Redding, located in the northern Sacramento Valley of California, experiences one of the highest pollen counts in Northern California. The city's geographic position traps and concentrates pollen from oak trees, agricultural crops like walnuts and olives, and extensive grasslands. This article provides essential information about Redding's pollen types, seasonal patterns, recent trends, and effective management strategies to help residents navigate the extended allergy season.
Understanding Pollen Count in Redding
Pollen count measures the concentration of pollen grains per cubic meter of air, indicating how much allergen is present in the atmosphere. When pollen levels are high, typically above 50 grains per cubic meter for trees or 20 for grasses, allergy sufferers commonly experience itchy and watery eyes, sneezing, coughing, nasal congestion, runny nose, and respiratory distress for those with asthma.
Key Pollen Types and Recent Trends in Redding
Redding's position in the Sacramento Valley, combined with commercial agriculture and abundant native vegetation, creates exceptionally high pollen concentrations throughout most of the year. Recent measurements show oak pollen at 11 ppm and pollen levels frequently reaching the 4.9-7.2 range during windy spring conditions, ranking the northern Sacramento Valley among the most allergenic areas in the United States.
- Tree Pollen (Oak, Walnut, Olive): Peaks March-April with oak causing significant hay fever and asthma; commercial walnut and olive cultivation adds extremely allergenic crops
- Grass Pollen (Bluegrass, Bermuda, Timothy): Produces the bulk of airborne pollen in Sacramento Valley; peaks April, May, and September with exceptional quantities released during June-July hay cutting
- Weed Pollen (Ragweed, Wormwood, Amaranth): Peaks August-September with recent ragweed readings at 4 ppm; extends through fall months
Climate change has significantly worsened conditions in Redding, with pollen seasons lengthening by 20 days from 1990-2018 and pollen production increasing by 21 percent. Projections indicate pollen seasons could start 10-40 days earlier by the end of the century, with pollen production potentially doubling by 2100 as temperatures increase. Warmer winters and extended freeze-free seasons are allowing trees, weeds, and grasses more time to prosper and release pollen.
Seasonal Pollen Patterns in Redding
Redding experiences distinct pollen patterns across seasons, with an overall active allergy season extending from late January through early November.
- Winter (December to February): Late January marks the beginning of tree pollen season with walnut, maple, willow, and mulberry starting to release allergens
- Spring (March to May): Dominated by tree pollen peaks in March-April from oak, walnut, and olive; grass pollen production begins late February with peaks in April and May
- Summer (June to August): Grass pollen remains active through October with exceptional quantities released during June-July hay field cutting; weed pollen begins rising in August
- Fall (September to November): Peak weed pollen season in August-September from ragweed, wormwood, and amaranth; grass pollen peaks again in September before the season ends in early November
