Klimat Passes 80 Million Strava Weather Activities

Klimat has just processed its 80 millionth Strava activity. That’s a good excuse to revisit our coverage, last updated back in 2020.

---

For those unfamiliar, Klimat is a third-party app that syncs with Strava to add detailed weather data to your activities. It fills a gap that Strava itself has never properly addressed — the platform’s built-in weather has always been bare-bones at best. A temperature number, occasionally wrong. A weather icon. Zero context.

If you’re trying to understand why a run or ride felt harder than expected, Strava’s weather is basically useless. Klimat fixes that. Not by predicting your next PB or telling you how to train, but by doing one thing well: adding complete and meaningful environmental context to your activities.

Six years on, what’s changed is that Klimat is now much better at staying useful without getting annoying.

Weather Across the Whole Activity, Not Just the Start

The original idea was simple: add weather to your activity. The problem was execution. Early versions mostly captured conditions near the start, which is fine for a 30-minute jog and misleading for almost everything else.

Klimat now samples conditions across the entire activity: start, middle, and end. You get minimums, maximums, and the changes you actually experienced.

This matters on long runs, exposed rides, or anything where the second half feels nothing like the first. Instead of relying on memory, the conditions are right there in the log.

Air Density for Runners and Cyclists: Why It Matters

Air density sounds niche, and it is. It’s also one of the more sensible additions.

It combines temperature, pressure, and humidity into a single value that affects aerodynamic drag (CdA) and, to a lesser extent, oxygen availability. Cyclists have cared about this for years — it’s why hour records are often attempted at altitude. Runners probably should pay attention too, at least occasionally.

The important part isn’t the metric itself. It’s that Strava doesn’t show it, almost no one would calculate it manually, and Klimat does it automatically and consistently.

Over time, it becomes another useful reference point when comparing similar efforts that didn’t feel the same.

Multiple Weather Providers: Choose Your Data Source

Multiple weather providers offer the choice of the best local source, fix real problems.

Weather accuracy varies a lot by location, especially for wind. Klimat lets you choose your provider rather than forcing everyone onto a single source – Accuweather, Apple Weather, the Weather Channel…

If you’ve ever looked at Strava’s weather data and thought “that’s just wrong,” this is why Klimat’s data tends to be more trustworthy.

Air Quality Data Without the Drama

Air quality data is included, and importantly, it’s not shoved in your face.

No warnings. No moralising. Just data.

That’s enough to explain why breathing felt harder, why perceived effort was higher, or why pace didn’t match heart rate. It’s far more useful when you’re reviewing training later than when you’re mid-run anyway.

Templates: Control What Appears in Your Activities

One of the better decisions Klimat has made is templates.

You decide what appears, how much detail you want, and how readable your activity description stays. This avoids the common third-party app mistake of turning Strava activities into unreadable walls of data. If you care about clean logs, this matters.

FAQ

Q: Is Klimat free?

A: Klimat is free for 90 activities then $15 a year afterwards

Q: How is Strava’s weather different

A: Strava adds basic local weather info at the start of your activity (temperature, wind speed, and precipitation).

Q: What alternatives are there?

A: There is the existing free Strava info plus paid alternatives from myWindsock and Strautomater

Q: Is Strava likely to improve its weather reporting?

A: It hasn’t changed weather reporting for many years and is unlikely to. Strava is embarking on an IPO process in 2026 and recruiting heavily, some jobs were linked to mapping but none to weather.

Verdict

Klimat won’t tell you what to do next or how fit you are. It isn’t a training platform.

What it does is answer a much simpler question: “What exactly were the conditions?”

By sampling weather properly, adding genuinely useful environmental metrics like air density and air quality, and staying visually out of the way, it does that job better than Strava itself.

80 million activities suggests plenty of other athletes agree – 180,000 in fact!

Not exciting. Not flashy. Just useful — which, frankly, is the point.
