Here's a practical approach for a typical spring weekend:

• Morning (cool, maybe dew): Close the airflow about 70% of the way. You'll get a concentrated hit that warms you up.
• Midday (sunny, warm): Open it halfway. Balanced vapor, still flavorful, but cooler.
• Afternoon (warm, maybe some wind): Open it nearly full. You want a cool, airy draw that doesn't feel heavy.
• Evening (cool again): Close it back down to 70% or even 50%.

Remember, you're not locked into one setting. Adjust as the temperature changes and see what feels right.
