How to connect?

Lehi's parks and the Jordan River corridor feature oak, ash, and cottonwood as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. The Wasatch Mountain foothills to the east contribute pine and grass pollen, while the enclosed Utah Valley setting concentrates pollen under prevailing winds and spring temperature inversions across the rapidly growing city.

When is pollen season in Lehi?
Lehi's pollen season opens with elm and cottonwood from late February, followed by oak and ash through April and May. Grass pollen peaks through June and July. The enclosed Utah Valley setting between the Wasatch Mountains and Utah Lake concentrates pollen under calm conditions, particularly during spring temperature inversions. The high altitude and semi-arid climate mean the season is shorter but can be intense, particularly during warm, dry spring days.
How often is the Lehi pollen forecast updated?

The Lehi pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Lehi 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 Lehi 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 Lehi, 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.
