Conditions ranked 1–10 for each activity using National Weather Service forecast data — temperature, wind, humidity, and rain scored for what actually matters to each sport.
Each activity uses a tailored weather index — scoring the conditions that matter most for that sport.
Each index is built from NWS forecast data — weighted differently based on what actually matters for that sport.
Temperature peaks at 60–75°F. Wind penalized sharply above 15 mph. Partly cloudy scores highest.
Similar to golf but wider temperature tolerance. Wind and rain are the primary penalties.
Cooler temperatures score best. Dewpoint heavily penalized — the key factor for runners.
Wind direction and speed are critical. Temperature range broader than running. Rain penalized heavily.
Overnight lows, rain probability, and wind combined. Scored for both day and night comfort.
Rain probability weighted heavily. Wind penalized sharply above 15 mph. Visibility included for fog risk.
Air temp, cloud cover, and ocean water temperature combined. Coastal locations only.
Cloud cover is dominant. Low humidity and low moon illumination also scored. Light pollution included.
Temperature, wind, and rain scored across a wide comfort range. Trails and national park locations prioritized.
Outdoor activities are highly sensitive to weather, and the factors that matter differ significantly by sport. A perfect day for running — cool, dry, overcast — is very different from a perfect day for golf or a day at the beach. Just Right Weather's activity indexes capture those differences, scoring each city on the variables that actually affect enjoyment and performance.
All activity indexes are built from National Weather Service forecast data at 2.5km grid resolution across the contiguous United States, updated daily. Scores run from 1 (poor conditions) to 10 (ideal conditions).
The Perfect Weather Index captures general outdoor comfort — conditions most people would describe as "nice" regardless of what they're doing. Activity-specific indexes refine that further. A city might score 8.5 on the general PWI but only 6.0 for cycling if winds are sustained above 20 mph. Use the 7-Day Weather Maps for overall planning, and the activity pages when you have a specific sport in mind.
