This column is our own reading: the global model does not publish a probability of precipitation for this region, so we classify the day from the forecast symbol and the total in millimetres. It is not an official probability figure.

What each number means

Rain (mm): 1 millimetre of rain is 1 litre of water per square metre. Up to 2 mm in a day is drizzle; from 10 mm it is proper rain; more than 50 mm in a few hours is the amount that floods streets.
Humidity: Relative humidity is how much water vapour the air holds compared with the most it can hold at that temperature. Above 80% sweat evaporates slowly and heat feels worse; below 30% your throat and eyes dry out.
Dew point: The dew point is the temperature at which the air would start to condense. The closer it is to the air temperature, the muggier it feels. Above 20 °C the air already feels heavy.
Feels like: "Feels like" combines temperature, wind and humidity: strong wind carries heat away from the body, so it feels colder than the thermometer; high humidity in the heat makes it feel warmer.
Wind: Wind is given as a speed and the direction it blows from. Up to 20 km/h you barely notice it; at 40 km/h it moves branches and parasols; above 60 km/h it brings down trees and roof tiles.
Cloud cover: Cloud cover as a percentage is how much of the sky is covered. Up to 20% is a clear sky; above 80% the sun barely gets through.
Chance of rain: The model does not publish a probability of precipitation for this region.

It is not an official probability figure.

How to read this page

How to read the min and the max

The week’s high (37 °C) arrives in the afternoon, about two hours after solar noon; the low (20 °C) just before sunrise. Both are air temperature in the shade, two metres above ground — in direct sun or over asphalt a thermometer reads higher.

Where this number comes from

The Mount Isa forecast comes from MET Norway, a partir do ECMWF HRES e, na área nórdica, do MEPS, run of 16/10/2026, 01:17 UTC. The month-by-month climate comes from NASA POWER, climatology of 25-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2025). Both are credited in full at the foot of this page.

What a forecast cannot promise

Out to two days accuracy is high; by day seven the trend matters more than the exact figure. For Mount Isa the model publishes no rain probability, so the expectation column is our reading.

Understanding the weather and climate of Mount Isa

Is this week in Mount Isa above or below the October normal?

The average of the next 7 days in Mount Isa works out at 28 °C, against a normal of 28 °C for October over 25-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2025). The gap is under one degree, so the week sits squarely inside what the season normally brings.

Within the week the highest maximum lands on Thu 22/10 (37 °C) and the lowest minimum on Sun 18/10 (20 °C). Forecast rain adds up to 6.4 mm, roughly 49% of everything Mount Isa gets in an average October (13 mm). The wettest day is Fri 23/10, with 4.1 mm.

When is the wettest and the driest month in Mount Isa?

On the 25-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2025) climatology, the wettest month in Mount Isa is January, at about 144 mm, and the driest is July, at 3.0 mm. The gap is 48 times: Mount Isa has a clearly separated wet season and dry season, so planning building work, travel or planting around the calendar genuinely pays. For October, the month you are reading this in, the average is 13 mm.

What does the dew point say about how Mount Isa feels?

Right now in Mount Isa the air is at 34 °C with a dew point of 16 °C and relative humidity of 35%. The two are far apart, the signature of dry air: heat feels milder than the reading, but throat, eyes and skin dry out fast.

What is the climate of Mount Isa like through the year?

The warmest month in Mount Isa is December (31 °C on average) and the coldest is July (17 °C), a swing of about 14 °C around an annual mean of 25 °C. A swing of this size means a genuinely temperate climate: summer and winter call for different clothes, different housing and different habits.

Because Mount Isa lies in the southern hemisphere, at 20.73° south, summer falls in December, January and February — which is why the warmest month shows up at either end of the calendar.

How far is Mount Isa from Townsville?

The nearest large city to Mount Isa is Townsville, about 781 km away in a straight line, to the east, with 201,313 inhabitants. With more than two hundred kilometres between them, using the Townsville forecast for Mount Isa is a common mistake: these are weather regimes that can diverge for days. Being larger, Townsville shows up in more searches, and plenty of people end up reading its forecast assuming it covers Mount Isa.

Words on this page

Apparent temperature

The temperature the body actually feels, rather than the one on the thermometer. It combines air temperature with wind, which carries heat away faster, and humidity, which slows the evaporation of sweat. That is why 30 °C in dry air with a breeze is easier than 28 °C in still, muggy air.

Apparent temperature

Dew point

The temperature air would have to cool to, at constant pressure and moisture, for water to start condensing. The closer the dew point sits to the air temperature, the less room the vapour has and the muggier the day feels.

Dew point

Millimetre of rain

The depth of water rain would leave on a flat surface with no run-off. One millimetre is one litre per square metre, no matter how large the area measured is.

Standard definition by World Meteorological Organization (WMO) · Millimetre of rain

Climate normal

The average of a climate element — temperature, rainfall, humidity — computed over a long, standardised period, usually thirty years. It does not predict anything: it says what is typical for that place in that month, and gives you a ruler for calling a week warm or wet.

Standard definition by World Meteorological Organization (WMO) · Climate normal

Forecast model

A program that solves the equations of the atmosphere on a grid of points and steps forward in time from the state observed now. Your city forecast is the model value at the nearest grid point, which is why two neighbouring towns get almost the same numbers.

Model run

The time the model was executed with the latest observations. Every forecast belongs to a run, and runs age: one from six hours ago knows nothing about the shower that started afterwards. It is the first thing to check when two sources disagree.
