Use the Pollen Forecast to Avoid Allergens

[an error occurred while processing this directive]

Pollen forecasts are a very useful way to help combat hay fever and other allergies. This is a prediction of the amount of pollen grains that will be present in the air over the next few days. Forecasts are usually performed by local news and weather stations and include local pollens and allergens.

A forecast is performed by looking at a number of different weather conditions and factoring a knowledge of the plant pollinating characteristics in the local area each season.

Three Influencing Factors

There are three main factors that affect the forecast from day to day and each season:

  • Temperature: Colder temperatures prolong delay production and lead to improved forecasts during the earlier part of each pollen season.
  • Humidity: Lower humidity leads to a higher pollen count. The dryer the conditions, the easier it is for the wind to carry the pollen through the air. Conversely, high humidity or rainy conditions will weigh the pollen down or pull it out of the air, which results in a low pollen count.
  • Wind Speed: Higher winds will shake pollen loose from trees and grasses resulting in increased pollen levels. High winds will also help carry pollen over a longer distance, which can lead to pollens reaching you that may not even be produced in your local area.

Forecasts Are There to Help, Use Them!

Pollen counts and forecasts should be used as a primary means of allergen avoidance both indoors and outside. When allergen levels are high, you need to take extra care to stay indoors and limit your time outside.

Staying inside permanently is clearly not an option. However, you can take several steps to limit your exposure on days when you know the pollen levels are going to be very high. See Tips on Allergen Avoidance
