Know the perfect time to run before you lace up. Real-time conditions, hourly windows, and what-to-wear advice — tailored to you.
The sweet spot for most runners is 45–60°F. It's Nice Out shows how temperature feels with wind chill and humidity factored in — not just the raw number.
A headwind above 15 mph can add minutes to your pace. See current wind speed and direction so you can plan a tailwind on the way home.
High humidity makes runs feel 10–15°F hotter. Our comfort score accounts for this so you know when to ease off or shorten your route.
UV above 6 is a sunscreen moment. We flag high UV and suggest the best morning or evening windows to avoid peak exposure.
Hourly precipitation probability so you know if that afternoon shower will hit during mile 3 or after you're back home.
The hourly forecast highlights the 2–3 hour block each day with the most favorable combination of all conditions for your run.
It's Nice Out suggests layers based on conditions — no more overdressing or arriving at mile 2 wishing you'd worn shorts.
Most runners perform best between 45°F and 60°F (7°C–15°C). At these temperatures your body can dissipate heat efficiently without over-layering. It's Nice Out highlights this range in its comfort score and lets you customize it to your personal preference — some runners love 35°F, others prefer 65°F.
Heat and humidity together are the real risk. When it's 85°F with 80% humidity the "feels like" temperature can exceed 100°F. It's Nice Out's comfort index warns you when conditions are in the danger zone and suggests the coolest window in the morning or evening.
Wind above 20 mph adds significant aerobic load — think 5–10% more effort. Gusts above 30 mph can affect your form and safety. It's Nice Out shows current wind speed and gusts so you can plan accordingly or choose a sheltered route.
Light rain under 50°F can actually feel refreshing. Heavy rain, thunder, or rain combined with cold makes runs miserable and risky. It's Nice Out shows hourly rain probability so you can find a dry window or decide to take the day off.
