South Gate's pollen season opens with acacia and introduced olive from January in the mild Southern California coastal climate. Oak and grass follow through March and April, with the season peaking earlier than most US cities. Onshore Pacific winds periodically disperse urban pollen, while the Los Angeles River corridor and surrounding Los Angeles County urban areas contribute additional tree and grass pollen across the densely built coastal plain.

The South Gate 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 South Gate, 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.
