Most powerful ways to connect Open Weather and Cal.com
Open Weather + Cal.com + Google Calendar: When a new booking event is created in Cal.com, the automation retrieves weather forecasts for the meeting location. If specific weather conditions are met (e.g., rain), a Google Calendar event is created, potentially suggesting rescheduling.
Cal.com + Open Weather + Twilio: When a booking event is created in Cal.com, the automation retrieves the current weather for the event location. It then sends a Twilio message to the client reminding them of the appointment, and informing them of the local weather conditions.
