The Best Weather App for Runners (Who Hate Getting Soaked)

Every runner has done the ritual: check the hourly forecast, check the calendar, do mental interval math, pick a slot… and still hit the 4 PM shower that "wasn't supposed to happen."

What runners actually need

• Hourly rain, not daily summaries. "60% chance today" is useless for picking a 45-minute slot.
• Your schedule in the picture. The driest hour doesn't help if you're in a meeting.
• A duration-aware answer. A 45-minute run needs a 45-minute window — not a dry moment.

The honest shortlist

Apple Weather — free, fine, blind to your day

Solid hourly rain since it absorbed Dark Sky. You still do the calendar math yourself.

CARROT / Weathergraph — great data, still no schedule

Both are excellent hourly-forecast apps with strong complications. Neither knows about your 2 PM stand-up.

Calendar Weather — built exactly for this

Ours. Create a "Run" activity with your duration, allowed hours, and days. The engine finds the driest window that fits inside your free time and shows it as a green band on the timeline — with your meetings drawn right there, and the same answer on your Apple Watch face.

How Calendar Weather solves this

Set up "Run · 45 min · 6–9 AM and 5–8 PM · Mon/Wed/Fri" once. Every day, the dashboard answers the only question: when do I run? If the whole evening is wet, it says so plainly — and points to the lightest stretch instead.
