Early December feels peaceful in the Coachella Valley. Holiday lights go up, mornings turn cool, and many seasonal homeowners make quick trips to visit family. It’s a beautiful time of year — but also one of the most overlooked risk periods for desert homes left empty.
While early December seems mild, the combination of shifting temperatures, winter irrigation changes, increased pest activity, and slower holiday service schedules creates the perfect environment for issues to develop quietly. And because most homeowners assume December is “safe,” small problems are more likely to go unnoticed.
Here’s what makes this time — the very start of winter — more important than most people realize.
1. Sudden Temperature Drops That Stress Desert Homes
Early December brings the first real temperature swings of the season. Warm afternoons can fall into chilly nights in a matter of hours.
Your home feels these shifts more strongly when it sits empty:
- HVAC systems cycle harder
- Window and door seals expand and contract
- Condensation can form in closed rooms
- Older water heaters work overtime
According to the U.S. Department of Energy, heating and cooling systems are some of the largest energy loads in any home, and they work best when temperatures are managed consistently rather than allowed to swing dramatically between extremes.
Even a short period of imbalance can create humidity pockets, stale air, or strain on aging systems. Without regular airflow or oversight, these early-winter swings can start small problems that grow quietly through the month.

2. Winter Irrigation Schedule Changes Increase the Chance of Hidden Leaks
December is when HOAs, landscapers, and cities switch to winter watering schedules.
This transition is where problems sneak in:
- Timers reset incorrectly
- Irrigation zones shut off unexpectedly
- Broken sprinkler heads go unnoticed
- Soil changes expose plants to stress
The Coachella Valley Water District’s watering guide shows just how much recommended watering frequency and volume drop between fall and winter months — and how easily misadjusted timers can over- or under-water landscaping.
Because temperatures are cooler, leaks don’t dry out quickly. Moisture can sit longer beneath gravel, near foundations, or around planters — and homeowners often won’t see signs until returning weeks later.
If you’re planning to be away for most of December, this is a good time to review long-absence prep tips like securing irrigation, managing mail, and setting interior systems correctly:
3. Pests Begin Seeking Warmth — and Quiet Homes Become Targets
As nights get colder, pests in the desert go looking for warmth.
Empty homes offer:
- Consistent shelter
- No foot traffic
- Quiet corners
- Steady interior temperatures
Winter pest-prevention guidance consistently notes that rodents and insects begin moving indoors as outdoor temperatures drop, seeking warm, protected spaces with access to food and water.
Many homeowners don’t realize pest activity usually spikes in the late fall and early winter — not because pests “appear” all at once, but because this is when they begin searching for long-term indoor shelter. Once inside, they can settle into attics, garages, and wall voids where activity goes unnoticed for months.
A professional Home Watch visit can spot early indicators: droppings, chewed materials, or unusual noise or odor before it turns into a larger infestation.
4. Holiday Service Delays Slow Down Response Times
Even the most reliable contractors shift their schedules around early December:
- HVAC companies reduce staff
- Plumbers book out further
- Landscapers take extended weekends
- Irrigation techs limit calls
- Vendors pause non-urgent work
That means if something goes wrong while you’re away — even something small — help may not come immediately.
A simple leak, outage, or HVAC problem that would be fixed within hours in October may sit unattended for days during December. And when an issue sits, it grows.
This is one of the biggest reasons early December is risky: problems that start during this time often aren’t addressed quickly.

5. Homeowners Underestimate the Season — and That’s When Issues Happen
Many seasonal residents assume December is “safe” because:
- Temperatures feel comfortable
- Storms are rare
- Pests seem less active
- Landscaping slows down
- Holiday trips are short
But those assumptions are exactly what make early December problems so easy to miss.
A home doesn’t need extreme heat or heavy storms to develop issues.
All it needs is time, silence, and small unnoticed changes.
That’s why early December — quiet, calm, and seemingly harmless — becomes one of the most overlooked risk periods of the entire year.
Protect Your Home During the Most Overlooked Month
Early December isn’t the season of emergencies — it’s the season of subtle changes.
Temperature swings
Irrigation shifts
Pest activity
Holiday delays
Short absences
Each one is small on its own… but together, they create the perfect environment for problems to grow when no one is watching.

A simple Home Watch visit can prevent these early December surprises — ensuring your Coachella Valley home stays safe, balanced, and exactly as you left it.
Frequently Asked Questions
• Why is early December riskier than other winter months?
Because it includes the first temperature drops, major irrigation schedule changes, and the start of holiday service delays — all at once.
• Can small temperature shifts really affect a home?
Yes. Even mild swings between warm afternoons and cold nights can strain HVAC systems, window seals, and airflow in empty homes.
• Why do pests become more active in December?
As nighttime temperatures fall, pests look for warm, quiet shelter — and seasonal homes offer ideal conditions when they sit empty for days or weeks.
• What irrigation issues happen during winter transitions?
Timer resets, broken sprinkler heads, unnoticed leaks, or shut-off zones are all common during winter schedule changes and can stay hidden longer in cooler weather.
• Should I check my home even if I’m gone only a few days?
Yes. December problems often form quickly — and holiday response delays can make small issues worse by the time you return.
