Longview sits in the East Texas Pineywoods, where pine and hardwood forests surround neighborhoods, lawns, and waterways. Its warm, humid climate supports extended grass and weed seasons alongside substantial spring tree pollen. Oak, grasses, ragweed, and winter juniper pollen create overlapping allergy challenges throughout the year. This guide explains seasonal patterns, nearby monitoring data, and practical ways to manage exposure.
Understanding Pollen Counts in Longview
A pollen count measures the concentration of airborne pollen, usually reported as grains per cubic meter of air. Higher concentrations can trigger sneezing, congestion, a runny nose, and itchy or watery eyes in sensitive people, and may worsen asthma. Nearby Tyler measurements provide regional context, but conditions around individual Longview homes and workplaces can differ.
Key Pollen Types and Recent Regional Measurements
Longview’s main pollen concerns change with the seasons, from spring hardwoods to fall ragweed and winter junipers. On April 2, 2026, UT Tyler reported a high tree pollen count of 115 grains per cubic meter, identifying beech, mulberry, oak, pine, and willow. Research checked October 22, 2026, found useful nearby Tyler measurements but no verified, continuous monitoring record within Longview itself.
- Spring Tree Pollen: Oaks generally release pollen from March through May, with the heaviest regional activity usually in March and April; pecan and hickories contribute mainly in April and May.
- Grass Pollen: Bermuda, Johnson, and Bahia grasses contribute during an approximate April–October season, with the strongest activity broadly in May and June.
- Ragweed and Cedar Elm Pollen: Ragweed generally persists from August until a killing frost, often peaking in September and October; cedar elm typically pollinates from August through October.
- Winter Juniper Pollen: Eastern redcedar and transported Ashe juniper pollen contribute during a broad December–March window, often strongest in January and February.
Tyler’s October 21, 2026 report recorded moderate weed pollen at 29 grains per cubic meter, chiefly ragweed, showing that regional exposure continued into late October. These dated snapshots do not establish a long-term Longview trend. Cedar elm is a deciduous elm and is different from the junipers commonly called cedars.
Longview’s Seasonal Pollen Patterns
These approximate regional seasons can shift by several weeks with temperature, rainfall, wind, and frost.
- Spring (March–May): Oak and other hardwood pollen dominate, with conspicuous pine releases, April–May pecan and hickory pollen, and increasing grass activity.
- Summer (June–August): Warm-season grasses remain active depending on rainfall and growth, while pigweed and other weeds contribute; ragweed and cedar elm can begin in August.
- Fall (September–November): Ragweed commonly peaks in September and October and continues until a killing frost; cedar elm contributes mainly through October, while grasses may persist.
- Winter (December–February): Juniper pollen becomes a concern, often strongest in January and February; spring elms may begin releasing pollen in late January or February.
Follow Daily Pollen Conditions in Longview
Use the Pollen Count & Alerts App for daily monitoring and real-time tracking of available tree, grass, weed, and mold spore updates. Check each update’s timestamp and location, since nearby measured counts and Longview forecast indices describe different aspects of exposure. Mold spores are a separate airborne allergen, and a forecast index is not a measurement in grains per cubic meter.
Practical Ways to Manage Seasonal Allergies
Use these everyday steps to reduce exposure and make informed decisions during Longview’s pollen seasons.
