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 (86 °F) arrives in the afternoon, about two hours after solar noon; the low (56 °F) 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 Pasadena 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 Pasadena the model publishes no rain probability, so the expectation column is our reading.

Understanding the weather and climate of Pasadena
Is this week in Pasadena above or below the October normal?
The average of the next 7 days in Pasadena works out at 71 °F, against a normal of 73 °F for October over 25-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2025). That is 34 °F below typical, a modest gap and well within week-to-week variation.
Within the week the highest maximum lands on Thu 22/10 (86 °F) and the lowest minimum on Sat 17/10 (56 °F). None of the 7 forecast days collects measurable rain in Pasadena.
When is the wettest and the driest month in Pasadena?
On the 25-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2025) climatology, the wettest month in Pasadena is September, at about 6.8 in, and the driest is February, at 2.8 in. The two extremes differ by only 2.5 times, which means rain is spread fairly evenly across the year in Pasadena. For October, the month you are reading this in, the average is 5.7 in.
What does the dew point say about how Pasadena feels?
Right now in Pasadena the air is at 81 °F with a dew point of 71 °F and relative humidity of 72%. That distance between temperature and dew point is the comfortable band: the body can cool itself by evaporation without effort. A dew point above 20 °C, like today’s in Pasadena, is the threshold where nearly everyone starts calling the air sticky.
What is the climate of Pasadena like through the year?
The warmest month in Pasadena is August (84 °F on average) and the coldest is January (54 °F), a swing of about 17 °C around an annual mean of 70 °F. A swing of this size means a genuinely temperate climate: summer and winter call for different clothes, different housing and different habits.
Because Pasadena lies in the northern hemisphere, at 29.69° north, summer falls in June, July and August, in the middle of the calendar.
How far is Pasadena from Houston?
The nearest large city to Pasadena is Houston, about 17 km away in a straight line, to the north-west, with 2,314,157 inhabitants. In that band the temperature of the two rarely differs by more than a degree or two, but a summer downpour can hit one and miss the other: heat showers are only a few kilometres wide. Being larger, Houston shows up in more searches, and plenty of people end up reading its forecast assuming it covers Pasadena.
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
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.
