Darwin weather by month, at a glance

The whole year in one picture — sky, rain, humidity, temperature and travel score. Click any band to jump to its full chart.

Each stripe is one measure across the whole year, stacked so a single day reads top to bottom. The sky band runs overcast grey on top down to clear blue at the base — more blue means sunnier — followed by the rainfall curve, the humidity band, a temperature strip that tints each stretch of the year by how warm its average high is, and the travel-score line at the foot. Scan straight down any date to read that day across every measure at once; the score climbs highest around late May to late August.

The felt-temperature range through the year — heat index on the day's high (summer humidity), wind chill on the night's low (winter wind). The dashed lines are the plain thermometer; the gap is how much hotter or colder it really feels.

On the hottest afternoons, once humidity is folded in, Darwin feels like about 41°C (around December 6). About 317 days a year carry some heat stress, and 93 of them tip into dangerous heat (feels-like above 39°C), peaking in December.

Average hourly temperature in Darwin

A compact picture of the whole year, hour by hour: each column is a day, each row an hour, and the color is the modeled average temperature. Darker overlays mark night, lighter ones the civil-twilight hours around sunrise and sunset.

Read left to right for the day of the year and top to bottom for the hour of the day; the color is the modeled temperature, cool blues through to hot reds on the same scale as the other charts. A vertical slice is a single day's swing — coolest just before dawn, warmest in the mid-afternoon — while a horizontal slice follows one hour across the seasons. The darker overlay marks night and the lighter one the twilight around sunrise and sunset. Colors run warmest on October afternoons, near 34°C, and coldest before dawn in February, near 26°C.

Humidity comfort

DryComfortableHumidMuggyOppressiveMiserable

Share of days at each humidity comfort level, based on the dew point — the measure that tracks how muggy it actually feels.

Humidity comfort is graded by the dew point — the temperature at which the air would be fully saturated — because it tracks how muggy it actually feels far better than relative humidity does. A low dew point feels dry and crisp; a high one feels sticky and oppressive no matter the reading on a humidity gauge.

In Darwin, how humid it feels changes dramatically over the year.

The more humid part of the year lasts 7.8 months, from around September 9 to May 3. The muggiest month is January, when the air feels humid, muggy or worse about 100% of the time.

The most comfortable stretch runs from around May 4 to September 8, and June is the most comfortable month — the air is dry or comfortable 57% of the time.

Wind

Average wind speed through the year, banded into plain-language speed zones so a number reads as 'breezy' or 'calm' without knowing the scale.

This is the average sustained wind speed at the standard 10 metres above open ground — the steady flow a weather station reports, not the sharper gusts that come and go, which can run half again as fast. It's the number that says whether a place is generally breezy or calm.

Across the year, average wind speed in Darwin is typically calm, near 10 km/h, and varies little with the seasons.

The windier part of the year lasts 2.8 months, from around Dec 18 to Mar 11. The windiest month is February, averaging about 12 km/h (light breeze).

The calmer part of the year runs from around Jul 23 to Dec 17, with November the calmest month at about 8 km/h.

Best time to visit Darwin

TravelBeach/poolTemperatureCloudsPrecipitation

To characterize how pleasant the weather is in Darwin throughout the year, we compute two travel scores — one for general sightseeing, one for beach and pool weather.

Around mid August, Darwin is still near the tail of its best-weather window — great conditions with the peak-season crowds already thinning.

Inferred from the travel-score curve; month-by-month visitor numbers are a planned addition.

The travel score favors clear, rainless days with daytime highs between 18°C and 28°C. Based on this score, the best time of year to visit Darwin for general outdoor tourist activities is from late May to late August, with a peak score in the last week of June.

UV index (midday) in Darwin by month

LowModerateHighVery highExtreme

Clear-sky midday UV index through the year, shaded by the WHO exposure levels — how much sun protection each month calls for.

Under clear skies, the midday UV index in Darwin peaks around February 20 at about 16 (extreme) — sunscreen, a hat and midday shade are essential. It bottoms out near June 18 at about 9 (very high).

The index reaches 3 or more — the level where the WHO recommends sun protection — every month of the year.

Average hourly UV index in Darwin

LowModerateHighVery highExtreme

Modeled clear-sky UV for every hour of every day — when in the day sun protection actually matters.

The whole year hour by hour: each column is a day, each row an hour, and the color is the modeled clear-sky UV index — the midday peak scaled down as the sun sits lower in the sky. Darker overlays mark night, lighter ones the civil-twilight hours around sunrise and sunset.

UV falls off far faster than brightness as the sun drops, so even in February the burn window is concentrated in the middle of the day: about 8.5 hours a day reach index 3 (protection recommended), and 7 hours reach 6 or more. Mornings and late afternoons stay comparatively gentle year round.

Growing degree days tally heat above 10°C: each day adds however many degrees its average temperature runs over that threshold, and cold days add nothing. Darwin banks about 6,468 degree days a year, and the running total — which growers use to time plantings and predict maturity — climbs fastest around November.

Solar energy

Average daily shortwave solar energy reaching the ground, banded into brightness zones so the number means something at a glance.

Solar energy is how much sunlight actually reaches the ground each day, measured in kilowatt-hours per square metre (kWh/m²) — the combined effect of how long the sun is up, how high it climbs, and how much cloud gets in the way. It's the raw fuel a solar panel has to work with: for scale, 1 kWh/m² a day is dim and wintry, while 7+ is desert-bright.

Darwin receives about 5.8 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 5.2 and 6.8 kWh/m².

The brighter stretch of the year lasts 4.3 months, from around Aug 7 to Dec 14. The brightest month is October, averaging about 6.8 kWh/m² (intense).

The dimmest month is February, down near 5.2 kWh/m² — roughly 23% less than the October peak.
