Local Environmental Conditions
The area around this part of Salt Lake City is a mix of built-up land and woodland. Oak heads the list of allergenic trees nearby, ahead of maple. Beyond the trees, grasses matter a great deal, and mugwort and ragweed are the main weed sources. Compared with most places, oak is especially widespread here, which makes it one of the key local allergens.
Oak and maple lead the season in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. The season closes with mugwort and ragweed from midsummer into early fall. The oak period in late spring is usually the most intense time of year here.

How often is the Salt Lake City pollen forecast updated?

Does pollen in Salt Lake City 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 Salt Lake City 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 Salt Lake City, 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. |
