Keynote: Are Evaporative Coolers Good in Melbourne?

Evaporative coolers are a viable option for Melbourne due to the city’s often dry and hot summers. They work best in low humidity, providing energy-efficient cooling. However, on humid days, their effectiveness can decrease. Always consider the day’s weather before use.

Melbourne’s Climate and Its Effect on Cooling Systems

Melbourne, renowned for its ‘four seasons in one day’, showcases a diverse climate. Summers, from December to February, generally experience high temperatures ranging from 25-35°C. While winter months, from June to August, see temperatures drop to an average of 6-15°C.

Annual rainfall is moderate, with an average of 603mm per year, spread fairly evenly across all seasons. However, relative humidity varies throughout the year, usually around 50% in summer and peaking at around 80% in the cooler months.

The Dance of Humidity and Evaporative Coolers

An essential factor to consider while choosing a cooling system is the impact of humidity on its effectiveness. Here’s where the science kicks in: Evaporative coolers function by using the evaporation of water to cool the air, which works best in arid conditions. When the humidity levels rise, the air holds more moisture, limiting the amount of evaporation and thus the effectiveness of the cooler.

The Significance of Climate Consideration in Cooling System Selection

Choosing a cooling system isn’t a one-size-fits-all decision. It’s a complex process that should take into account several factors, including the local climate. This is especially pertinent for evaporative coolers, given their sensitivity to humidity levels.

In Melbourne’s case, with its moderate humidity levels particularly in the summer months, one might wonder if evaporative coolers are a viable option. Well, hold your curiosity, as we delve deeper into the strengths and potential limitations of evaporative coolers in Melbourne in the next section.

Weighing the Pros and Cons: Evaporative Coolers in Melbourne

Benefits of Using Evaporative Coolers in Melbourne

Evaporative coolers are gaining traction in Melbourne for good reasons. Let’s highlight some key benefits:

  • Environmental Impact: Evaporative coolers are more eco-friendly compared to traditional air conditioners. They don’t emit harmful greenhouse gases and utilize a natural process of cooling, contributing to lower carbon footprints.
  • Energy Efficiency: Evaporative coolers consume less energy than standard air conditioners, up to 75% less according to the Department of Energy and Environment. This means reduced energy bills, offering considerable savings over time.
  • Cost: The upfront costs of evaporative coolers are lower than that of conventional AC units. Also, their operational costs tend to be lower due to the reduced energy consumption.

Drawbacks of Using Evaporative Coolers in Melbourne

Like any technology, evaporative coolers have some potential drawbacks, especially in Melbourne’s climate:

  • Performance during Humid Days: As mentioned earlier, the cooling efficiency of these systems can decline on particularly humid days. With Melbourne’s humidity averaging around 50% in summers, the cooling effect might not be as powerful on some days.
  • Maintenance Requirements: Evaporative coolers require consistent maintenance to keep them running efficiently. This includes regular cleaning of pads and water tanks to avoid the growth of mould or bacteria, and ensuring the water supply line is in good working condition.

Melbourne Residents Share Their Evaporative Cooler Experiences

Nothing beats first-hand accounts when it comes to understanding the effectiveness of a product. Let’s hear from some Melbourne residents who have chosen evaporative coolers as their primary cooling method.


Sandra, a resident of Melbourne’s inner north, states, “I’ve had my evaporative cooler for three summers now, and it’s been a game-changer. It keeps my home comfortable even on hot days, and I’ve noticed significant savings on my energy bills.

On the other hand, David, from Melbourne’s eastern suburbs, offers a different perspective. “It’s great most of the time, but I did find its performance dropped on a few really humid days. However, the cost savings and the environmental benefits make it worthwhile for me.

Analysis of Experiences Across Different Seasons

  • Summer: Most users report satisfactory performance during most summer days. However, as David mentioned, the effectiveness can drop on extremely humid days.
  • Spring/Autumn: These seasons typically have moderate temperatures and lower humidity levels in Melbourne, and users report excellent performance of their evaporative coolers during these periods.
  • Winter: Although evaporative coolers are not designed to function as heaters, some users mentioned that the increased humidity slightly increased perceived warmth during colder months. However, this is not a primary function and should not be relied upon.

These testimonials and seasonal analysis show that while evaporative coolers may have limitations, many Melbourne residents find them a satisfactory and cost-effective solution to their cooling needs.

Are Evaporative Coolers Right for Melbourne?

Beyond the experiences of everyday users, it’s crucial to gather insights from professionals who work with these systems daily. Let’s look at what HVAC (Heating, Ventilation, and Air Conditioning) experts in Melbourne have to say about evaporative coolers.
