A day card that says “Valley of the Winds, Thursday” leaves out the one rule that decides the day. Parks Australia closes that track beyond its first lookout from 11 am when the forecast or actual temperature reaches 36°C. Other walks use a different threshold and a different hour. Write the closure time on the card and count backwards from it.
The signal: named tracks, named hours, two thresholds
On 14 October 2026 we checked Parks Australia’s walk pages for Uluṟu-Kata Tjuṯa National Park. The Valley of the Winds walk at Kata Tjuṯa closes at the first lookout, Karu, from 11 am when the forecast or actual temperature reaches 36°C or above. At Uluṟu, the north-east walk closes for the day from 11 am at 40°C or above. The Lungkaṯa walk closes for the day from 2 pm, also at 40°C.
The general advice is broader. The park’s staying-safe page says to walk only in the cooler parts of the day and to avoid 2.30 pm to 6.30 pm. In summer, it strongly recommends not walking after 11 am. Carry and drink at least one litre of water per person per hour. The visitor guide adds that hot weather also happens outside the summer months.
That last line is easy to miss. On the morning of 14 October, the Bureau of Meteorology’s Yulara forecast showed 37°C for Monday 19 October and 36°C for Tuesday 20 October. Both sit at or over the Valley of the Winds threshold in mid-spring. Forecasts change, so treat those numbers as a dated example, not a prediction for your trip.
What breaks when the closure is read as a temperature
The finish line: 11 am is when the track beyond Karu Lookout closes. The full Valley of the Winds circuit is 7.4 km and takes 3–4 hours. Kata Tjuṯa is about 45 minutes’ drive from Ayers Rock Resort. “Start before 11” isn’t the plan. “Leave the resort around 6” is.
The wrong threshold: a walk at Uluṟu that stays open at 38°C doesn’t mean the Valley of the Winds does. The tracks don’t share one number, so one forecast can close one walk and leave another open.
Forecast or actual: the rule says forecast or actual temperature. A 35°C forecast doesn’t promise the track stays open if the day runs hotter.
The afternoon slot: a plan that puts the big walk after lunch because the morning was “for sunrise” has put it in the hours the park tells you to avoid, even on days with no formal closure.
Four checks before a hot-weather walk goes on the day
Treat a heat rule as a clock
Which threshold this track uses: 36°C or 40°C, and which section closes. Copy it from the walk’s own page, not from a general heat page.
When it closes and when you must finish: take the closure time, subtract the walk’s listed duration, the drive, and a buffer for parking, toilets and children. That gives your leaving time. Check it against the park’s opening hour for the month.
Which number you’re reading: the Bureau of Meteorology forecast the evening before, and the park’s alerts on the morning. The visitor guide also suggests checking the forecast at your hotel or the Cultural Centre.
What the hot-day version looks like: the short out-and-back, such as Karu Lookout instead of the full circuit, an indoor anchor such as the Cultural Centre, or a swap with a cooler day. Decide it before the morning, not at the trailhead.
The four checks are our recommendation, built from the park’s own pages. They aren’t a checklist the park publishes. Thresholds and hours can change, so reopen the walk pages the week you go.
Where Alfred fits
Alfred starts from a travelling profile. On web Lets Go, Holiday takes origin, destination, dates, a budget step and a day pace, then Plan my trip queues generation. Day pace matters here. Slow fills only an afternoon activity slot, while Moderate fills a morning and an afternoon slot. On a hot-weather route, the walk belongs in the morning. Alfred doesn’t read a park’s heat-closure rules or a weather forecast while it writes the day.
When the itinerary is ACTIVE, it can be viewed, edited and shared. You can edit an item’s title, notes and times by hand, so “Karu Lookout, finish by 11 am if 36°C forecast” can sit on the walk card itself. Hey Alfred can move an item to a new time, or swap two full days, after you confirm. A day with a flight can’t be swapped. Book opens a partner checkout. It doesn’t buy a park pass.
Practical next step
Take every outdoor walk on your plan and fill in the four checks. If the threshold, the closing hour, the leaving time or the hot-day version is blank, the walk is still a hope. Put the closing hour on the day card before the morning you go.
