When suffering from hay fever, it can often be difficult to pinpoint exactly when symptoms start. However, by doing a bit of research into hay fever, you’ll be able to establish exactly when you might start to react. This, in turn, will help to prevent symptoms from occurring altogether with help from medication like Nasonex. Without further ado, let’s take a look into when certain types of pollen occur. Tree pollen typically occurs from late March to mid-May. Grass lasts from mid-May until July, and weed pollen covers the end of June to September.

It All Starts in the Spring

Spring is the most common time for allergy symptoms to arise, with pollen from trees causing them. Spring allergy season lasts until late May and affects around 25% of people. The grass pollen season lasts from May to July, and most people are allergic.

Because of the varying weather conditions throughout the United Kingdom, the hay fever season will begin at various times. There are significant weather differences between the north and south of the UK, with more rain in the north. The start of the grass pollen season is usually in the first two weeks of June, as seen with grass pollen. There are two peaks, with the second, lower peak occurring in the first two weeks of July and ending gradually thereafter.

Several variables impact the start date of the pollen season. In the winter, low temperatures will keep plants and trees dormant for longer into the new year. Less pollen is produced at lower temperatures, however, this may vary depending on soil and air temperatures in the spring.

The amount of pollen is also influenced by seasonal changes, such as the dry season. Pollen is also influenced by the weather since it depends on how hardy various species are and how well they deal with a variety of different sports in one location.

What will the impact of climate change be on pollen distribution in the United Kingdom?

Pollen may be influenced by a changing climate in three ways:

1. The pollen season in the United Kingdom is expected to get longer as a result of climate change. This will cause pollen levels to rise, especially if temperatures increase and rainfall decreases.
2. It’s conceivable that climate change will cause pollen to become more potent – each pollen particle might have varying quantities of the allergy-inducing substance on it.
3. Changes in the geographic distribution of allergenic plants, as a result of climate change, also pose a risk to the UK. Invasive species such as ambrosia (common ragweed) are on the watch list for introduction into new regions. A ragweed plant can produce a billion grains of pollen each year, and its pollen is responsible for severe allergic responses.
