Local Environmental Conditions
The area around this part of South Dos Palos is largely open grassland. Mercey Hot Springs keeps the ground around it moist, supporting dense vegetation that adds to local pollen. Grass pollen is significant here, and pigweed contributes weed pollen. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Through the seasons, grass pollen dominates, building from mid-spring to a peak around late spring and lasting until midsummer. Pigweed keeps pollen in the air from early summer into early fall. Temperatures range from around 10°C in the coldest month to around 15°C in the warmest, with most rain falling in the cooler months.

Does pollen in South Dos Palos 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 South Dos Palos 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 South Dos Palos, 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.
