Melbourne Environmental Conditions


Melbourne weather is variable, to say the least.  Detractors claim, and Melbournians proudly agree, that here you can experience four seasons’ weather in one day.


The maximum daily temperature in November has ranged between a low of 27.7oC (81.9oF) and high of 41.6oC (106.9oF) with a mean of 33.6oC (92.5oF)

Minimum temperatures are between a low of 0.9oC (33.6oF) and a high of 6.9oC (44.4oF), with a mean of 4.7oC (40.5oF).

Humidity, Rainfall & Wind

The average relative humidity in November is 68%, with an average rainfall of 43mm (1.69″) spread over an average of 13.5 rain days.  Average windspeed is 11.1 km/hr (6.9 mph).

Day Length, Sunshine and UV Index

In Melbourne, the average length of the day in November is 14.2hrs with an average of 8.5 hrs of sunshine, and the average daily maximum UV index is 5.   A UV Index value of 3 to 5 symbolizes a medium health risk from the exposure to the Sun’s UV rays and sun protection is advisable.

Pollen & Hay Fever

The most common cause of hay fever in Victoria is from grass pollen, which is prevalent

in October to December, peaking in the latter half of November, then diminishing during December (see graph).  As the Victorian Croquet Centre is in the western part of Melbourne with grasslands to its west and the predominant winds being westerlies, those susceptible to hay fever are advised to ensure that they have appropriate medications available.

Thunderstorm Asthma

Melbourne experienced the world’s largest epidemic thunderstorm asthma event in November 2016, (see for details) which affected thousands.

The Victorian Department of Health has developed a thunderstorm asthma forecast available at and on a high risk day the department will issue up-to-date relevant advice and warnings on the VicEmergency warning  platform which is available as an app for both Android and Apple phones & tablets.
