The latest available daily forecast on every page load. No manual updates or API keys.
Where can I use it?
On websites that allow an iframe in a custom HTML or embed block, including many WordPress, Webflow, Squarespace, and Wix setups. Paste the code into the block and publish your page. Some plans or editors restrict embeds. Email clients and social posts generally don’t support iframes.
Is it really free?
Yes. The free widget includes Pollen.day branding, a link to the full forecast, and data attribution. No account, subscription, or API key is required. Please keep the branding and attribution visible.
How does the pollen score work?
It’s Pollen.day’s 0–100 score, combining tree, grass, and weed pollen forecasts. Higher scores mean more pollen. The color and written level match our website, and tomorrow’s arrow compares the two daily scores. Learn about the data.
Will it fit my website?
The widget fills its container up to 440px wide and is designed for spaces at least 240px wide. The default height is 280px; increase it if your site or browser uses larger text. Its styles are isolated from your page. Auto appearance follows the visitor’s device setting.
What if my embed doesn’t appear?
Check your editor allows iframe HTML. Sites with a Content Security Policy need to allow https://pollen.day in their frame-src directive. If your editor adds a sandbox, allow scripts, same-origin requests, popups, and popups to escape the sandbox for all features. The forecast itself can display without JavaScript. Contact us for help.
What does the widget measure?
We measure widget loads and forecast clicks, the selected city, and the referring website’s domain when the browser shares it. The widget doesn’t set cookies or store visitor identifiers. We don’t collect the host page’s path or query string. Read our privacy policy.
