Local Environmental Conditions
Leichhardt, known for its Italian heritage, is defined by tightly packed terrace housing under a strong canopy of exotic street trees, particularly plane trees planted along its main avenues. Small local parks carry mixed exotic and native plantings. With little remaining bushland, Leichhardt's pollen profile leans heavily on deciduous street tree flowering in spring, supplemented by garden shrubs, more so than the harbourside suburbs nearby which retain more native foreshore vegetation.
Leichhardt's dense inner-west streetscape, softened by parks like Leichhardt Oval and generous street tree plantings, sees tree pollen from plane and eucalypt build from August into September, with grass pollen from local ovals and reserves peaking October-December. Being well inland from the harbour breeze, the suburb can hold slightly warmer, stiller air on spring days, letting pollen linger a little longer before dispersing. The suburb's proximity to Rozelle Bay can also draw in humid air on calm afternoons, briefly lifting pollen levels.

When is pollen season in Sydney?
How often is the Sydney pollen forecast updated?
The Sydney pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Sydney 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 Sydney 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 Sydney, 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.

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. |
