Visiting Jervis Bay in Autumn (March to May)
Autumn: Jervis Bay’s Golden Season
If you want the warmth of summer without the crowds, autumn is your season. March through May brings some of the most pleasant conditions of the year to Jervis Bay — warm ocean water that’s been heating up all summer, softer light that photographers love, and a noticeable drop in visitor numbers once the school holidays end.
The bush takes on warmer tones. Mornings are crisp but comfortable. Evenings cool down enough to enjoy a fire pit at your campsite or a glass of wine on the deck without sweating. And the water? March and April deliver the warmest ocean temperatures of the entire year, often hitting 23-24°C.
Autumn is Jervis Bay with the volume turned down and the colour dial turned up.
Weather: What to Expect Month by Month
March
March is summer’s encore. The heat mellows but doesn’t disappear, and the water is at its absolute warmest. This is arguably the single best month for swimming and snorkelling in Jervis Bay.
- Average high: 25-27°C
- Average low: 17-19°C
- Rainfall: Moderate (around 90-110mm, often in short bursts)
- Water temperature: 23-24°C — the warmest you’ll find all year
- Daylight: Still generous, with sunset around 7pm early in the month, shifting to 6pm as daylight saving ends
The first two weeks of March can still feel like peak season if they overlap with school holidays. After mid-March, the crowds thin dramatically. Midweek visits from late March onward feel almost private on some beaches.
The risk this month is east coast lows — intense low-pressure systems that can bring heavy rain and rough seas for a few days. They’re not common, but March is within the window. Check the forecast before you go, but don’t let the possibility scare you off. Most March days are beautiful.
April
April is when autumn properly settles in. The air cools enough for comfortable bushwalking, the ocean is still swimmable without a wetsuit, and the light turns golden.
- Average high: 22-24°C
- Average low: 14-16°C
- Rainfall: Lower than March (around 70-90mm)
- Water temperature: 21-23°C — still comfortable for most swimmers
- Daylight: Shortening noticeably, with sunset around 5:30pm by month’s end
April school holidays (usually the last two weeks) bring a bump in visitors, but nothing like the summer crush. You’ll find accommodation available at reasonable rates, though the best spots still book out for Easter and school holiday weekends.
This is an excellent month for bushwalking. The cooler temperatures make the longer trails — White Sands Walk, the Scribbly Gum Track through Booderee — genuinely enjoyable rather than the endurance test they can be in summer heat.
May
May is the transition to winter, and opinions divide. Some visitors love the quiet and the dramatic skies. Others find it too cool for a beach holiday. The reality: May is perfect if you set your expectations right.
- Average high: 19-21°C
- Average low: 10-12°C
- Rainfall: Moderate (around 70-80mm)
- Water temperature: 19-21°C — brisk but swimmable for the committed
- Daylight: Short days, with sunset around 5pm
Swimming becomes a choice rather than a given. You’ll want a wetsuit for anything beyond a quick dip. But the upside is significant: accommodation prices drop, beaches are often deserted, and the humpback whale migration begins in late May, with early sightings from the headlands.
May is a photographer’s dream. Low-angle light, dramatic cloud formations, and moody seas create the kind of shots that summer’s harsh midday sun simply can’t match. If you’re into photography, this is your month.
What to Pack for an Autumn Visit
Autumn in Jervis Bay calls for versatility. Mornings and evenings can be genuinely cool by May, while midday in March can still feel summery.
- Layers: t-shirts plus a fleece or light jacket
- Swimmers and a rash vest (you’ll still be in the water in March and April)
- A light wetsuit or spring suit if visiting in May and you plan to swim
- Walking shoes for the bush tracks — trails can be damp after rain
- Sunscreen and hat — the UV is lower but still significant
- A rain jacket — autumn showers blow through quickly but can be heavy
- Long pants and a warm jumper for evenings, especially from mid-April
Best Things to Do in Autumn
Swimming and Snorkelling (March-April)
The ocean is at peak temperature in March. Conditions for snorkelling and diving are often exceptional — warm water, good visibility, and marine life that’s been active all summer. The sheltered waters inside the bay stay calm most days, making it ideal for snorkelling at Hyams Beach, Greenfield Beach, and the rocky reefs around Plantation Point.
By mid-April, the water starts to cool but remains comfortable for swimming. Even nervous swimmers will find March and early April water temperatures inviting.
Bushwalking and Hiking
Autumn is the best season for walking. The cooler air makes longer hikes comfortable, the mosquitoes are less aggressive than in summer, and the bush has a different character — warmer colours, softer light filtering through the canopy, and fewer people on the trails.
Top autumn walks include:
- White Sands Walk (Booderee National Park) — a longer loop that takes you through forest and along coastal cliffs. Much more enjoyable without summer heat.
- Scribbly Gum Track — a gentle, shaded walk through spotted gum forest. Excellent for birdwatching in the cooler months.
- St Georges Head — dramatic clifftop views and a good chance of spotting whales from late May.
- Hyams Beach to Greenfield Beach — a coastal walk connecting two of the bay’s best beaches. Early morning in autumn is magical.

Fishing
Autumn is peak fishing season around Jervis Bay. The water temperature is ideal for a wide variety of species, and the summer crowds have thinned out, leaving more room on the popular rock platforms and wharves.
Flathead, bream, and whiting are active in the bay. Kingfish and bonito run along the headlands. Squid are abundant in the seagrass beds through March and April — Huskisson Wharf at dusk is a popular spot for squid jigging.
Kayaking and Paddleboarding
Calm autumn mornings are perfect for paddling. The bay is often glassy before mid-morning, and the resident dolphins are active year-round. Currambene Creek is sheltered from any breeze and makes an ideal autumn paddle.
Whale Watching (Late May)
The first humpback whales of the season begin their northward migration in late May. Numbers build through June and July, but keen spotters can catch early sightings from Point Perpendicular, Cape St George, and other headland lookouts from late May.
Where to Eat in Autumn
One advantage of visiting outside peak season: you can actually get a table. Summer queues at the popular Huskisson restaurants disappear, and several venues shift to cosier autumn menus featuring local oysters, hearty mains, and seasonal produce.
Check our dining guide for restaurant recommendations. Many of the bay’s best dining spots are open year-round, though some reduce their hours in the quieter months (typically closing one or two days midweek). A quick phone call to confirm opening hours saves disappointment.
The Jervis Bay oyster trail is excellent in autumn. Cooler water temperatures are ideal for oysters, and you can visit the farm doors without the summer crowds.
Accommodation in Autumn
Pricing
Accommodation prices drop after the summer school holidays end in late January, and autumn sits in the shoulder season bracket. Expect to pay 20 to 40 per cent less than peak summer rates, with the exception of Easter and April school holiday weeks.
May is the cheapest month, with some properties offering winter rates from early May. Midweek stays in May can be genuinely affordable, even at properties that charge premium summer rates.
What to Book
Self-contained holiday rentals come into their own in autumn. You’ll use the kitchen more on cooler evenings, and having a living room with a heater makes a huge difference by May. Many rental houses have fireplaces, outdoor fire pits, or wood-burning stoves — autumn luxury that’s wasted in summer.
Camping is excellent in March and April. Cool nights make sleeping in a tent comfortable rather than the sweaty ordeal it can be in January. Booderee National Park campgrounds are easier to book outside of school holidays. Bristol Point and Green Patch are both superb in autumn — fewer neighbours, more wildlife visiting camp at dusk.
By May, camping becomes a cold-weather activity. Not everyone’s cup of tea, but if you have good gear and enjoy crisp mornings, the campgrounds are beautifully quiet.

Autumn Events and Activities
ANZAC Day (25 April)
Huskisson holds a dawn service at the war memorial, followed by a march and community gathering. It’s a moving local event and worth attending if you’re in the area. The RSL club opens early for traditional ANZAC Day activities.
Easter Weekend
Easter is the biggest autumn event on the calendar. The area fills up — not to summer levels, but noticeably busier than a regular autumn weekend. The Huskisson markets operate on Easter Saturday, and local cafes and restaurants run special menus.
Book accommodation well in advance for Easter. Campground sites at Booderee go quickly.
School Holidays (Late April)
The two-week autumn school holidays bring families back to the bay. It’s busier than regular autumn weekdays but manageable. Activities like dolphin cruises and kayak tours run more frequently during school holidays.
Is Autumn the Best Time to Visit?
Every season at Jervis Bay has its strengths. But autumn offers a combination that’s hard to beat: warm water (at least in March and April), comfortable air temperatures, beautiful light, reduced crowds, and lower accommodation prices.
If you’re flexible on dates, aim for late March through mid-April. You’ll get warm enough water for swimming, cool enough air for walking, and you’ll miss both the summer rush and the school holiday bump.
May suits those who don’t need beach weather and prefer the bay at its quietest. Add a wetsuit and a warm jacket and May reveals a different, moodier side of Jervis Bay that’s deeply appealing.
Whatever month you choose, autumn rarely disappoints.
