The dew point is 60 ☏ (~15.5 ☌), so following the formula, we can find out that the relative humidity is ~60%. Let's take another example: summer finally has come, we are relaxing near a river, and the temperature is 75 ☏ (24 ☌). The temperature at which condensation occurs is called the Dew point and is dependent upon the humidity and pressure of the air.Our forecast shows that the dew point is equal to 40 ☏ as well – so the relative humidity is 100%. Imagine that it's a cold autumn morning, 40 ☏ outside (~4.5 ☌).To better understand the difference between dew point and humidity, let's look at this example: In a particular case, when the air is maximally saturated with water (the relative humidity is 100%), the dew point is equal to the current temperature. Relative humidity is a more confusing value as it depends on temperature and the pressure of the system in question.ĭew point and relative humidity are not the same, but they are closely related: the higher relative humidity is, the closer the dew point is to the current air temperature. Wind west 20 km/h except northwest 40 near the water. If you want to know whether (or weather, heh) it's comfortable or not to have a morning jog or go on a weekend hiking trip – stick with that term. Current conditions and forecasts including 7 day outlook, daily high/low temperature, warnings, chance of precipitation, pressure.

The higher the dew point is, the more moisture that is in the air. Colorado Springs 7-Day Forecast Pueblo 7-Day Forecast Teller County 7-Day Forecast Caon City 7-Day Forecast Download Our Apps. Now that you know the formulas for dew point and humidity, you may wonder, what is the difference between those two terms?ĭew point is an accurate measurement of the moisture content in the air. It is merely the water content in the air, expressed in grams per cubic meter:Ībsolute humidity = m / V, where m is the mass of water vapor, and V is the volume of the air and water vapor mixture.įor saturated air at 30 ☌ (86 ☏), the absolute humidity in the atmosphere ranges from ~0 to 30 grams per cubic meter.ĭid you notice that the formulas don't take the temperature into consideration? To understand this definition, you also need to know the meaning of absolute humidity. Or, expressed differently, the relative humidity is the ratio of the water vapor pressure Pw to the saturation water vapor pressure Pws at the given temperature:
relative_humidity = 100% × current absolute humidity / max absolute humidity, at current temperature.In other words, it's the amount of moisture in the air compared to what the air can maximally "hold" at that temperature: 14 day forecast, day-by-day Hour-by-hour forecast for next week. It is the ratio of the current absolute humidity to the maximum absolute humidity possible for the current temperature.
