Our own chart, drawn from the 7-day forecast for Penzance shown above.

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 (15 °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 Penzance forecast comes from MET Norway, a partir do ECMWF HRES e, na área nórdica, do MEPS, run of 16/10/2026, 05:21 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 Penzance the model publishes no rain probability, so the expectation column is our reading.

Understanding the weather and climate of Penzance

Is this week in Penzance above or below the October normal?

The average of the next 7 days in Penzance works out at 12 °C, against a normal of 14 °C for October over 25-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2025). That is 2 °C below typical, a modest gap and well within week-to-week variation.

Within the week the highest maximum lands on Thu 22/10 (15 °C) and the lowest minimum on Sun 18/10 (9 °C). Forecast rain adds up to 23 mm, roughly 22% of everything Penzance gets in an average October (105 mm). The wettest day is Wed 21/10, with 9.9 mm.

When is the wettest and the driest month in Penzance?

On the 25-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2025) climatology, the wettest month in Penzance is November, at about 116 mm, and the driest is May, at 62 mm. The two extremes differ by only 1.9 times, which means rain is spread fairly evenly across the year in Penzance. For October, the month you are reading this in, the average is 105 mm.

What does the dew point say about how Penzance feels?

Right now in Penzance the air is at 14 °C with a dew point of 8 °C and relative humidity of 68%. That distance between temperature and dew point is the comfortable band: the body can cool itself by evaporation without effort.

What is the climate of Penzance like through the year?

The warmest month in Penzance is August (17 °C on average) and the coldest is February (9 °C), a swing of about 8 °C around an annual mean of 12 °C. With a swing that size the seasons show up in the wardrobe, but none of them is severe.

Because Penzance lies in the northern hemisphere, at 50.12° north, summer falls in June, July and August, in the middle of the calendar.

How far is Penzance from Plymouth?

The nearest large city to Penzance is Plymouth, about 103 km away in a straight line, to the east, with 260,203 inhabitants. At that distance it is already common for Penzance and Plymouth to have different days, because a front or a squall line takes hours to cross the gap. Being larger, Plymouth shows up in more searches, and plenty of people end up reading its forecast assuming it covers Penzance.

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

Beaufort scale

A 0-to-12 scale that describes wind strength by what it visibly does: smoke rising straight up at 0, leaves moving at 3, large branches bending at 6, roof damage at 9, devastation at 12. It began at sea in the nineteenth century and now has an official equivalence in metres per second.

Standard definition by World Meteorological Organization (WMO) · Beaufort scale

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.

Standard definition by MET Norway (Meteorologisk institutt) · Model run

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.
