Litchfield National Park is one of the most beautiful areas near Darwin in the Top End. The cooler weather is to be had during the dry season, which runs from May to October. Although some locals believe the shoulder month of April is the ultimate time for a camping experience without the crowds of the peak season.

In this study we aim to answer the question whether and to what extent human-induced climate change has altered the likelihood and intensity of fire weather risk in the southeastern Australian bushfires in 2019/2020. We further aim to answer the same question for two key components of fire weather, extreme high temperatures and lack of rainfall. The study was conducted using a well-established protocol that was used in many previous extreme event attribution studies. In this, we compute the change in probability of a Fire Weather Index, extreme heat or drought as high as was observed in 2019/20 in the current climate compared to the climate of around 1900 in both observations and climate models.

Over half of New South Wales has an arid or semi-arid climate. The eastern portion has a temperate climate, ranging from humid subtropical from its northern border to the Central Coast and most of Sydney, and oceanic to the south coast. The Snowy Mountains region in the south-east falls in the alpine climate or subpolar oceanic climate zone, with cool to cold weather all year around and regular heavy snowfalls in the winter and spring. Further inland, the climate is semi-arid and a desert climate towards the western part of the state.

The weather in the southern half of the state is generally warm to hot in summer and cool in the winter. The seasons are more defined in the southern half of the state, especially in the South West Slopes, Central West and the Riverina regions. On the coast and anywhere east of the dividing range, a summer rainfall peak is observed throughout its entire latitudinal span. On the ranges and farther inland, rainfall usually peaks in spring in most parts of the state; though the South West Slopes region, in the south-central part of the state (bordering Victoria), has a distinct winter rainfall peak; whereas the New England and North West Slopes regions have a summer rainfall peak. On a hot summer day, a southerly buster may at times moderate the extreme heat experienced in the coastal New South Wales region, from Port Macquarie southwards to Nowra.[10]

The warmest region by annual maxima is the north-west, where summers are extremely hot, but winters relatively cooler and dry. The weather in the northeast region of the state, or the North Coast, bordering Queensland, is moderately hot, humid and rainy in the summer, and mild in winter with more sunshine; and little seasonal temperature difference. The Northern Tablelands have relatively milder summers and colder winters, due to their high elevation and inland location on the Great Dividing Range. The southeast coastal plain, which lies on the leeward side of the Great Dividing Range, experiences foehn winds, particularly between winter and spring, which can elevate fire danger.[11]

However, most of the Queensland populace experience two weather seasons: a winter period of rather warm temperatures with minimal rainfall, and a sultry summer period of hot, sticky temperatures and more rain.

Tasmania has a cool temperate climate, with most areas under an oceanic climate (Cfb), with four distinct seasons. Summer lasts from December to February when the average maximum sea temperature is 21 C (70 F) and inland areas around Launceston reach 24 C (75 F). Other inland areas are much cooler; Liawenee, located on the Central Plateau, is one of the coldest places in Australia with February temperatures ranging between 4 and 17 C (39 and 63 F). Autumn lasts between March and May and experiences changeable weather, where summer weather patterns gradually take on the shape of winter patterns.[48]

Heavy rainfall is bringing more dangerous flooding to Australia. The Bureau of Meteorology has issued a severe weather warning for Western Australia, and officials say once-in-a-century flooding has hit areas in the north of the state.

The Pacific islands have applauded the announcement from the Government of Australia, pledging its support for a long-term solution to weather-related extreme events posed by climate change in the Pacific through the Weather Ready Pacific Decadal Programme of Investment.

The Bureau and CSIRO have worked with the Australian Government to develop a national forecasting system for weather and climate, tailored to Australian needs. This system is called The Australian Community Climate and Earth-System Simulator.

Widespread coral bleaching was observed over the Great Barrier Reef, Australia, the world's largest coral reef during the 2021-2022 La Nia. This raised concerns that background global warming may have crossed a critical threshold causing thermal stress to corals during a climate state historically associated with increased cloud cover, rainfall and cooler summer water temperatures. Here we present an analysis of recent summer La Nia events focused on their synoptic meteorology and corresponding water temperatures over the Great Barrier Reef. Results show that the 2021-2022 summer La Nia caused accumulated coral heat stress to exceed previous La Nia conditions by 2.5 times. We find that weather patterns that favoured the build-up of heat in water overlying the Great Barrier Reef during the 2021-2022 summer were likely the result of repositioning of planetary scale atmospheric longwaves. This insight provides an additional means to predict potential future atmospheric conditions that increase the risk of extremely high water temperatures and coral bleaching in the Great Barrier Reef.

Since January 2020 almost 788,000 claims related to floods and storms declared Insurance Catastrophes or Significant Events have been received by insurers, meaning that in just three years one in 25 adult Australians has made an insurance claim because of this wild and wet weather.

Each one of the 788,000 wild and wet weather claims lodged with insurers over the past three years represents a significant disruption to an Australian homeowner, tenant, landlord, business owner, primary producer or motor vehicle owner.

Have a plan. Watch weather forecasts and know who to call if you need help. When you are going out for the day, ensure you take your medications, a hand-held fan and plenty of water. Talk with your treating healthcare team about how you can live well through the hotter months.

Winter can be a challenging time for people living with a lung condition as temperatures drop and the air becomes cold and dry. Cold weather can trigger a flare-up of your symptoms and make you more vulnerable to illnesses, particularly when there are more viruses and bugs.

The significance of atmospheric blocking as an important climate driver for southern Australia is now more broadly recognized (McIntosh et al. 2008). Individual occurrences of blocking are influenced by the configuration of the atmospheric longwaves around the Southern Hemisphere at any time, but their onset and maintenance in the Australasian region is not fully understood and is poorly simulated in climate models (Palmer et al. 2008; McIntosh et al. 2008). Blocking is partly predictable in numerical weather prediction models (Tibaldi and Molteni 1990) but less so in extending to intraseasonal time scales (Watson and Colucci 2002). The Tasman Sea and southwest Pacific sector is the dominant region for blocking to occur in the Southern Hemisphere, and there is a maximum frequency of occurrence near southeastern Australia in winter (Coughlan 1983; Pook and Gibson 1999).

The Bureau of Meteorology has confirmed that another El Nio event is underway in Australia. As climate change continues to supercharge our weather, the impacts on natural climate phenomena like El Nio become increasingly significant.

While its counterpart, La Nia, brings wetter and cooler conditions to much of Australia, El Nio often heralds drier and hotter weather. An El Nio event can intensify heat waves, increase the severity of bushfires, and contribute to drought conditions. The influence of El Nio is primarily felt in eastern Australia, resulting in warmer-than-usual temperatures and reduced rainfall. This combination not only heightens the risk of extreme heat but also elevates the danger of bushfires, particularly in southeastern regions.

The Bureau of Meteorology has also declared that a positive Indian Ocean Dipole is underway. The Indian Ocean Dipole is another key driver of our weather. We can think of it as the El Nio/La Nia of the Indian Ocean. When we have both an El Nio event and a positive Indian Ocean Dipole, the drying effect can be more widespread across the continent and more pronounced.

Every time we head out into the bush for the day the one factor that we must deal with on every hike is the weather. Good or bad, the weather can make or break a hike and if we fail to pay attention to extreme weather conditions it can also present safety concerns.

So, every time we decide to go out hiking be it for a few hours or multiple weeks we need to look at what the weather conditions are doing. The length of a hike will determine what factors you need to consider and how you should proceed.

If you are hiking for a single day or less, you should be checking the short term weather forecast for the rest of the day to ensure we have the appropriate equipment/clothing for your outing. With most people having smart phones this is very easy to do or failing that the internet or local newspaper, preferably just published.

A good example here was a walk we did to the summit of Mount Kosciusko from the chairlift on Christmas day a few years ago. When we started the walk the temperature was 25 celsius but within a matter of half a day that we were out on our walk the temperature had plummeted to 4celsius. I could only watch with amazement as families with you children including one 5 year old girl wearing sandals and a lightweight dress just keep on going. The Australian Alps is well known for is highly variable and rapidly changing weather conditions, so you need to come prepared. ff782bc1db
