Midtown Reno sees the same pollen timeline as the rest of Reno, beginning with palo verde and mesquite in January then mulberry follows, running through February. Grass follows, peaking through March and April, while monsoon moisture from July through September brings a brief second wave of grass and weed pollen. The hot desert climate concentrates the main spring season, with little rainfall to interrupt pollen release, a defining feature of the local season.

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

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.

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 Reno, 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.
