How we rate your window

7–10 Go5–6 Take care0–4 Skip it

Each window starts at 10 and loses points for heat, rain, thunderstorms, muggy heat, strong sun, gusts, wet roads and poor air quality. Humidity only counts with heat (80% from 28°C, 85% from 30°C), and humidity, dew point and heat stress share one penalty so they don't stack. Thunderstorms or dangerous heat cap it at 4. Separate notes appear for people with asthma or heart conditions; they don't change the score.

Morning window 4:30–7:00 AM, evening window 4:30–6:30 PM, Jamaica time.
