Markham, California is a small locality in Northern California's diverse landscape, where Mediterranean climate conditions create an extended pollen season lasting over eight months each year. The region's valley geography, abundant oak woodlands, and year-round grass growth present significant challenges for allergy sufferers, with peak tree pollen in spring, intense grass pollen in summer, and ragweed dominating fall months. This guide covers the main pollen types affecting Markham residents, seasonal patterns, local monitoring resources, and effective strategies for managing your allergies throughout the year.
Understanding Pollen Count in Markham
Pollen count measures the number of pollen grains per cubic meter of air, indicating allergen exposure levels in your area. When counts are high, allergy sufferers typically experience symptoms including sneezing, runny or stuffy nose, itchy and watery eyes, and potential asthma exacerbation. Monitoring daily pollen levels helps you plan outdoor activities and take preventive measures before symptoms worsen.
Key Pollen Types Affecting Markham Residents
Markham's location in Northern California exposes residents to three distinct allergen categories throughout the year. Research shows that among California patients with respiratory allergies, grass pollen affects 39.2% of sufferers, birch affects 23.7%, and cedar impacts 9.6%, making these among the most significant allergens in the region.
- Oak Tree Pollen: The dominant allergen from March through May, with multiple species including Valley Oak, Blue Oak, and Coast Live Oak producing overlapping pollen seasons
- Bermuda Grass Pollen: The most prevalent grass allergen peaking in June, with year-round production due to California's mild climate and irrigated landscapes
- Ragweed Pollen: Multiple species including Desert, Western, and Giant Ragweed create intense fall allergies, with concentrations peaking in mid-September
- Cedar and Juniper Pollen: Eastern Red Cedar produces significant pollen from January through May, often extending into June in this region
The region's Mediterranean climate with mild winters and hot, dry summers enables extended growing seasons that prolong pollen exposure. Valley geography can trap pollen combined with air pollutants, creating higher concentrations and compounding respiratory issues for sensitive individuals.
Seasonal Pollen Patterns in Markham

- Spring (March to May): Peak tree pollen season dominated by oak, cedar, pine, mulberry, walnut, ash, maple, birch, sycamore, and olive, with March and April being the most intense months
- Summer (June to August): Grass pollen season reaches its peak in June with Bermuda grass, Timothy grass, and ryegrass dominating, while early weed pollen begins appearing in late summer
- Fall (September to November): Ragweed and sagebrush create the highest weed pollen levels, with mid-September marking the ragweed peak and intense allergy symptoms through November
- Winter (December to February): Lowest overall pollen levels with alder and juniper beginning late in the season, though indoor allergens become more significant during these months
