You can see the dew point temperature, along with all the latest observations. To check the latest dew point temperature for a given location, open the page for your State/Territory and under ‘Observations’ click ‘latest observations’. We provide current dew point analysis on our website, on the observations page for each State/Territory. Think it will catch on? Viewing dew point observations and forecasts So that old adage might better run, ‘It’s not the heat, it’s the moisture in the air, which at higher temperatures is more reliably indicated by dew point than humidity’. On the other hand, if you’re from southern Australia, you might find these ranges high. If you’re used to the tropics, you may find the ranges in this scale low-particularly during spring and summer where dew points are commonly above 24 ☌. This one uses Brisbane’s climate as an example. How you experience dew point varies, depending on your metabolism and the conditions you’re accustomed to, but it is possible to create an index of how an average person may feel at a certain dew point. So the higher the dew point, the longer it takes for your body to cool itself. When the air is moist, this process slows down-and you feel hotter for longer. One of the ways your body cools itself is by the evaporation of moisture from your skin. In warm, sultry weather, moisture in the air can impede your body’s ability to cool down. How does dew point affect the temperature you feel? For this reason, meteorologists prefer to use dew point when analysing atmospheric moisture and inferring what the conditions may feel like-represented by the apparent (‘feels like’) temperature. Dew point however, is relatively consistent-unless affected by weather systems, such as troughs and fronts. Conversely, if temperature falls, relative humidity rises.īecause of its direct relationship to fluctuating temperature, relative humidity doesn’t provide suitable guidance on how much moisture is available at a specific location. So, if the amount of moisture in the air stays the same but the temperature rises, the relative humidity falls. Relative humidity is the amount of moisture as a percentage of the amount that air can hold-and warmer air can hold more moisture than cooler air. They both measure moisture in the air, but dew point is related to the quantity of moisture, while relative humidity expresses how close the air is to saturation. What’s the difference between dew point and humidity? It represents how much moisture is in the air: the higher the dew point temperature, the greater the atmospheric moisture content. Do you sometimes feel much warmer than the actual observed temperature? ‘It’s not the heat, it’s the humidity’, right? Well not always-at higher temperatures that oppressive, muggy feeling (and frizzy hair) can actually be more about dew point than humidity.ĭew point is the temperature to which air must be cooled in order to produce condensation (dew).
