Sinus pressure and the weather
Sinuses react to pollen, pressure swings and poor air. Feelcaster watches all three where you are and alerts you before a rough stretch.

Strongest first. You choose which triggers apply to you in the app.
Pollen
Tree, grass and weed pollen, carried further on windy days. Starts to count at: Moderate pollen and above.
Pressure swings
Air pressure rising or falling fast, usually around a passing front or storm. Starts to count at: A swing of about 6 hPa within 3 hours, or a clear shift from the day before.
Air quality
Smoke, smog and fine particles. Starts to count at: A US Air Quality Index above 50, strongest past 100.
Heat
Hot afternoons, high feels-like temperatures and warm nights. Starts to count at: A feels-like temperature from 80°F, strongest near 103°F.
Thunderstorms
Thunderstorms, and air that is primed for them. High pollen makes them count for more. Starts to count at: Thunderstorms in the forecast.
One thing to do on those days
Rinse off after time outdoors in pollen season, keep windows shut on windy days and keep water nearby.
Sinus pressure: questions people ask
Why do my sinuses ache before a storm?
Pressure falls ahead of many storms, and many people feel it in their sinuses and ears. Feelcaster watches how fast the pressure is changing and tells you before a swing.
Which pollen does Feelcaster track?
Tree, grass and weed pollen, from Open-Meteo and Google’s pollen data. Windy days carry it further, so Feelcaster counts wind in.
