How it works

Forecast → flag → reschedule

1

Forecast loads with your week view

Open the schedule. The forecast strip is there, always current, fetched from Open-Meteo. No setup.

2

Flagged days stand out

Days above your precipitation threshold glow amber so you notice before the customer calls confused.

3

Reschedule in bulk

Tap the day, pick a new slot, confirm. Grassly moves the jobs, updates customer notifications, and preserves the recurring pattern.

What it does

Scheduling that respects the sky

Forecast on the calendar

Every day of your week view has the high, low, precipitation chance, and an icon. Glance at Monday, see Thursday's issue.

Rain-out flags

Days above your precipitation threshold get a flag so they stand out. Thresholds are per-org — adjust to your climate.

One-click reschedule

Flagged day? Reschedule affected jobs in bulk. Customers get notified automatically with updated times.

Historical fill

Past days show actual observed weather, not forecast. Great for tagging completed jobs with conditions for chemical compliance.

Per-property zone

Forecasts are pulled per service region, not a single station. Customers 40 miles apart get the forecast they actually see.

Works with recurring services

Rescheduling a weekly mow for rain doesn't break the pattern — next week goes back on the original slot.

Weather FAQ

Where does the weather data come from?

Open-Meteo — a reputable public forecast API with global coverage. No API key, no per-request fee, no data sharing.

Can I set my own precipitation threshold?

Yes. Default is 60% chance of rain but you can adjust per organization to whatever flags the days your crews actually can't work.

Does rescheduling automatically notify customers?

Yes, if you have appointment reminders or morning-of reminders enabled. Customers see the new time via SMS or email.

Is this an extra charge?

No — Weather-Aware Scheduling is included on every plan, including Free.
