Local Environmental Conditions
This site in Rancho Palos Verdes is surrounded mainly by open water, which covers almost 65% of the nearby area, with some open grassland. Lawns and planted trees in a nearby park add to local grass and tree pollen. Grasses, mugwort and pigweed growing in the surroundings are the main non-tree sources of pollen.
Grasses take over in late spring, with temperatures around 15°C, and their pollen lingers into early fall. Later, mugwort and pigweed keep weed pollen in the air through summer. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. Day to day, sunshine and wind lift the counts, while a spell of rain can bring them down sharply.

Are pollen levels in Rancho Palos Verdes 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 Rancho Palos Verdes, 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.
