Sugar Land pollen forecast - today, tomorrow and the week ahead

On 16 July 2026, overall pollen levels in Sugar Land are low. Cypress is the main contributor to airborne pollen, while grass and ambrosia remain at lower levels

On 17 July 2026, pollen conditions in Sugar Land will be similar to today, with cypress at low levels, grass at low levels, ambrosia at low levels

According to the five-day outlook, cypress, grass, and ambrosia pollen levels are expected to gradually decrease, suggesting improving conditions later in the week.

On 16 July 2026, Cypress is the dominant pollen source in Sugar Land. grass and ambrosia are also present but at lower levels. birch, oak, willow, alder, and artemisia are not currently active.

Sugar Land's pollen season opens with cedar and oak from late January in the mild Gulf Coast climate. Grass pollen follows through March and April, with ragweed extending the season into October. The flat Gulf Coast prairie landscape allows pollen to disperse readily, while the Brazos River corridor and surrounding Houston metropolitan woodland and farmland contribute substantial tree and grass pollen under prevailing southerly winds.

The Sugar Land 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 Sugar Land, 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.
