🌿 2026 Allergy Season: Read the 2026 Spring Allergy Forecast — what to expect this season and how to prepare.
Local Allergy Overview
New Castle, Delaware, experiences a humid subtropical climate with four distinct seasons. The region’s proximity to the Delaware River and Atlantic coast contributes to moderate humidity levels year-round, which can cause allergens like mold spores to thrive. The combination of urban and suburban green spaces leads to the presence of various pollen-producing plants, making sinus allergies a common issue for many residents.
Top Allergens in New Castle
- Oak Pollen: One of the earliest spring allergens, oak trees release pollen in April and May, triggering sinus irritation in sensitive individuals.
- Grass Pollen: Common in late spring and early summer, grasses like Bermuda and Timothy produce pollen that affects many allergy sufferers.
- Ragweed: A dominant fall allergen, ragweed pollen peaks in late August through October, often causing severe sinus congestion.
- Mold Spores: Thanks to the region’s humidity, mold spores are present throughout the year, especially in damp areas and during rainy seasons, aggravating sinus symptoms.
Allergy Seasonal Calendar
Spring (March - May): Tree pollen season begins with oak, maple, and birch trees releasing large amounts of pollen, often causing sneezing and sinus pressure.
Summer (June - August): Grass pollen is most active during this period, with Bermuda and Timothy grasses contributing to ongoing sinus irritation.
Fall (September - November): Ragweed pollen dominates the landscape, causing peak allergy symptoms like congestion and sinus headaches.
Winter (December - February): Outdoor pollen counts are low, but indoor allergens like dust mites and mold spores can still affect sinus health, especially in heated indoor environments.
