Hiking in the Rain: What Actually Keeps You Safe

Hiking in the rain isn't just damp and miserable — it's the weather where hypothermia actually happens. What to wear, how to keep your footing, and what your phone's water rating really covers.

Rain doesn't cancel a hike the way cold or heat does — most of the time it just makes people decide at the trailhead, soaked already, whether to turn around. The weather itself is rarely the problem. What it does to your clothing, your footing, and your judgment over a few hours is the part that actually causes trouble, and almost all of it is avoidable with choices made before you leave the car.

This is the research-based version of what to do differently, built on published guidance from land managers and outdoor organizations rather than one person's opinion of what worked for them once.

Is hiking in the rain actually dangerous, or just unpleasant?

It can be genuinely dangerous, and the risk isn't really about rain — it's about what rain does to your body temperature. Rocky Mountain National Park's own guidance is blunt that hypothermia "can happen year-round, even on nice sunny days," and cool, wet, and windy is the exact combination that causes it, well above freezing.

That reframes the whole question. The discomfort of being wet is the part hikers brace for; the part that actually hurts people is a body that's been losing heat for hours without anyone noticing, because nobody feels cold the way they expect to feel cold — they feel clumsy, tired, and irritable instead.

What should you wear hiking in the rain?

Layers that aren't cotton, with a waterproof shell on top. The Washington Trails Association's rainy-season guidance is specific: a wool or synthetic base layer against your skin to wick moisture away, an insulating layer like fleece, and a waterproof-but-breathable rain jacket on top, with rain pants or a rain wrap over your hiking pants.

Cotton is the thing to actually eliminate, not just minimize — it soaks up water and stops insulating once wet, and it dries slowly enough to stay a problem for the rest of the day. The Appalachian Mountain Club's rain-gear advice adds the detail most people miss on the jacket itself: cuffs that seal tightly at the wrist, with your base-layer sleeves pushed up away from them, because loose cuffs are where water tracks up your arm under a jacket that's otherwise doing its job fine.

How do you keep your footing on wet trails?

Grippy soles, trekking poles, and more attention than you'd give a dry trail. WTA's guidance calls out watching your footing specifically "around any steep drainages, along hillsides, some shorelines and on snowfields" once rain picks up, and notes that terrain near recent fire activity gets particularly unstable to mud and debris flows in heavy rain.

Poles earn their weight here — they're not just for balance on a flat wet log, they're a second and third contact point on exactly the slick rock and root sections where a boot alone isn't enough warning before it slips. Slow down on anything downhill: gravity turns a slip into a fall fastest on the way down, and that's exactly where the extra contact point helps most.

What should you do if a creek crossing looks higher than you expected?

Don't cross it, and don't assume it'll be the same height on the way back. WTA's advice is to "carefully assess any creek or river crossings" specifically because rain swells them unpredictably, fast enough that a crossing that was manageable on your way in can be a different, more dangerous crossing two hours later on your way out.

If a crossing looks wrong, the honest options are wait, find another way, or turn back — not push through because you've already come this far. A creek with brown, fast-moving water carrying debris is telling you something concrete, not being dramatic.

Can you get hypothermia hiking in the rain even when it's not that cold?

Yes, and that's the specific trap rain sets that dry cold doesn't. Rocky Mountain National Park lists the warning signs as uncontrolled shivering, slow or slurred speech, memory lapses and incoherence, fumbling hands, and stumbling or drowsiness — a progression that looks a lot like someone just being tired and grumpy until it doesn't.

The guidance that matters most here is the strategy, not the symptom list: "avoid getting chilled and wet" in the first place, because recognizing hypothermia in yourself gets harder exactly as it gets worse — the part of your brain that would notice is the part losing function first. If someone in your group gets quiet, uncoordinated, or stops making sense, that's the moment to stop and warm them up, not the moment to debate whether it's really hypothermia.

Is your phone safe to use for GPS tracking in the rain?

Mostly, but its water rating covers less than people assume. Apple's own iPhone specification lists an IP68 rating — "maximum depth of 6 meters up to 30 minutes" under lab conditions — with a footnote that matters more than the number: "splash, water, and dust resistance are not permanent conditions. Resistance might decrease as a result of normal wear."

Rain itself is a mild case next to that spec. What the rating explicitly doesn't cover is pressurized or fast-moving water, and ordinary rain hitting a phone in your hand isn't that either — the bigger practical risk on a wet hike is a touchscreen that stops responding reliably when it's wet, not water getting inside. Keep it in a pocket or a dry bag when you're not using it, and dry the screen before you need to tap anything in a hurry.

The part that works regardless: GPS reception doesn't need a dry phone or even a signal, so a route recording in TrailsPals keeps logging your track through rain and dead zones the same way it does on a clear day. How to record and relive a hiking route covers the permission to get right so that keeps working in the background.

What should you pack specifically for a rainy day hike?

Beyond your regular day-hike checklist: a pack cover or a liner bag inside your pack, a dry set of socks sealed away from everything else, and a few extra minutes built into your turnaround time. Wet feet are more blister-prone feet, and dry socks at the car — or at a lunch stop — are one of the cheapest comfort upgrades available.

Food and water matter more than they do in good weather, not less. It's tempting to eat and drink less often in cold rain, since stopping means getting colder for a minute — but that's backwards: your body is working harder to stay warm and needs the fuel on a schedule, not whenever a dry rock happens to show up.

Should you still tell someone before a rainy hike?

Yes, and arguably more than usual — a slower, more cautious pace in bad weather means your actual return time slides later than a clear-day estimate, and that's exactly the gap that turns a late hiker into an unnecessary search if nobody adjusted for it. Build the weather into the return time you give someone, not just the distance.

That's the plan-before-you-go half of this, not the gear half, and it's worth treating as seriously: who has your route, what time means "something's wrong," and what they do about it. Our hiking safety app page covers how TrailsPals handles the expected-return-time and overdue-check-in side of that, and how live location sharing works on the trail covers what a watcher actually sees if the weather turns and you're slower than planned.

Rain is one of the few hazards you get real warning about — a forecast, a darkening sky, a trailhead sign-in board other people already turned around at. Most of the advice above is just using that warning properly: dress for the water, not the temperature on the forecast; move deliberately on the terrain it changes; and make sure the time you gave someone at home still means something if the hike takes longer than it would have in the sun.
