Spring in Broome really signals the end of the dry season and hints at the wet months ahead. You’ll feel the days heat up, humidity jump, and those afternoon storms start to pop up as the weeks roll by.
On average, expect daytime highs in the upper 80s to low 90s Fahrenheit. Nights warm up from the mid-60s to nearly 80°F by late spring.
As temperatures climb, the air gets noticeably heavier. Humidity ramps up fast, and cloud cover starts to build.
September usually feels bright and dry, but by November, you’ll probably notice more overcast skies and the first real hints of rain. That seasonal shift really changes how comfortable it feels outside, whether you’re strolling Cable Beach or heading out to fish.
Winds keep up their steady pace but shift a bit, and the ocean gets warm enough to make a swim pretty tempting. You also get longer daylight hours, which means more time to explore before the wet season moves in.
If you know these patterns, you’ll plan your days with fewer surprises and enjoy Broome’s spring for what it is—basically a warm-up for the tropical summer just around the corner.
Overview of Broome’s Spring Climate
Spring in Broome means warmer days, rising humidity, and more clouds. You’ll notice temperatures climbing and the chance of rain ticking up, especially toward the end of spring.
Location and Climate Classification
Broome sits on the northwest coast of Western Australia, right along the Indian Ocean. Its spot near the tropics gives it a hot semi-arid climate, with clear wet and dry seasons.
Locals split the year into two main periods: the dry season (May to October) and the wet season (November to April). Spring lands right in between, acting as a bridge from dry to wet.
The ocean helps keep extreme heat in check, but humidity rises quickly once spring arrives. Winds usually blow in from the west, with sea breezes picking up during the day.
This mix of tropical latitude, ocean influence, and changing seasons makes spring in Broome feel warm, humid, and a bit more unpredictable as the months go on.
Key Climate Averages for Spring
During spring, daily highs go from about 87°F (31°C) in early September to 91°F (33°C) by late November. Overnight lows rise faster, starting near 64°F (18°C) and reaching 80°F (27°C).
Clouds start to take over. Skies are mostly clear at the start, but by late November, nearly half the days are overcast or mostly cloudy.
Rainfall barely registers in September but picks up toward the season’s end. Monthly totals climb from almost nothing to about 1.4 inches by late November.
Humidity follows a similar curve. In September, only about a quarter of days feel muggy, but by November, over 90% of days are humid.
| Climate Factor | Early Spring | Late Spring |
|---|---|---|
| High Temp | ~87°F (31°C) | ~91°F (33°C) |
| Low Temp | ~64°F (18°C) | ~80°F (27°C) |
| Rainfall | ~0.1 in | ~1.4 in |
| Muggy Days | ~27% | ~94% |
You can really see how quickly Broome shifts from dry and comfy to hot, humid, and unsettled as summer draws near.
Spring Temperature Trends
In Broome, spring means steady warming, more humidity, and longer days. You’ll spot changes in both daytime and nighttime temps, plus gradual shifts in clouds and wind that make the heat feel different.
Average High and Low Temperatures
During spring, the average high rises from about 87°F (31°C) in early September up to 91°F (33°C) by late November. Highs almost never dip below 80°F (27°C) or soar above 99°F (37°C).
Low temperatures climb more quickly. Nights start near 64°F (18°C) in September and hit about 80°F (27°C) by late November. That steady rise means evenings start to feel warmer and, honestly, a bit less comfortable as the season goes on.
Just for reference, Broome’s hottest day of the year usually lands around 93°F (34°C) in early April. The coldest day, in July, averages lows near 58°F (14°C). These swings show how spring really bridges the gap toward the wet, humid summer.
Temperature Changes Throughout Spring
The warming trend in spring isn’t dramatic, but it’s steady. You’ll notice a 5°F jump in daily highs and a much bigger 17°F jump in nightly lows. This means mornings and evenings feel stickier and more humid as November gets closer.
Clouds become more common as well. September brings lots of clear skies, but by late November, almost half the days are mostly cloudy or overcast. That extra humidity makes the heat feel even stronger.
Rain starts to show up late in the season, though it’s still modest compared to summer. By November, there’s about a 14% chance of a wet day, which just adds to the muggy feeling. By late spring, it’s starting to feel much more tropical than it did in September.
Hourly and Daily Temperature Patterns
Weather records from Broome International Airport show that spring days follow a pretty regular cycle. Temperatures climb quickly after sunrise, peak in the afternoon, and cool off slowly overnight.
In September, mornings feel comfortable around 65°F (18°C), and afternoons reach the high 80s. By November, mornings start around 80°F (27°C) and afternoons stick in the low 90s. The gap between day and night temps gets smaller.
Hourly averages show evenings stay warm well after sunset. With less difference between highs and lows, you don’t get much relief from the heat as spring moves on. This is classic Broome—tropical and a sign the wet season is almost here.
Humidity and Comfort Levels
Spring in Broome brings clear changes in moisture as the region shifts from dry to wetter months. Humidity rises steadily, making the air feel warmer and changing how comfortable it is to be outside.
Average Humidity During Spring
Relative humidity in Broome starts to climb as the dry season fades. In September, it’s usually around 40–45%, but by November, it can hit 55–60% as the wet season nears.
The increase isn’t sudden, but you’ll notice it. The air feels heavier, and evenings seem warmer than you’d expect. Daytime highs average 31–33°C (87–91°F), and the humidity makes those temps feel even hotter.
Back in July, humidity bottoms out near 33%. So, spring definitely brings a rise in moisture, though it’s not overwhelming yet. If you’re sensitive to humidity, you’ll probably feel the difference by late October.
Impact on Daily Life and Activities
Rising humidity changes how you plan your day. Doing outdoor work or exercising in the afternoon feels tougher since your body works harder to stay cool. Light clothes, lots of water, and taking breaks in the shade help a lot.
Tourism activities—beach days, camel rides, exploring parks—are still great, but mornings and evenings offer the most comfort. The ocean stays warm, with water temps near 27–28°C, which is a nice bonus when the air feels sticky.
If you’re visiting, consider that humidity makes air conditioning in hotels and rentals more important, especially later in spring. Locals often run errands earlier in the day to dodge the worst of the heat.
Precipitation Patterns in Spring
Spring in Broome marks the change from dry to wetter months. Rainfall stays limited early on, but clouds and humidity increase as summer creeps closer.
Rainfall Amounts and Frequency
Most of spring brings very little rain. September is usually the driest month, averaging less than 1 mm of rain and often none at all. By October and November, showers become a bit more likely, but totals stay low compared to the wet season.
At Broome International Airport, long-term data shows only 0–2 days with measurable rain per month in spring. So, most days are dry and sunny—pretty ideal for outdoor plans.
Humidity does start to climb by late November, and you’ll see more clouds. Even if rain is still rare, it’s a clear sign the wet season’s on its way.
Seasonal Changes in Precipitation
Spring really marks the end of Broome’s dry spell. In September, skies usually stay clear and rain is almost nonexistent. By October, you might get a quick shower, but it rarely ruins plans.
November is when you’ll notice the most change. Rainfall starts to pick up, and the odds of storms go up a bit. It’s still nothing like the downpours of January or February, but it signals the wet season is coming.
The shift is slow, so you’ll see more clouds before real rain arrives. November stands out as a month where the dry season lingers but the first hints of monsoon weather show up.
Cloud Cover and Sunshine
Spring skies in Broome change fast, from mostly clear at the start to more clouds by the end. Meanwhile, daylight hours stretch out, so you still get plenty of sun even as clouds roll in.
Trends in Cloud Cover
At the start of spring, Broome weather is usually clear, with overcast or mostly cloudy skies on about 1 in 5 days. By late November, it’s closer to half the days.
The clearest stretch usually comes in late October, when skies are clear or partly cloudy about 79% of the time. If you love bright days, October’s a good bet.
As the season moves on, humidity builds and clouds increase. The wet season’s approach becomes obvious, and you’ll probably see more gray skies in November than September.
That steady climb in cloud cover is a big part of Broome’s spring, making the change from dry to wet obvious just by looking up.
Sunshine Hours and Daylight Length
Even with more clouds, spring brings longer days. Early September offers about 11 hours and 46 minutes of daylight. By late November, you get over 13 hours.
Sunrise shifts earlier, from around 5:58 AM in early September to about 5:05 AM by late November. Sunsets move later too, from 5:43 PM to 6:13 PM.
Broome rates as one of Australia’s sunniest spots. In October and November, you can expect close to 11 hours of sunshine per day on average, making this one of the brightest times of year.
Those long, sunny days give you plenty of time outside, whether you’re exploring Cable Beach or heading inland, even as clouds start to build.
Wind Conditions in Spring
Spring in Broome comes with steady coastal breezes that shape the weather and your outdoor plans. Winds are usually predictable, but as spring turns to summer, their strength and direction can shift a bit.
Typical Wind Speeds and Directions
Data from Broome International Airport shows moderate wind speeds in spring. Average winds range from 12 to 18 km/h (7 to 11 mph), though you might get stronger gusts in the afternoons.
The main wind direction is east to southeast. These winds bring in drier air, which helps keep humidity down compared to the wet season. By late spring, afternoon sea breezes pick up as things get hotter.
Here’s a quick breakdown of spring wind directions:
- Southeast (most common)
- East-northeast (secondary)
- Occasional westerly sea breezes
This steady wind pattern makes spring a comfortable time for activities that depend on predictable breezes.
Effects on Weather and Outdoor Activities
Spring winds in Broome really shape how you spend time outside. In the mornings, the easterly flow usually keeps the skies pretty clear.
By afternoon, that sea breeze can roll in and bring a welcome, cooler change along the coast. If you’re thinking about fishing, sailing, or even kitesurfing, you’ll probably notice the steady southeast trade winds.
Mornings tend to have lighter winds, which makes calm water outings a lot easier. Once the afternoon breezes pick up, wind sports become a lot more fun—unless you’re not a fan of choppy water.
These winds do a decent job of easing the daytime heat by moving the air around. On dry days, though, they can kick up dust and carry it inland, so if you’re heading off-road or into remote spots, maybe keep that in mind.
Travelers usually find that these wind patterns mean tours and flights run pretty smoothly. Most days, you can explore Broome’s beaches and outdoor spots without worrying too much about weather getting in the way.
