Why?

Pollen counts have increased by 96.3% worldwide since 1998. A dramatic increase in pollen in the air has been recorded in 17 locations in the northern hemisphere. 30% of the world's population suffer from allergic rhinitis (aka hay fever). Unfortunately, the pollen count is highly seasonal, species- and weather-dependent and depends on many local factors. Numerous websites and apps from weather portals or pharmaceutical companies try to take this dynamic into account with current pollen count data and forecasts.

In my daily routine, however, I don't want to have to use yet another app or regularly check websites for local pollen counts. There are days of the week when I'm out and about a lot and am therefore exposed to pollen. On other days, I sit in an air-conditioned office with filtered air. My calendar with all my private and professional appointments is the linchpin here. Here I can see when I am where and how much I will be exposed to pollen. But this is where an important piece of information is missing: how strong will the pollen count be on this day and at this location?

By integrating the pollen forecast directly into the calendar, I am much more likely to pay regular attention to the pollen information. This increased visibility helps me to better plan my activities and take the necessary precautions to effectively counteract allergies or respiratory illnesses.

Frequently asked questions

What is a Webcal pollen forecast?

A Webcal is a calendar subscription format that allows you to view live data, like a pollen forecast, directly in your calendar app without downloading manual files. Unlike a static import, a Webcal pollen feed stays connected to the server, so your calendar automatically updates with the latest pollen levels for the next 5 days.

How do I subscribe to the pollen forecast ICS feed?

To add the forecast to your calendar, click the "Add to your Calendar" button after selecting your location and pollen index.

  • For iPhone/iPad: Tap the link and select "Subscribe" when prompted.
  • For Google Calendar: Copy the generated webcal URL, go to "Settings" > "Add calendar" > "From URL," and paste the link.
  • For Outlook: Use the "Add Calendar" > "Subscribe from web" option.

Once added, the pollen forecast ics will appear as a new calendar layer that you can toggle on or off.

How often does the pollen calendar update?

The feed updates automatically every day to provide the most accurate forecast (you can also manually configure different update frequencies). Pollen counts can change rapidly due to weather conditions like wind and rain, so our system refreshes your calendar events daily to ensure you have the latest health recommendations and risk levels for your specific location.

How can I change my location or pollen type?

Because Webcal feeds are generated for specific parameters, you cannot edit the location inside your calendar app. To change your monitored area or switch from "Grass" to "Birch," simply return to Pollencal.com, search for the new location or pollen type, and subscribe to the new feed. You can then delete the old subscription from your calendar settings.

Which calendar apps support this pollen feed?

The Pollencal feed uses the standard .ics and Webcal format, making it compatible with virtually all modern calendar applications, including Google Calendar, Apple Calendar (iCal), Microsoft Outlook, and standard business calendars.

Why do I see emojis in my calendar events?

We use emojis to give you a quick visual indicator of the Universal Pollen Index (UPI) without needing to open the event details. This allows you to check the pollen risk level at a glance while viewing your daily schedule.
