06:00 · SATURDAY 13 JUNE · YOUR DROPZONE
Know before you go.
One push notification every morning telling you whether it's a jump day at your dropzone. No app to download, no checking five weather sites from bed.
In development. Free for early testers at our first dropzone.
“Likely a jump day — light winds, clear skies.”
Thresholds set by your dropzone’s instructors · lands on your lock screen
Three colours. One clear reason.
The exact message that lands at six, worded by people who jump.
“Likely a jump day — light winds, clear skies.”
Conditions look good across the board. Worth the drive.
Light sock, clear sky, sun out.
“Marginal — gusts near limits around midday.”
Marginal on one factor. Jumpable for some, a wait-and-see for others.
Sock pinned flat. Watch it.
“Unlikely today — cloud base too low.”
A scrubbed day. Sleep in, sort your kit, watch tunnel videos.
Plane tied down. Not today.
Checked while you're still asleep
Every morning JumpDay pulls the day's professional forecast for your dropzone's exact coordinates and runs it against the conditions that actually scrub jumps.
Forecast pull
Wind, gusts, upper winds, cloud base, rain and visibility for the whole jumping day, from Meteomatics, a professional weather service used across aviation and energy.
Jumpable or not
The forecast is scored against wind, gust, cloud and visibility limits, numbers each dropzone confirms with its own instructors.
Verdict on your lock screen
Green, amber or red, with the one reason that matters. It lands like a text message, before you've left the house.
The six things that scrub a jump day
What we check, every morningSurface wind
Checked against your dropzone's limits, including the lower student limit.
Gusts
A sudden gust on final is what hurts people. Gust spread gets its own rule.
Upper winds
Strong upper winds move the spot and stretch the canopy ride home.
Cloud base
You have to see the ground from exit. Low cloud closes the door.
Rain
Rain stops play. Even a passing shower parks the plane for a while.
Visibility
Haze and mist below minima mean no lift, however blue it looks above.
Blue skies are better when you knew they were coming
JumpDay rides on a wallet pass. Add it to Apple Wallet or Google Wallet once, and the morning verdict turns up on your lock screen on its own. Nothing to install, nothing to open, nothing to remember.
Your dropzone. Your limits. Your weather desk.
Register your dropzone, set the thresholds your instructors actually use, and JumpDay runs the weather comms your staff currently do by hand. Pause it, tune it, see what was sent.
-
The 6am jumper verdict Every local jumper gets your go/no-go before they leave the house. The morning phone calls stop.
-
The 4pm tandem update Tomorrow's customers hear “travel as planned” or “rebook free” automatically. That's your manual text round, retired.
-
The recall button Wind drops at eleven? One press: “It's cleared, slots on the next load.” One filled load pays for the month.
-
The free website widget, and a weekly report Your “are we jumping?” page updates itself. Every Monday: sends, reach, verdict accuracy, calls saved.

The honest answers
Does a green verdict mean I'm definitely jumping?
No. Weather changes, planes break, and the final call always belongs to your dropzone and instructors. JumpDay saves you wasted drives and dawn forecast-scrolling, it doesn't replace anyone's judgement.
I'm booked for a tandem jump. Is this for me?
Yes. If your dropzone runs JumpDay, you'll get an update at 4pm the day before your jump telling you whether to travel as planned or rebook free. It comes with your booking, nothing to set up.
Why is there no app?
Because you don't need one. The pass sits in the wallet you already have, and the notification arrives on its own. One less app icon, one less login.
Which dropzones does it cover?
We're starting at a single dropzone, with thresholds confirmed alongside its instructors before launch. Any dropzone can register interest now and be next in line.
Where does the weather data come from?
Meteomatics, a professional weather API used across aviation and energy. We pull the full day's forecast for the dropzone's exact coordinates, not the nearest town's.
Want the morning verdict?
JumpDay is in development, with testing at a first dropzone coming next. Leave your email and you'll be first on the list when your dropzone goes live.
Only emails about JumpDay at your dropzone, nothing else. Prefer to talk? charlie@extremeinternational.com
