Is it too late to blow out my sprinklers in El Paso, TX?

Past November 2, El Paso, TX is into the window where a hard freeze can arrive at any time, so do it now rather than waiting for a better weekend — but if a hard freeze has already been through, do not pressurise the system to check it. Drain what you can, leave it off for the winter, and inspect for damage at spring startup instead.

When is the first frost in El Paso, TX?

The long-term normal for the first 32°F freeze in El Paso, TX is around November 14, with a normal early year arriving by November 2. A light frost will not usually reach buried pipe — it is a sustained hard freeze, several hours below about 28°F, that does — but an exposed backflow preventer is vulnerable well before that. For calendar context, that median ranks 53rd of the 63 metros we publish dates for.

What does it cost to winterize a sprinkler system in El Paso, TX?

A professional blow-out in El Paso, TX typically runs $50–250 depending on zone count. Freeze repairs typically run $170–$2,500+, with the backflow preventer the priciest common casualty. If you are doing it yourself, stay at or below 50 PSI.

When can I turn the sprinklers back on in El Paso, TX?

The last spring freeze in El Paso, TX normally passes around March 17, but that is a median — half of years freeze later than it. Give it a couple of weeks of margin and treat March 29 as the earliest safe date, later if the forecast is still marginal. Re-pressurise slowly, a quarter turn at a time. All told, the system sits out roughly 18 weeks of the year here.

Sprinkler winterization dates

When to Winterize Sprinklers in El Paso, TX

Winterizing is a deadline problem, and the deadline is local. In El Paso, TX the first freeze of the autumn normally arrives around November 14, which puts the blow-out window at roughly October 17 – November 2 — start about four weeks out and be finished by November 2. El Paso, TX's deadline is not the average date, it is the early edge of it: a normal early year freezes by November 2, and the backflow preventer sitting above ground outside your house in El Paso, TX is damaged by the first real freeze rather than the tenth.

Winterize between: October 17 – November 2
Average first freeze: November 14; An early year: November 2
Turn it back on after: March 29; Median last freeze March 17, plus a margin — half of years freeze later than the median.

This is the long-term NOAA normal for the nearest first-order station, so it describes a typical year rather than this one. Elevation, cold-air drainage and how built-up your street is all move the real date at your address — watch the forecast as the window opens, and act on the first hard freeze in it rather than on the date.

The window against the freeze band

Blow-out window — October 17 – November 2
First-freeze band — from November 2
Median first freeze — November 14

Drawn from El Paso, TX's own NOAA freeze normals. The green window ends where the amber band begins: November 2 is the early edge of a normal freeze year, which is the date to be finished by.

Why October 17 – November 2, and not later

A median is not a deadline

Half of El Paso, TX's years freeze earlier than November 14, and a normal early year gets there by November 2. Scheduling the work to finish on the average date means missing it every other year.

The backflow device goes first

Buried pipe has soil buying it time. The backflow preventer is brass, above ground and full, so around El Paso, TX it can be damaged by the first real freeze rather than the tenth — and it is the most expensive part on the system.

Contractors book out

If you are hiring it out, the few weeks before the first freeze are the busiest of the irrigation year in El Paso, TX. Booking at the start of the window rather than the end is the difference between a date you chose and one you were given.

How El Paso, TX compares

Of the 63 metros we publish winterization dates for, El Paso holds the 53rd-earliest median first freeze — 52 typically freeze sooner, 9 hold out longer, and El Paso lands 20 days behind the middle of that list. Little Rock, AR lands on the very same median as El Paso — a coincidence of climate, not shared data; each metro is measured at its own NOAA station. The closest published dates on either side of El Paso belong to Jackson, MS (November 12) and Little Rock, AR (November 14) — winterization advice written for either transfers here almost unchanged, which is not true of a national average.

Between the median first freeze (November 14) and the median last spring freeze (March 17), El Paso's freeze season runs about 123 days — call it 18 weeks with the system down, under five months — a comparatively short winter. That arithmetic is behind both ends of this page: the blow-out window is the fall edge of it, and the spring-startup date is the other, pushed past El Paso's median because half of years freeze later still — leaving roughly 242 days of running season between startup and the next blow-out.

Within Texas, Austin typically freezes 2 days later (November 16); Dallas typically freezes 11 days later (November 25). El Paso is the first of the state's tracked metros to close, so its date is the safe one to borrow if you are between stations. The statewide page, by design, follows the earliest of them rather than the average.
