Local Environmental Conditions
This part of Ojai sits among a blend of open grassland and woodland. Of the trees nearby, oak is the one that matters most for allergies. Grass pollen adds noticeably to the overall load. Roadside verges and patches of open ground provide further room for grasses and weeds. Wind carries pollen over long distances, so the wider landscape also shapes what arrives here.
Through the year, tree pollen comes first, with oak in flower through spring. From mid-spring, grass pollen rises to a peak around late spring before easing off by midsummer. Weeds on open ground add a smaller late peak from early summer into early fall. Winters average around 10°C and summers around 25°C, with most rain falling in the cooler months.

How often is the Ojai pollen forecast updated?
The Ojai pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Ojai 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 Ojai 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 Ojai, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
