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. 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.

How to read this page
How to read the min and the max
The week’s high (17 °C) arrives in the afternoon, about two hours after solar noon; the low (9 °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 Brighton forecast comes from MET Norway, a partir do ECMWF HRES e, na área nórdica, do MEPS, run of 16/10/2026, 01:18 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 Brighton the model publishes no rain probability, so the expectation column is our reading.

Understanding the weather and climate of Brighton
Is this week in Brighton above or below the October normal?
The average of the next 7 days in Brighton works out at 12 °C, against a normal of 12 °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 Fri 16/10 (17 °C) and the lowest minimum on Sat 17/10 (9 °C). Forecast rain adds up to 24 mm, roughly 29% of everything Brighton gets in an average October (82 mm). The wettest day is Tue 20/10, with 9.3 mm.
When is the wettest and the driest month in Brighton?
On the 25-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2025) climatology, the wettest month in Brighton is November, at about 86 mm, and the driest is April, at 43 mm. The two extremes differ by only 2 times, which means rain is spread fairly evenly across the year in Brighton. For October, the month you are reading this in, the average is 82 mm.
What does the dew point say about how Brighton feels?
Right now in Brighton the air is at 17 °C with a dew point of 15 °C and relative humidity of 90%. The two sit within a few tenths of each other: the air is all but saturated, which favours fog, dew on the car and laundry that will not dry.
What is the climate of Brighton like through the year?
The warmest month in Brighton is August (17 °C on average) and the coldest is February (5 °C), a swing of about 12 °C around an annual mean of 11 °C. A swing of this size means a genuinely temperate climate: summer and winter call for different clothes, different housing and different habits.
Because Brighton lies in the northern hemisphere, at 50.83° north, summer falls in June, July and August, in the middle of the calendar.
How far is Brighton from Portsmouth?
The nearest large city to Brighton is Portsmouth, about 67 km away in a straight line, to the west, with 208,100 inhabitants. At that distance it is already common for Brighton and Portsmouth to have different days, because a front or a squall line takes hours to cross the gap. In this pair Brighton is the larger of the two.
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.
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.
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
Relative humidity
How much water vapour the air holds compared with the most it could hold at that temperature, as a percentage. Because that ceiling rises with heat, the same amount of vapour reads high at dawn and low in the afternoon.
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.
Standard definition by MET Norway (Meteorologisk institutt) · Forecast model
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.
