Cape Town
Grass concentrations increased to exceed 10 grains/cu M on warm, dry days. Tree pollen increased despite rain as significant concentrations were recorded for cypress, plane,pine,oak and olive. Weeds were low. Fungal spores were low in total but a strong spike was seen for Alternaria. This spore exceeded the significant level on dry days of the sampling period.
Johannesburg
Tree pollen is high. Oak pollen has increased and plane, mulberry and Fraxinus were moderate. Grasses and weeds were low as were mould levels.
Bloemfontein
Fungal spore loads remain low. Tree pollen is still high as Celtis (white stinkwood) Olive, Pine, Eucalyptus, Buddleja and Combretum (Bush Willow) continue to flower. Grass pollen is high but lower than the previous week. No weed pollen was detected.
