Know how it’ll feel outside and what to wear. Personalised clothing advice, forecasts and beautifully illustrated skies, built around you.
Know what to wear, whatever the weather.
Fairday turns the forecast into clothing advice tailored to how warm or cold you usually feel. Spend less time deciphering weather data and more time getting on with your day.
HOW IT FEELS FOR YOU
See a personalised feels-like temperature that takes wind, humidity and your comfort preferences into account. Fine-tune your recommendations with feedback when an outfit sounds too warm or too cold.
ADVICE FOR YOUR PLANS
Tell Fairday what you’re doing and when, such as going to dinner from 7–10pm. Get clothing advice for the hours you’ll actually be outside.
THE WEATHER AT A GLANCE
Explore hourly and seven-day forecasts, rain and snow charts, rain radar, UV, humidity and air quality. Save cities and check official weather alerts where available.
FOLLOW THE RAIN
Live Activities bring precipitation forecasts to your Lock Screen and Dynamic Island on supported iPhones. Existing activities can receive updates while Fairday is closed; delivery depends on connectivity, system settings and service capacity.
DETAILS YOU CAN FEEL
Drifting clouds, falling rain, changing moon phases and optional haptics bring the weather to life. Enjoy carefully considered interactions in light and dark appearances, with skies that gently change as sunset approaches.
START WITHOUT AN ACCOUNT
Use weather, clothing advice, Plans and Live Activities without signing in. Guest preferences stay on your device. Sign in with Apple or Google if you want to sync your cities and preferences. Weather-alert push notifications require an account and notification permission.
Forecasts and clothing advice are guidance, not guarantees. Official alert coverage varies. For safety decisions, follow your local authorities.
