Comparison
RunWeather vs Garmin weather for runners
Garmin's weather is a forecast on your wrist plus conditions logged on your activities; it does not judge conditions for running. RunWeather scores every hour 0-100, finds your best window, and explains how heat, dew point, and wind will slow your pace. The two are complements: Garmin measures the run, RunWeather times and explains it.

| Platforms | iOS and Android | Garmin devices + Connect app |
Garmin watches and Garmin Connect are outstanding at measuring your running: pace, heart rate, training load, readiness. The weather side is thinner: a basic forecast widget on the watch and a temperature stamp on completed activities.
What Garmin doesn't try to answer is whether 6am or 6pm is the better run today, how much the dew point will slow you, or whether WBGT heat strain has crossed a safety line. That interpretation layer is what RunWeather adds, and with optional Strava sync it also back-fills weather context onto the runs your Garmin recorded.

When Garmin alone is enough
If you run by schedule rather than by conditions, the watch forecast tells you what to wear and that's genuinely all you need. Garmin's strength (physiology and training metrics) is untouched by anything RunWeather does.
When RunWeather earns its place
If your Garmin says a run was hard but not why, conditions are usually the missing variable. RunWeather adds the weather layer: score the hours before you head out, pick the window, and see the dew point and heat strain behind every logged run. Connect Garmin once and every run you record syncs on its own.

Common questions
3 questionsDoes RunWeather connect to Garmin?
Yes. Connect Garmin and every run you record syncs on its own. Strava and Apple Health work too.
Does Garmin show dew point or WBGT?
Garmin's forecast widget shows temperature and general conditions; it does not surface dew point or WBGT heat strain for running decisions. RunWeather treats both as first-class inputs with published safety thresholds.
Do I need both?
They answer different questions. Garmin measures your body and your run; RunWeather scores the conditions and picks the window. Runners who train through summer typically use both.
