Local Environmental Conditions
Resort town wedged between the Coral Sea and Daintree hinterland, surrounded by lowland tropical rainforest, mangrove-lined inlets and coconut- and pandanus-planted foreshore. Sugarcane fields occupy cleared flats to the south, adding a seasonal grass-pollen contribution around harvest and regrowth. Ornamental tropical plantings — bougainvillea, frangipani, poinciana — line resort streets. Rainforest and cane country together drive a humid, tree-and-grass-dominated pollen profile through the wet season.
Port Douglas, fringed by rainforest and reef, follows the tropical monsoon pattern with grass pollen from the town's parks and resort lawns building through the dry season from May to October, and tree pollen from eucalypt and paperbark opening later in the dry, around August-October. The surrounding rainforest's density means tree pollen sources are close by, though the wet season's heavy rain, November to April, keeps counts low for much of the year.

When is pollen season in Cairns?
How often is the Cairns pollen forecast updated?
The Cairns pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Cairns 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 Cairns 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 Cairns, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
