For millions of people across the United States, seasonal allergies are more than just a nuisance — they’re a disruptive and often debilitating part of daily life. If you’ve found yourself sneezing, rubbing itchy eyes, or feeling congested more than usual, it’s worth checking the pollen count today in your area. But what does the pollen count actually mean, and how can it help you manage your symptoms?
This blog explores how the daily pollen forecast ties into your allergy symptoms, how different types of pollen — including grass and ragweed — affect the body, and what steps you can take to reduce the impact of a severe pollen allergy.

What is the pollen count, and why does it matter?
The pollen count refers to the concentration of pollen grains in the air over a 24-hour period. It's typically measured in grains per cubic meter of air. Local weather services and allergy networks track this data and break it down by pollen type — including tree pollen, grass pollen, and weed pollen — to help allergy sufferers prepare for high-exposure days.
Pollen counts are often highest in the morning and can vary depending on weather conditions. Warm, dry, and windy days tend to spike counts, while rain can temporarily suppress airborne pollen by washing it to the ground.
A high pollen count is more than just a number. For those with seasonal allergies, a high pollen count is a real-world indicator of how intense your symptoms might be today.
Common symptoms of pollen allergies
Exposure to pollen can trigger a wide range of symptoms across the respiratory system, eyes, skin, and even lungs. Some of the most common allergy symptoms from pollen include:
- Sneezing
- Runny or stuffy nose
- Itchy, red, or watery eyes (pollen eye allergy)
- Postnasal drip
- Coughing or throat irritation
- Fatigue and headaches
- Skin reactions like hives or itchiness
In more severe pollen allergy cases, individuals may experience intensified asthma symptoms or sinus infections due to chronic inflammation.
Certain individuals may also notice pollen allergy symptoms on skin, especially during periods of high exposure or if they have sensitive skin. These reactions can include redness, dryness, or an itchy rash — especially after outdoor activity.
Grass pollen and ragweed: major seasonal triggers
Not all pollen is created equal. Grass pollen allergy is especially common in late spring and early summer. Common culprits include Kentucky bluegrass, Timothy grass, and orchard grass. These grasses release microscopic pollen grains that easily travel through the air.
Later in the year, ragweed season takes over — typically starting in late summer and extending into the fall. Ragweed is infamous for its ability to produce a staggering amount of pollen. A single plant can release up to a billion grains in one season, according to the Asthma and Allergy Foundation of America (AAFA). Even if you don't live near a field of ragweed, the pollen can travel hundreds of miles by wind.
For many allergy sufferers, the transition from grass to ragweed season marks a second wave of symptoms that can feel unrelenting, especially if current high allergens include both types.
Monitoring today's pollen and mold count
In addition to pollen, mold spores are another major airborne allergen. That’s why many forecasts include a combined pollen and mold count for today — an essential resource for allergy sufferers since both allergens tend to thrive in similar weather conditions.
Tracking the local count — often searchable by ZIP code — is one of the best ways to plan your activities and reduce exposure. On high-count days, consider:
- Rescheduling outdoor activities
- Keeping windows and doors closed
- Using an air purifier for pollen allergies indoors
Even small changes in routine can make a big difference on high-allergen days.
Managing severe pollen allergy: what actually helps?
If you’re dealing with severe pollen allergy symptoms, small lifestyle adjustments may not be enough. In these cases, allergists often recommend a combination of:
- Antihistamines or nasal corticosteroids to reduce inflammation and ease symptoms
- Allergy testing to identify specific triggers
- Immunotherapy (allergy shots or tablets) to gradually reduce sensitivity
- HEPA-based air purifiers for pollen allergies to minimize indoor exposure
According to the American College of Allergy, Asthma & Immunology (ACAAI), improving indoor air quality is one of the most effective ways to manage year-round and seasonal allergies. Reducing humidity and investing in proper filtration systems can drastically decrease pollen levels inside your home.
Final thoughts
If your allergies feel particularly bad today, you're not alone — and you're not powerless. Understanding what today's pollen count is/means and how it connects to specific types of allergens like grass pollen and ragweed is a first step toward regaining control from environmental allergens.
Whether you're dealing with mild irritation or severe pollen allergy, staying informed empowers you to make smarter choices about when to go outside, how to protect your indoor air, and when to seek professional support.
For a personalized diagnosis and long-term treatment plan, always consult a board-certified allergist. With the right tools and knowledge, even your toughest allergy days can become more manageable.
