Semaphore's beachside position brings onshore Gulf St Vincent breezes that moderate pollen more than Adelaide's inland suburbs experience, olive and wattle flowering from August, and grass pollen from foreshore parks and reserves peaking September-November. Being right on the coast, Semaphore typically records a milder pollen peak on onshore-wind days than suburbs set further back from the water. The historic jetty precinct's exposed position means pollen rarely lingers for long over the foreshore.

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

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.

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 Adelaide, 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.
