Local Environmental Conditions
This location in Midpines is heavily wooded, with some open grassland. The allergenic tree mix nearby includes oak. Grasses along roadsides, verges and open ground also add to the overall pollen load. Gaps in the canopy, trails and forest edges give grasses and herbs room to grow. Much of the pollen in dense woodland is released high in the canopy, where the wind carries it easily.
Tree pollen peaks in late spring, when the weather warms to around 15°C and oak is in full flower. Grass pollen follows, peaking in early summer and easing off by early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. By late fall, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Midpines pollen forecast updated?

Does pollen in Midpines 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 Midpines 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 Midpines, 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. |
