A single 0–100 score per crag, weighted by temperature (30%), dryness (25%), humidity (20%), wind (15%), and cloud cover (10%). No more guessing.
CORETap any factor to expand a plain-English explanation and see exactly how much it contributes — weight %, factor score, and points added to your total.
NEWSee exactly how many hours ago it rained and get a warning banner when rain is approaching — so your limestone stay dry when you show up.
CORECodClimb automatically ranks your saved crags by the best Saturday and Sunday forecast windows. Just show up and climb.
COREBrowse every crag on a live map with color-coded score pins that cluster at national zoom. Green means go, red means rest day. Tap any pin for instant conditions.
COREPrefer full sun or cooling shade? Set your sky preference in Settings and the cloud cover score flips to match — great for hot summer granite or alpine routes.
NEWClimbers post real-time condition updates with up to 4 photos per report. Seepage, rockfall, fixed gear status — straight from the crag.
UPDATEDSet a score threshold for your home crag and get a notification the moment conditions cross it. No more checking every morning before a long drive.
COREAfter sunset the score card automatically shows tomorrow's forecast window instead of tonight's useless score. Plan tonight, send tomorrow.
COREFilter by discipline — sport, trad, boulder, or ice — plus rock type, sun exposure, and region. Find exactly the limestone sport crag with south-facing sun on a cold October morning.
CORENot bothered by wind? Obsessed with dryness? Dial in each factor's weight to match your style. Presets for sport, trad, and bouldering included.
NEWAsk beta directly on a report, clarify ambiguous conditions, or confirm a send. Threaded comments make the community feed an actual conversation.
UPDATEDFor crags with mixed wall types, CodClimb scores Exposed (slab, face) and Overhang (cave, roof) separately — overhangs ignore rain and win on wet days.
NEWDrag an hour-by-hour timeline to see when a wall is in sun or shade today — computed from the crag's aspect and the sun's path. Plan the cool window or chase the sun.
NEWFlag inappropriate posts with one tap. Posts are auto-hidden after community reports and reviewed by the CodClimb team within 24 hours.
NEWEach crag has a seasonal calendar showing its best months and whether May is peak season or a scorcher. Plan the whole year, not just the weekend.
NEWThe 0–100 score is built from five real weather factors, each weighted by how much it actually affects climbing. Not a black box — tap any factor in the app to see exactly what's driving your score.
Ideal temperature: 55–68°F. Dryness clock starts after the last rain and hits 100% at 24h. Wind sweet spot: 5–15 mph. Cloud cover adapts to your sky preference.
Weather data tells you what the atmosphere is doing. Community reports tell you what the rock is actually doing. The two together give you the full picture before you drive three hours.
Show the seep, the crowd, the conditions — from multiple angles.
Browse reports only from New England, Mid-Atlantic, Southeast — wherever you're headed.

The same idea, now for the winter. CodClimb Snow gives 230+ ski resorts worldwide a live 0–100 snow score, built from fresh snow, temperature, wind and visibility, so you can see which mountain is getting the storm before you drive.

One 0–100 number per resort, from fresh snow, temperature, wind and visibility, multiplied by whether there's a snowpack at all. Tap it for the full breakdown in plain English.
A ski score for every day of the week, with the best day called out and a confidence dot on each one, because forecasts get shakier after about day 3.
An hourly ski score and today's best window, plus a full meteogram with temperature, snowfall, wind, cloud and humidity for every hour.
Where the snow line sits, whether it's snow or rain at the summit, mid and base, snow quality from the snow-to-liquid ratio, and when the sun hits which faces.
The last 24 hours, 7 days, 30 days and season to date for every saved resort, with daily snowfall bars and a 14-day outlook.
Pick 2–8 resorts and line them up: next snow, snow by elevation, snow line, quality, a daily score grid and an hour-by-hour chart.
All-mountain, Powder, Cruiser, Park & pipe or Alpine. Pick what counts most for you. It's kept separate from your climbing weights.
Every resort on one map. Filter by region, alpine terrain or night skiing, or by pass: Ikon, Epic, Indy and independents.
Star your resorts to see the best one right now and the best day this week. Arm a powder alert to get a push when your amount of new snow is forecast.
Every resort is scored on the same four factors. A rider profile changes how much each one counts, and the snowpack multiplies the result, so a bare mountain can't score well on a nice day.
× Snowpack: multiplies everything above. No snow on the ground, no score.
Weights shown for the default All-mountain profile. Switch profiles in the app:
