However, the beauty of Melbourne's climate is its unpredictability. Some days will be gloriously warm, and you can comfortably spend the day in shorts and a t-shirt.

It's always a good idea to check the detailed weather forecast closer to your travel date to get a more accurate picture of the expected temperature range. This will help you pack the right clothes and plan your activities accordingly. For those who are sensitive to heat, it's essential to take precautions during the hotter days. Stay hydrated by drinking plenty of water, wear light-colored, loose-fitting clothing, and seek shade during the peak hours of the day. Using sunscreen is also a must to protect your skin from the harsh Australian sun. Remember, while the average temperatures provide a general idea, Melbourne's weather can be quite dynamic. Always keep an eye on the latest weather updates to stay informed and enjoy your trip safely. If you are planning to spend a lot of time outdoors, consider carrying a portable fan or a spray bottle with water to keep yourself cool. This will enhance your comfort and help you make the most of your time in Melbourne during the warm December days.

Rainfall and Sunshine: What to Expect

Let's talk about sunshine and rain, because, hey, what's Melbourne weather without a bit of both? December is generally a drier month compared to spring and autumn. You can expect around 5-7 days of rainfall throughout the month. However, don't let this low number fool you! Melbourne's showers can be short but intense. It's not uncommon to experience a sudden downpour in the afternoon, followed by clear skies and sunshine. The average rainfall for December is around 50-60mm, so it's not a deluge by any means. Sunshine hours are plentiful in December, with an average of 8-10 hours of sunshine per day. This means you'll have plenty of daylight to explore the city, enjoy outdoor activities, and soak up the Vitamin D. The combination of sunshine and occasional rainfall creates a vibrant and lush environment. The city's parks and gardens are particularly beautiful in December, with flowers in full bloom and greenery thriving. Pack accordingly! While you might not need an umbrella every day, it's wise to carry a compact one or a light rain jacket, just in case. Waterproof shoes or sandals can also be helpful. The sudden rain can sometimes create puddles, so having appropriate footwear can save you from wet feet. The sun can be intense, so don't forget your sunscreen, hat, and sunglasses. Even on cloudy days, the UV index can be high, and it's essential to protect your skin from sun damage. Keep an eye on the weather forecast to get an accurate idea of the predicted rainfall and sunshine hours for your specific travel dates. Websites and weather apps will often provide hourly or daily forecasts, including information on the chance of rain, wind conditions, and UV index. The sun's position is also an important factor in December. The sun rises early and sets late, providing extended daylight hours. Plan your activities accordingly, taking advantage of the long days to explore the city and enjoy the outdoors. The extended daylight also means that sunsets are later, offering beautiful opportunities for photography and enjoying the city's scenic spots.

Wind Conditions: Breezy or Calm?

Melbourne's wind conditions in December can vary quite a bit. You might experience calm, still days, perfect for outdoor activities, or breezy days with a refreshing wind. Generally, the wind speeds in December are moderate, averaging around 15-25 km/h (9-16 mph). However, stronger winds are possible, particularly during the afternoons or when a cold front passes through. These stronger winds can make it feel cooler, especially if the wind is coming from the south. The wind direction also plays a role in how the weather feels. Southerly winds tend to bring cooler air, while northerly winds can bring warmer air. Coastal areas, such as St Kilda and Brighton, are often more exposed to the wind, so be prepared for potentially gusty conditions. Checking the wind forecast before you head out is always a good idea. This information will help you dress appropriately and plan your activities. On windy days, you might want to consider wearing a light jacket or a windbreaker. If you're planning to spend time at the beach, be mindful of the wind conditions. Strong winds can create choppy waves, making it less ideal for swimming or other water activities. The wind can also affect the temperature, making it feel cooler than the actual temperature. This is especially true if you are exposed to the wind for an extended period. The wind can also cause the sand to blow around, so it is a good idea to use a beach umbrella or a windbreak. Melbourne's weather is known for its variability, and the wind is no exception. It is important to stay flexible and adapt your plans accordingly. If the wind is too strong for certain activities, consider finding an alternative indoor option or visiting a sheltered location. The wind can also affect the UV index, so make sure to protect your skin from the sun. The wind can sometimes create a cooling effect, but it doesn't mean you are immune to sunburn. Remember to apply sunscreen and wear protective clothing.
