Excellent conditions for any outdoor activity. Go enjoy the day!
What We Consider
Temperature
18–24°C is ideal. We factor in perceived temperature from wind and humidity.
Wind Speed
Under 15 km/h is comfortable. Above 30 km/h affects most activities.
Humidity
35–55% is optimal. High humidity makes heat oppressive.
UV Index
2–5 is moderate. Above 7 requires sun protection.
Precipitation
Under 10% is ideal. Above 50% suggests indoor backup plans.
Overall Score
All factors combine into a single 0–100 actionable score.
Frequently Asked Questions
What makes a good day to go outside?
A good outdoor day combines comfortable temperature (18–24°C), low wind (<15 km/h), moderate humidity (35–55%), manageable UV (2–5), and low precipitation chance (<20%). Our Outdoor Comfort Index weighs all five factors into a single 0–100 score.
What Outdoor Score means perfect weather?
A score of 80+ indicates perfect conditions for virtually any outdoor activity. Scores between 60–79 are great for most activities. Between 40–59, conditions are acceptable but not ideal. Below 40, outdoor time may be uncomfortable.
How does UV index affect outdoor comfort?
UV index measures sunburn risk. A UV of 2–5 is moderate and comfortable for extended outdoor time. Above 7, you need sunscreen reapplication every 90 minutes and shade during peak hours (11 AM–3 PM). Above 10 (extreme), limit outdoor exposure.
Should I go outside if rain chance is 40%?
A 40% precipitation chance means conditions are uncertain. Short outdoor activities close to shelter are fine, but avoid committing to long hikes or events without rain gear. Our score accounts for this uncertainty automatically.
What is the best time of day to go outside?
Generally, mid-morning (9–11 AM) and late afternoon (4–6 PM) offer the best balance of warmth, lower UV, and settled weather. Midday is warmest but has highest UV. Early morning and evening are coolest with best light for photography.

Making the Most of Your Outdoor Time
The question "is today a good day to go outside?" seems simple, but the answer depends on more than temperature. Wind chill can make a mild day feel cold, high humidity makes moderate temperatures oppressive, UV radiation determines safe sun exposure time, and precipitation probability affects whether you'll get wet.
Our Outdoor Comfort Index synthesizes all five key weather variables into a single, actionable score. A score of 80+ means conditions are ideal for virtually any outdoor activity — hiking, cycling, dining al fresco, or simply sitting in the park. Between 60–79, conditions are comfortable for most activities with minor adjustments. Below 40, you may want to reconsider or choose sheltered alternatives.
