The best time to visit the West MacDonnell Ranges, season by season
A year in the ranges
Twelve months of sun and seasons
Choose a month to compare sunrise, sunset and day length, then see what the Bureau of Meteorology and the tourism bodies say about it.
Sunset
Sunrise, sunset and day length are worked out for the 15th of each month in the park west of Alice Springs, on Northern Territory time with no daylight saving. Temperatures come from the Bureau of Meteorology station at Alice Springs Airport, where day trips start; no weather station lies in the gorges.
The best time to visit the West MacDonnell Ranges is April to September for walking, but summer has its own case: warm air, empty tracks and very cold water.

- Most popularThe cooler months of April to September, Tourism NT says.1
- Hottest monthJanuary: a mean maximum of 36.6°C at Alice Springs Airport.2
- Coldest nightsJuly: a mean minimum of 3.9°C, with frost possible.3,4
- Summer upsideCheaper stays, fewer crowds and swimming weather.5
- Heat ruleSome tracks close above 36 degrees Celsius.6
The short answer: April to September, with caveats
Tourism NT puts the most popular time to visit in the cooler months of April to September, and notes that the West Macs are open year-round.1 Those months bring the walking weather most visitors picture: clear skies, warm afternoons and cold nights. Tourism Central Australia describes winter as the peak season, when accommodation, car hire and tours book out quickly.7
So the best time to visit the West MacDonnell Ranges depends on what you want. For long walks, the Pound circuit at Ormiston or a summit, pick the cool months. For swimming, warm air and fewer people, the hot months have a real case, as long as you plan around the heat. Autumn and spring are the compromise, warm by day and cooler at night.8
One caution about the figures that follow. There is no weather station inside the gorges, so every average quoted here is a Bureau of Meteorology reading from its Alice Springs Airport station, number 015590, at 546 m.9 That is the town where the day trips start; the gorges lie 18 to 156 km further west, among the ranges.10,11

West MacDonnell Ranges weather, month by month
Treat the Alice Springs figures as a sketch of how the year runs. The mean maximum climbs from 19.9°C in July to 36.6°C in January, and the mean minimum falls from 21.6°C in January to 3.9°C in July.2,3 Those two lines tell you most of what you need: hot days and warm nights in summer, mild days and near-freezing nights in winter.
The extremes are what catch people out. The airport averages 21.8 days of 35°C or more in January alone, and 93.2 such days across the year.14 At the cold end it averages 6.1 days at 0°C or below in July and 12.8 in a year.15 Tourism Central Australia also notes that summer temperatures regularly pass 40°C and can exceed 45°C.12
Sunshine is the constant. The station logs a mean of 9.6 hours of sunshine a day across the year, from 8.4 hours in June to 10.2 in January.16 Tourism Central Australia calls the region semi-arid, with roughly nine hours of sunshine a day and short, sunny winters with frosty mornings.17 Whatever month you choose, the sky will most likely be blue.
Summer: heat, closures and the best swimming
Summer is hard, but it is not closed. Tourism Central Australia lists cheaper accommodation, fewer crowds and perfect swimming weather among its benefits.5 Tourism NT frames its summer road trip from September to March, when the waterholes are full.21 Ellery Creek Big Hole and Ormiston Gorge keep their swimming holes open all year, with water that stays surprisingly cold.22
The heat sets the rules. Some tracks shut on days forecast to pass 36 degrees Celsius, so official advice is to set off at first light and be done by noon.6 In December the sun rises at around 5.40am, which makes an early start easy.23 When walking, each person should carry no less than two-and-a-half litres, and about one litre an hour is the guide in the heat.24,25
Summer also brings most of the Red Centre's rain, by Tourism Central Australia's account, along with a risk of flash flooding, though the true wet season belongs to the tropical Top End.12 At Alice Springs Airport the wettest months are January and February, with means of 41.8 mm and 42.4 mm.26 Flooding in the West MacDonnell Ranges is rare but real: check the roads before leaving, and keep off any flooded causeway whose depth and flow you cannot judge.27

Summer brings fewer crowds and swimming weather, but tracks may close above 36 degrees Celsius.5,6
If I am camping
April to September
Tourism NT rates these the best camping months, with cold nights.19
If I want wildflowers
Spring, after rain
Wildflowers bloom when spring rain falls.13
If I want a ranger walk

The Ormiston ranger station runs guided walks in those months.20
Winter: frosty nights and the busy season
Winter days are the most comfortable time of year for walking, with a mean maximum of 20.0°C in June and 19.9°C in July at the airport.2 The nights are the challenge. Tourism Central Australia warns of nights at 0°C or lower, and Tourism NT adds that winter often brings freezing temperatures, frost included.29,4
That matters most if you camp. For camping, Tourism NT names April to September as the pick of the year, with a caution that the desert can fall below zero after dark.19 A swim is still possible in winter, but the water in the gorges is cold all year, and at Redbank Gorge it is described as extremely cold.32
Winter is also the busy season. Accommodation, car hire and tours book out quickly, so book ahead.7 Campgrounds feel it too, Ormiston's above all, so turn up early in the day.33 Rangers at Ormiston Gorge lead walks and give talks from April to October, which is a reason in itself to visit in the cooler half of the year.20
West MacDonnell Ranges temperature in the water
People often ask about the West MacDonnell Ranges temperature in the water rather than the air, and the answer is cold in every season. Tourism NT warns that even in peak heat the Ellery Creek water bites with cold.34 At Redbank Gorge it recommends a pool noodle, lilo or other flotation device because the water is so cold.32
The permanent waterholes are the reliable ones. Tourism Central Australia explains that permanent holes keep water regardless of rainfall, while semi-permanent ones are best after rain.35 The park's larger permanent waterholes are Glen Helen Gorge, Redbank Gorge, Ormiston Gorge and Ellery Creek Big Hole.36 Ormiston's waterhole is estimated to reach 14 m deep at its southern end.37
Safety does not change with the season. There are no lifeguards at Central Australian waterholes, so never dive or jump in, and remember that a waterhole can get very deep very quickly.38 There are no crocodiles in the ranges, which is the one worry you can leave behind.39 In the cold months, keep your swim short and dry off in the sun.

Spring and autumn: the in-between months
Autumn, March to May, brings relief after summer, and the light on the quartzite softens as the sun sits lower. Tourism Central Australia says temperatures are still regularly in the 30s by day but cool down at night, and that autumn or spring are the best time to beat the crowds.8 At the airport, the mean maximum drops from 32.8°C in March to 23.1°C in May.2
Spring is the season of change. After a dry winter the rain is unpredictable, but when it falls the wildflowers begin to bloom.13 The mean maximum rises from 22.9°C in August to 31.3°C in October, and days of 35°C or more start to return, with 8.4 on average in October.2,14 October is also when the rain days begin to climb again, from 1.5 in September to 2.8.18
Flies arrive with the warmth. For summer walking, Tourism Central Australia suggests long socks, a flynet and a compact first-aid kit that includes a snake bandage.28 In spring and autumn a flynet is worth packing too: it weighs nothing and saves a long walk from turning into a battle. Add insect repellent for the dawn and dusk hours by the water, when the small biters are at their busiest.
Matching the season to a day trip
The day trip this site books runs year-round on the listing and takes 9 hours, between a 7:45am pickup and an evening return near 5:30 pm. Its swim at Ellery Creek Big Hole is optional and pitched at the warmer months. In winter, expect the walks to be pleasant and the swim to be brief; in summer, expect the opposite.
Book with the season in mind. Free cancellation runs up to 24 hours before for a full refund, and you can reserve now and pay later. If the forecast for your date shows extreme heat, that window gives you room to move the day. Bring a hat, sunscreen, walking shoes and swimming gear whatever the month.31
Our view: come between April and September if walking is the point, and in the hot months if you want quiet tracks and a long, cold swim. Either way, the daylight tool above lists sunrise and sunset month by month, so you can fit the coolest hours of your day around the light, and still be at Ellery Creek for a swim when the afternoon is at its warmest.
