Sun, heat and bushfires in Sydney: a Brit's guide to staying safe

Most Brits arrive in Sydney expecting a tan. What they get, if they're careless, is sunburn by lunchtime in October and a crash course in fire danger ratings by Christmas.

The short version

• Australia has some of the highest UV levels in the world. Protect your skin whenever the UV index is 3 or above, which in Sydney is most days for much of the year [1].
• The SunSmart steps: slip on clothing, slop on SPF 50+ sunscreen, slap on a broad-brimmed hat, seek shade and slide on sunglasses [2].
• Extreme heat is a serious risk. Older people, babies, pregnant women and people with health conditions are most at risk [3][7].
• The NSW Bush Fire Danger Period runs from 1 October to 31 March, and conditions can stretch it [5].
• Learn the four fire danger ratings (Moderate, High, Extreme, Catastrophic) and have a written bushfire plan if you live near bushland [6].

The sun: why it's different here

Back home, you might reach for the factor 30 for a week in Cornwall. In Sydney you need it on the school run. Cancer Council Australia says two in three Australians will be diagnosed with skin cancer in their lifetimes [2], and British skin, built for drizzle, is no better prepared.

Reading the UV index

The Bureau of Meteorology forecasts the UV index every day and issues "sun protection times" when it's expected to reach 3 or above [1].

You'll find the UV forecast on the Bureau of Meteorology website, in many weather apps and on the free SunSmart app, which can alert you when the UV hits 3 [1]. UV isn't heat. A cool, breezy spring day in September can still have a high UV index, which is how many newcomers get burnt at their first barbie.

The five SunSmart steps

1. Slip on sun-protective clothing that covers as much skin as possible, such as long sleeves and collars [2].
2. Slop on SPF 50 or higher, broad-spectrum, water-resistant sunscreen at least 20 minutes before you go outside. Reapply every two hours, and after swimming or towelling off. An adult needs about seven teaspoons to cover the whole body [2].
3. Slap on a broad-brimmed, bucket or legionnaire hat. Caps don't cover your ears and neck [2].
4. Seek shade, remembering UV bounces off water and sand [2].
5. Slide on close-fitting, wraparound sunglasses that meet the Australian Standard [2].

Kids at Sydney schools follow a "no hat, no play" rule, so buy a proper school hat early. And book a skin check with a GP if you notice a new or changing mole. In Australia that's treated as routine, not fussing.

The beach

While we're at Bondi: the FCDO travel advice for Australia, when we checked on 7 November 2026, said that "rip currents are the main hazard for all swimmers and surfers" and that "they can happen at any beach and can sweep even the strongest swimmer out to sea" [7]. Swim between the red and yellow flags, where lifeguards patrol.

Heatwaves

Sydney summers are warm and often humid, but the real danger is the run of very hot days, especially in Western Sydney, where Penrith and Parramatta get far hotter than the coast. The FCDO advice puts it simply: "Extreme heat is a serious risk in Australia" [7].

NSW Health lists the people most at risk: older people, people with existing medical conditions, babies and young children, outdoor workers, socially isolated people, people who are homeless and pregnant women [3]. If that's you or your elderly mum visiting from Britain, plan ahead.

How to cope:

• Watch the forecast. The Bureau of Meteorology runs a heatwave service, and NSW Ambulance publishes heatwave warnings by area [3].
• Drink water regularly, before you're thirsty. NSW Health even suggests checking the colour of your wee [3].
• Keep the house cool. Close blinds and curtains on the sunny side in the morning. Many older Sydney flats have no air conditioning; a fan helps, and shopping centres, libraries and cinemas are cool places to sit out the afternoon.
• Never leave children or pets in a car, not even for a minute.
• Check on neighbours who live alone.

If you feel dizzy, sick, confused or stop sweating, get help. Call healthdirect on 1800 022 222 for free health advice at any hour, or 000 (triple zero) in an emergency [3]. It's the Australian 999, and it's worth programming into your mobile on day one.

Bushfire season

Bushfires aren't only an outback problem. The FCDO travel advice says "bushfires can occur in any part of Australia, including areas close to towns and cities", that the risk is highest "at the height of the Australian summer from November to February", and that fires "can start and change direction and become a risk to life very suddenly" [7].

Sydney is ringed by national parks. Suburbs on the edge of the Blue Mountains, the Hills District, the Northern Beaches, the Sutherland Shire and the bushy fringes of the North Shore all back onto bushland. Many lovely streets with gum trees at the bottom of the garden are, in fire terms, bush fire prone land. Ask about it before you rent or buy.

The Bush Fire Danger Period

The statutory Bush Fire Danger Period in NSW runs from 1 October to 31 March, though local conditions can move the dates [5]. During it you need a permit to burn anything in Rural Fire districts, and in Fire and Rescue NSW districts, which cover much of the city, you need a permit all year [5]. The bonfire you'd build for Bonfire Night back home is a definite no.

Fire danger ratings

The NSW Rural Fire Service sets a fire danger rating each afternoon for the next day. Forecasts are provisional, so check the official rating on the day [8]. On some days a total fire ban is declared as well [8], and lighting fires in the open is off the table.

Fire warnings

If a fire does start, warnings follow three levels: Advice, Watch and Act and Emergency Warning. An Emergency Warning means act now to survive. Follow them through the RFS's Hazards Near Me app, the RFS website and ABC local radio, which is the official emergency broadcaster. Don't wait for someone to knock on the door.

Getting your home and plans ready

If you live anywhere near bushland, make a plan before October. It takes an evening.

1. Write a bushfire survival plan with everyone in the house: when you'll leave, where you'll go and how you'll get there. The RFS has a template.
2. Decide your trigger. For most families with no firefighting experience, the safest plan is to leave early, on Extreme or Catastrophic days, before a fire starts.
3. Prepare the property. Clear gutters, cut back overhanging branches, keep grass short, move woodpiles and doormats away from the house, and keep a hose that reaches every side.
4. Pack a bag with documents, including your British and Australian passports, medicines, chargers, water and something for the pets.
5. Check your insurance. Make sure home and contents cover includes bushfire, and that the sum insured would rebuild at today's prices.
6. Tell family back home how you'll let them know you're safe. Time differences and patchy phone signal make that harder than you think.

Renters should ask the landlord or agent about gutter cleaning and fire plans for the block. Our guide to renting in Sydney covers what your lease says.

If a big fire or another crisis does hit, the FCDO's Living in Australia guide notes that you can get help from the UK government abroad, including in an emergency [4]; see our guide to consular help from the FCDO. And for local tips on which suburbs, schools and roads are affected each season, our community group for Brits in Australia is a good place to ask.
