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 (96 °F) arrives in the afternoon, about two hours after solar noon; the low (65 °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 Calexico 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 Calexico the model publishes no rain probability, so the expectation column is our reading.

Understanding the weather and climate of Calexico

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

The average of the next 7 days in Calexico works out at 78 °F, against a normal of 76 °F for October over 25-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2025). That is 34 °F above typical — a small gap, the size the atmosphere wanders from one week to the next.

Within the week the highest maximum lands on Fri 16/10 (96 °F) and the lowest minimum on Thu 22/10 (65 °F). None of the 7 forecast days collects measurable rain in Calexico.

When is the wettest and the driest month in Calexico?

On the 25-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2025) climatology, the wettest month in Calexico is February, at about 0.94 in, and the driest is June, at 0.04 in. The gap is 24 times: Calexico 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 0.35 in.

What does the dew point say about how Calexico feels?

Right now in Calexico the air is at 76 °F with a dew point of 47 °F and relative humidity of 37%. 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 Calexico like through the year?

The warmest month in Calexico is July (95 °F on average) and the coldest is December (55 °F), a swing of about 22 °C around an annual mean of 74 °F. A swing above twenty degrees is continental: summer and winter are almost two climates at the same address.

Because Calexico lies in the northern hemisphere, at 32.68° north, summer falls in June, July and August, in the middle of the calendar.

How far is Calexico from Chula Vista?

The nearest large city to Calexico is Chula Vista, about 148 km away in a straight line, to the west, with 265,757 inhabitants. At that distance it is already common for Calexico and Chula Vista to have different days, because a front or a squall line takes hours to cross the gap. Being larger, Chula Vista shows up in more searches, and plenty of people end up reading its forecast assuming it covers Calexico.

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.

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.
