Local Environmental Conditions
This site in Unincorporated Tiburon is surrounded mainly by woodland, with some open grassland and open water. Oak is the most prominent allergenic tree nearby, with cypress and hazel also present. Beyond the trees, grasses matter a great deal, and mugwort and plantain are the main weed sources. Mugwort is unusually common here compared with most other locations, making it a particularly important local pollen source.
The pollen year starts in late winter, when cypress and hazel flower. Tree pollen peaks in mid-spring, when the weather warms to around 10°C and oak is in full flower. Grass pollen follows, peaking in early summer and easing off by early fall. The most intense period comes through summer, when mugwort and plantain are in flower.

Does pollen in Unincorporated Tiburon 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.

Are pollen levels in Unincorporated Tiburon 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 Unincorporated Tiburon, 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.
