iPhone Calendar Apps with Built-In Weather Compared
Most iPhone calendar apps either omit weather completely (Apple Calendar and Google Calendar on iOS) or show only a tiny daily sun icon locked behind a $40–$57/year subscription. Cloud Calendars embeds a full Apple WeatherKit station directly into its $0 Free plan—placing hourly temperatures and icons beside every timeline hour in Day view, daily highs and lows atop Week columns, a 10-day searchable city Weather Hub (feels-like, precipitation, wind & gusts, UV index, humidity, and pressure), and one-tap event drafting straight from any forecast hour. Arte Soft develops Cloud Calendars and publishes this comparison.

Why Apple Calendar and Google Calendar Still Lack Weather on iPhone
People often remember seeing tiny weather icons inside Google Calendar many years ago (a retired desktop "Labs" widget) or inside desktop Outlook on Windows, then wonder where the toggle went on iPhone. Neither Apple Calendar on iOS 18 nor the official Google Calendar iPhone app includes hourly or 10-day weather forecasts inside the calendar grid—forcing outdoor workers, runners, parents, and event planners to flip constantly between two apps.
Bringing Apple WeatherKit directly into the Day and Week grid turns weather from an afterthought into an active scheduling constraint: you spot the 16:00 rain band and 28 km/h gusts before sending the tennis or site-walk invite, not an hour before kickoff.
Account Sync, Widgets & Platform Support Across Weather Calendars
| Dimension | Cloud Calendars | Fantastical | Timepage | BusyCal iOS |
|---|---|---|---|---|
| Google, iCloud & Microsoft 365 sync | iCloud + Google (Free); Microsoft + Teams (Premium $49.99/yr) | All 3 (full multi-set sync in Premium ~$57/yr) | Reads iOS Calendar Accounts ($14.99/yr) | iCloud, Google, Exchange & CalDAV ($14.99 one-time) |
| Date + Weather Home Screen widgets | Small & Medium Calendar & Weather widgets ($0 Free) | Date/Agenda + Weather widgets (Premium) | Minimalist weather & agenda widgets | Agenda & Month widgets with optional weather icons |
| Per-event address weather vs selected place | Forecasts reflect your current or selected city in Weather Hub | Premium resolves weather for individual event location addresses | Selected / current location forecast | Configured primary weather location |
| Wind gusts & UV index visibility | Explicit wind/gusts & UV index cards inside Weather Hub | Summary conditions & precipitation chance | Wind speed, humidity & rain probability | Temperature, condition icon & rain chance |
| Supported Platforms | iPhone & iPad (iOS / iPadOS 18.0+) | iPhone, iPad, Mac, Watch, Vision Pro & Windows | iPhone, iPad & Apple Watch | iPhone, iPad & Watch (Mac sold separately) |
| ICS calendar feed vs real live WeatherKit API | Live Apple WeatherKit API (updates dynamically) | Live AccuWeather API | Live Apple WeatherKit API | Live weather API |
Why Live WeatherKit Beats Free "Weather ICS URL" Subscriptions
A common workaround for Apple Calendar and Google Calendar is subscribing to a free third-party `webcal://` weather `.ics` URL. Those feeds clutter every single day with fake all-day events like `"☀️ 72°/54°"`, lag 12 to 24 hours behind fast-moving storms because of ICS polling delays, offer zero hourly wind or rain timing, and pollute search results and widgets.
Native API integration like Cloud Calendars’ Apple WeatherKit connection keeps meteorological data cleanly separated from actual calendar events while updating dynamically.

Understanding the 10-Day Forecast Horizon and Selected Place
Atmospheric physics limits actionable daily weather models to roughly 7 to 10 days; beyond day 10, skill drops toward historical seasonal averages. Cloud Calendars displays up to ten returned days from Apple WeatherKit so every number shown in your Week and Weather Hub views reflects real model guidance rather than speculative 45-day filler.
Always verify the city name shown in the Weather Hub when scheduling an event in another town—your grid displays weather for your current or selected place.
Turning a Clear Sky Window Into an Event Draft in One Tap
Inside Cloud Calendars’ Weather Hub, spotting a calm, sunny two-hour window between morning showers and evening wind gusts doesn’t require memorizing the clock and switching tabs.
Tap an available forecast hour directly to start an event draft pre-aligned to that hour, then verify the date, duration, and target calendar before saving.
What it looks like
What to do
- Grant Location permission (or search your city manually in the Weather Hub) so Cloud Calendars fetches accurate Apple WeatherKit forecasts.
- Open Day view to see hourly temperatures and weather icons right beside your appointments, or Week view for daily highs and lows.
- Open the Weather Hub before outdoor workouts, shoots, or kids’ games to check wind gusts, UV index, and precipitation timing—not just the daily icon.
- Tap an available dry forecast hour in the Weather Hub to start an event draft immediately, then confirm the target calendar.
- Remove old read-only weather `.ics` subscriptions from iOS Settings once you switch to native WeatherKit views.
Questions
- Where does Cloud Calendars get its weather forecast data?
- The iPhone and iPad app uses Apple WeatherKit for your current or selected place, displaying hourly conditions and up to ten returned daily forecast days. (Note: the interactive demo on cloud-calendars.com uses Open-Meteo.)
- Do I have to pay a subscription to see weather inside Cloud Calendars?
- No. Both in-grid hourly/daily forecasts and the full Weather Hub—plus small and medium Calendar & Weather Home Screen widgets—are included in the $0 Free plan.
- Why don’t dates three weeks from next Tuesday show weather icons yet?
- Apple WeatherKit returns up to ten days of daily forecast data. Dates beyond the available forecast window acquire weather icons automatically as they move within the 10-day horizon.
