How to use Can You Send
Can You Send answers one question before you drive to the crag: has the sandstone likely dried enough to climb after rain? Wet sandstone loses strength and holds break, so pulling on it too soon trashes routes for everyone. Here's the beta.
1. Pick your crag
Open the home page and tap an area on the map or in the list. Every area has its own page and link, so you can send it to your partner.
2. Read the call
- 🟢 Likely dry: no measurable rain for long enough, and none coming soon. Go get it.
- 🟡 Use caution: rain fell a while ago, only a trace fell recently, or rain may be on the way. The page says when ("It might rain today: 40% chance around 3 PM") and when the rock should be climbable again. Climb it like a runout: eyes open.
- 🔴 Rock is likely wet: a gauge near the crag measured real rain (0.10 inch or more) and, at the forecast humidity, wind and sun, it hasn't had time to dry. Rest day, gym day, or limestone day. Give the sandstone time.
Every hour the site checks real rain gauges near each crag and the National Weather Service forecast. How long the rock takes to dry depends on how much rain fell and the weather after: a sprinkle in dry desert sun is gone in hours, while a soaking in cool, humid, cloudy weather can take a week.
3. Dig into the details
- Rain, last and next 7 days: a chart of measured and forecast rain.
- Rain chance, wind and temperature by the hour, with a link to the full NWS forecast. Friction temps included.
- Sun and shade: which walls are baking and which are hiding.
- Rain gauges on a map, with their recent totals and the nearest webcam.
- Local guidance: the area's rules and ethics on wet rock, closures and permits.
- Wet day? Nearby crags that aren't sandstone, so you can still get your pitches in.
4. Spray some beta
- Local Beta Board: post what you're seeing, like which walls are dry or seeping.
- Get alerts: an email when your area starts drying out (some crags likely climbable), is likely dry again, or turns wet.
It's a guide, not a guarantee
Gauges measure rain, not rock. Shaded, north-facing and seeping rock stays wet longer, and the call can be a sandbag. If the ground is damp, the rock is too. Always check the rock yourself before you tie in. See the terms.
