Casa Nova commands the northeastern Bahia São Francisco River valley as Brazil's largest municipality by area in the semi-arid sertão, where native caatinga scrub, irrigated agriculture, and riparian gallery forest along the São Francisco are the main pollen sources. The very semi-arid climate produces a compressed wet season, while the long dry season concentrates pollen production and the São Francisco River contributes distinctive riparian and irrigated orchard pollen throughout.

How often is the Casa Nova pollen forecast updated?
The Casa Nova pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Casa Nova 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 Casa Nova 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 Casa Nova, 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.
