The Karratha area sits amid spinifex hummock grassland and low acacia scrub typical of the Pilbara, with mangroves and salt-tolerant coastal vegetation fringing the nearby tidal creeks and harbour. Mulga occurs further inland. This is rugged, red-earth country with sparse tree cover overall, and little of the dense forest or grassland pollen load found in temperate Australian cities.

When is pollen season in Karratha?
Karratha, on the Pilbara coast, has a pollen pattern shaped by its hot, dry, semi-arid climate rather than a classic four-season cycle. Native acacias, spinifex and coastal shrubs tend to flower opportunistically following the region's irregular rains, which can fall in the cyclone-influenced wet months (roughly November to April) as well as sporadically at other times. Pollen output is generally low, with short bursts of activity after rain and long quiet stretches during the frequent dry periods.
How often is the Karratha pollen forecast updated?

The Karratha pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Karratha come from nearby or far away?

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Karratha based on measurements or forecasts?

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Karratha, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
