Quick Answer
The best time to collect dew is typically early morning, shortly after sunrise, when the air is calm and dew has accumulated overnight. In tropical and subtropical climates, dew may be more abundant during the dry season. In cooler climates, dew collection may be more effective during the summer months.
Climate Considerations
In tropical and subtropical climates, the dry season (usually May to October) is the best time to collect dew, as the air is driest and dew forms more readily. In these regions, the best time to collect dew is usually between 5:00 and 7:00 am, when the air is calm and the temperature is still relatively cool.
Temperature and Humidity
In cooler climates, the summer months (June to August) tend to have higher dew points, making dew collection more effective. In these regions, the best time to collect dew is usually between 5:30 and 7:30 am, when the air has cooled overnight and is still relatively humid. In areas with a high diurnal temperature range, such as deserts, dew collection may be more effective during the cooler parts of the day.
Techniques for Effective Dew Collection
To maximize dew collection, use a clean, smooth surface such as a plastic sheet or a tarp, and secure it with weights or rocks. Place the collection surface in a low-lying area to allow dew to accumulate and prevent wind from dispersing it. In areas with high humidity, such as near bodies of water, dew collection may be more effective.
