Overall Risk
Tree Pollen
Grass Pollen
Weed Pollen
Mould Spores


Kimberley has been very hot and dry so the pollen and mould counts have been low but after a little rain the mould counts increased. Grass and weed pollen concentrations in the air were low. Tree pollen was low and included cypress, olive, pine, oak and willow.


Intermittent rain throughout the week removed pollen and mould from the air but on warmer days small spikes were seen for moulds, such as Cladosporium, an allergenic mould and basidiospores (includes mushroom spores). Very low tree, grass and weed pollen levels were seen.

Cape Town

The grass levels ranged from low to high according to weather patterns. Grass counts were high on warm, sunny days. Tree counts diminishing, but pine, oak, cypress, mulberry and olive were detected. Weed levels were consistently low. Mould counts were generally low but one significant spike was seen for Alternaria, an allergenic mould.


Grass counts were low to moderate. Tree counts are declining but acacia, buddleja, olive, pine and white stinkwood are still present in the air. Weed counts were low and mould counts were similarly low.


Grass counts were low to moderate. This city has the greatest variety of tree pollen. The counts are low as the spring tree flowering season comes to an end and include: Oak, pine, plane, bush willow, rhus, mulberry and eucalyptus. Weed and mould counts are low.


Grass counts are low. Tree pollen levels are low and include: Olive, pine, plane, birch and oak. No weed pollen was detected and mould counts are low.


The mould count soared following a wet spell and very high counts were seen. Ascospores increase after rain and these were seen in large quantities together with Cladosporium, an allergenic mould. Low grass and weed counts were detected. Tree counts were also low and included: Birch, eucalyptus, willow and cypress.
