Pollen Count & Forecast for Darwin

Darwin’s dry season (May–October) is dominated by Grass (Poaceae) pollen; African Mahogany (Khaya senegalensis) frequent along Cavenagh Street and city parks. Wattles (Acacia) contribute significantly from Charles Darwin National Park. The late wet season (March–May) sees high Spear Grass (Sorghum intrans) pollen levels, originating from Casuarina Coastal Reserve and along Elizabeth River.

Tropical humidity and monsoonal winds trap moisture against the flat coastline, leading to localised damp conditions. The wet season (November–April) sees high Mould (Alternaria, Aspergillus) spore counts, from damp leaf litter in George Brown Darwin Botanic Gardens and tidal mangroves near East Arm.
