Local Environmental Conditions
Most of the area around the center of Merrylands West is built-up land, with some woodland. Olive is the most prominent allergenic tree nearby, with plane tree also present. Grasses are a major source, with pigweed and plantain adding to the weed pollen load. Compared with most places, olive is especially widespread here, which makes it one of the key local allergens.
Tree pollen peaks in early spring, when the weather warms to around 15°C and olive and plane tree are in full flower. Grass pollen follows, peaking in mid-spring and easing off by mid-fall. The season closes with pigweed and plantain from early summer into early fall. The olive period in early spring is usually the most intense time of year here.

Are pollen levels in Merrylands West 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 Merrylands West, 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.

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. |
