CodClimb gives rock climbers a live 0–100 climbability score for hundreds of curated US
crags — powered by real weather data, not guesswork. And the map keeps growing: climbers
suggest new spots, and verified areas get added for everyone.
WHY CLIMBERS USE IT
Every score is built from five factors that actually matter: temperature, rock dryness
(hours since the last rain), humidity, wind speed, and cloud cover. Tap any crag for the
full breakdown, an hour-by-hour forecast, and a 7-day outlook so you can plan the whole
weekend.
COMPARE CRAGS ACROSS THE WEEK
Deciding where to go? Compare up to three crags day by day in a color-coded grid, tap any
day for the details, and use the hourly overlay to flip between score, temperature, rain,
wind, cloud, and humidity — so you can pinpoint the exact window to send.
LOOK UP — AND PLAN — ANY SPOT
Not every crag is in CodClimb, and new areas appear all the time — so check the live
forecast for ANY location. Long-press the map, use the center crosshair, or type a
latitude/longitude. Save spots as "My points" for one-tap reopening, with the same
hour-by-hour meteogram and an 8–14 day long-range outlook. Arm any saved point for a date
and time window with a purpose — hiking, skiing, surfing, a photo shoot — and get a
pre-trip briefing and a rain heads-up. You can even compare your saved points right
alongside real crags. (Saved points are weather-only — no climb score.)
MAKE THE MAP YOURS
Choose what the map shows with the Layers menu — crags, your saved points, or both. Filter
crags by discipline (sport, trad, boulder, ice), search by name or area, and tap a result
to fly straight to it. Climbed a spot that deserves a crag? Suggest it — if it's added,
you're credited by name on the crag page, and you've grown the map for everyone.

PLAN & GET ALERTED
Set a score alert for your favorite crags, or arm a trip to get a day-before briefing and a
short-range rain heads-up before you make the drive.
A REAL CLIMBING COMMUNITY
See live condition reports from other climbers — rock feel, seepage, crowds, photos, and
beta — and post your own after every session. Sort the feed by most liked or most discussed
to surface the standout shots and the best beta, not just the latest. Share any report as a
clean, branded card to Instagram, Stories, or anywhere. Get notified when someone comments
on your report, and build a climber profile with your home area, the spots you've climbed,
achievement badges, and links to your Instagram and TikTok so climbers can connect.
TUNE IT TO YOU
Adjust how much each factor counts and set your ideal temperature range, so the score
reflects how you climb.
Conditions change fast and forecasts aren't perfect — CodClimb helps you plan, but always
judge the rock in person before you climb.
