Old Sacramento is a central Valley city with valley oak, olive, and abundant ornamental trees. Olive trees bloom in May and are a severe allergen. Valley geography traps pollen in summer heat inversions; air quality and pollen combine to create difficult days.

How often is the Sacramento pollen forecast updated?

Does pollen in Sacramento 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 Sacramento 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 Sacramento, 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.
