Local Environmental Conditions
This site in Long Beach is surrounded mainly by built-up land, which covers around 58% of the nearby area, with a good deal of open water. Oak is among the allergenic trees nearby. Grasses and weeds such as pigweed and ragweed round out the local mix. In the immediate area, planted trees and mown lawns are the main sources in the built-up parts.
Tree pollen peaks in mid-spring, when the weather warms to around 15°C and oak is in full flower. Then come the grasses, strongest in late spring and fading by early fall. Pigweed and ragweed bring a final peak from early summer into early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels.

How often is the Long Beach pollen forecast updated?

Does pollen in Long Beach 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 Long Beach 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 Long Beach, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
