Local Environmental Conditions
The area around this part of Happy Camp is heavily wooded. Along a watercourse nearby, trees, shrubs and reeds grow in the damper ground and add their own pollen. Around here, tree cover makes trees an important source. Gaps in the canopy, trails and forest edges give grasses and herbs room to grow.
Through the year, trees are the first to release pollen, with a peak around mid-spring. From mid-spring, grass pollen rises to a peak around early summer before easing off by late summer. A smaller weed peak follows from early summer into early fall, from plants on verges and waste ground. Locally, winters average around 10°C and summers around 15°C, with most rain falling in the cooler months.

How often is the Happy Camp pollen forecast updated?

Does pollen in Happy Camp 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 Happy Camp 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 Happy Camp, 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. |
