“I’ve tried a few weather apps over the years, but RunWeather is the first one actually built for runners, not just generic forecasts. The accuracy is genuinely impressive — temperature, wind, and precipitation timing line up with what I actually experience on my runs, which makes a real difference when you’re planning around rain windows or heat. What sets it apart is how easy it makes run planning: I can quickly see the best time slot for my run based on real conditions instead of guessing from a generic weather app. The interface is clean and intuitive — no clutter, just the information I need at a glance before heading out the door. For the price, it’s excellent value — this has become a permanent part of my pre-run routine. Highly recommended for anyone who takes their training seriously and wants to plan runs around real conditions rather than surprises.”

“Not just the best run planning app for weather I've ever seen, but maybe the best weather app for any activity for going outdoors. See a simple number, tweaked based on your preferences, for who pleasant being outside will be. See all the factors impacting that number based on weather factors that actually matter for comfort. See how the weather will impact your run pace so you can understand how fast you should go. The developer gets it - dew point and sun exposure are as important as temp!”

“i just needed an app to tell me if it's agood time to run and it does that perfectly. I'm just a casual runner so I only use the free version but so far so good, no ads”
Christoph
“Been using the app for a few weeks. I’m a fan. Typically I use the weather app to look at several different data points like temp, dew point, sunrise time, etc. just to set my expectations. RunWeather kind of condenses it all into one screen. Most of all, it’s helped me understand which days I can maybe push my run to after I drop off my kids at school so instead of waking up at 4:40 I can wake up at 6:10. That’s a big difference.”

“While I began running decades ago, having objective data on weather conditions and the impact they have on training/racing is still very valuable.”

The problem

The forecast looked fine. The run did not.

Temperature alone does not explain a hard run. Heat, dew point, wind, and timing all change how a run feels, but most weather apps leave runners to guess.

01

You blamed yourself
for the wrong thing

Sometimes your pace dropped because of conditions, not fitness.

02

You picked the
wrong time to run

A few hours can make the difference between manageable and miserable.

03

You saw the weather,
not what it does to a run

Most apps show the forecast. They do not explain what it means for your effort.

The number

Every run has a weather-adjusted pace.

Heat, dew point, and wind add time to your pace whether you notice or not. RunWeather shows what your run was worth on a neutral day, before you go and after you finish, so a slow run reads as weather and not as lost fitness.

01

Before the run

What weather will add

What today’s heat, dew point, and wind are likely to add to your pace. Pick the hour that adds the least.

02

After the run

What weather added

What the conditions actually added, measured against the run you just finished, not a generic table.

03

Across the season

Your pattern

Which conditions slow you most, learned from your own runs rather than an average runner’s.

A worked example: it feels like 31°C and the dew point is high, so weather adds about +0:18 /km (+0:29 /mi) today. Aim for 5:20/km instead of 5:00 and the effort stays honest. Run Score: 45.

Product

Weather, translated into running decisions

RunWeather helps at three moments that matter: before the run, during interpretation, and across your training history.

Before you go

Pick a better time to run

Compare the hours ahead and choose the window most likely to feel manageable, before heat, dew point, and wind turn against you.

  • Hour-by-hour run suitability
  • Comfort and effort signals for every hour
  • Faster decisions without weather guesswork

Same run. Different effort.

See what made today feel harder

RunWeather breaks conditions into runner-relevant signals, so you can understand whether heat, dew point, wind, or precipitation changed effort more than your legs did.

  • Runner-focused weather signals, not raw forecast noise
  • AI explanations grounded in real weather context
  • Better interpretation of hard, slow, or surprisingly good runs

Across your training

Spot patterns in your history

Sync Strava to connect your running history with the conditions behind each effort, so you can stop confusing weather with fitness changes.

  • Automatic Strava sync
  • Historical weather context for past runs
  • Deeper insights across your training history

Finally answer the question every runner asks: was I off, or was it just the weather?

Why I built it

Built by a runner who got tired of guessing

I run regularly, and I kept hitting the same problem: weather apps showed the forecast, but not what that forecast meant for the run itself. So I built RunWeather to turn weather into better running decisions, with engineering rigor and runner-first thinking.

01

Built by a runner

02

Engineered independently

03

Designed around effort, not generic forecasts

Should I run now, or wait a few hours?

02

Was that run hard because of me, or because of the weather?

03

Do conditions explain my slow runs, without me doing the math?
