How to Add Weather to Your iPhone Calendar

Your calendar knows when you're busy. The weather app knows when it rains. Getting them onto one screen is weirdly hard — here are the options, ranked.

Option 1: Subscribe to a weather calendar feed

Some services publish iCal feeds that insert the day's forecast as an all-day event.

• Pros: works inside the stock Calendar app.
• Cons: one text line per day, no hourly rain, clutters every calendar view, and the feed provider sees your subscription.

Option 2: Split-screen the two apps

On an iPad you can put Weather and Calendar side by side. On an iPhone you flip between them and hold the merge in your head — which is exactly the guessing game that gets you soaked.

Option 3: An app that overlays both

This is the approach we built Calendar Weather around: your events drawn directly on the hourly precipitation curve.

How it works

1. Grant read-only calendar access (events never leave your device).
2. Pick your forecast spot.
3. The dashboard shows the next 24 hours: rain as a wave, your meetings as capsules on top, and a green band on the best dry window for your activities.

How Calendar Weather solves this

No feeds, no split screens, nothing written into your calendar. One timeline answers the merged question — "can I fit a ride between the 2 PM stand-up and the rain?" — at a glance, on iPhone and Apple Watch.
