In response pollen and fungal spore concentrations remained low. The...

Inclement weather during the midwinter period reduced pollen and fungal spore (mould) concentrations in the atmosphere. Extremely low pollen and mould concentrations were detected at all the sampling sites across...

Summary The rain and storms across South Africa, together with low temperatures have resulted in reduced pollen and mould in the atmosphere. No significant concentrations were recorded. Cape Town The...

Summary Very low temperatures with storms and flooding in many areas occurred in many parts of South Africa in the past week. These adverse weather conditions are reflected in the...

Summary Low temperatures and storms with flooding in some cities reduced pollen and mould in the air. No significant counts were seen. Cape Town Continued storms and heavy rain reduced...

Summary Low pollen counts were seen at every site, but tree pollen is increasing at both the Gauteng sites (Johannesburg and Pretoria) and significant counts were seen for beech (Fagus...

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...
