Recalculated weekly. New drought data lands every Thursday — check back Friday for next week's score.
Measured from 80% of the signals — HVAC not published for this area.
The Home Stress Index measures conditions in an area, not damage to a home. It is not a prediction, an inspection, or a probability of loss.
78670 is in Guadalupe County. The readings shown are for Bexar County, which is the county we publish for the San Antonio metro — so they describe nearby conditions rather than Guadalupe County itself.
Five signals, five quick checks
Each signal scores conditions around 78670 on a 0–100 scale, shows exactly what's driving it, and gives you one specific thing to check on your own house — most take under two minutes from the ground. Never a prediction of damage to a specific house. How scoring works ↗
Roof & Storm
48/100Moderate
Recency-weighted storm activity, 26 weeks
Strong wind gusts were recorded in the county.
Why this reading →
Severe-thunderstorm wind gusts were recorded in the county. Some recorded events carry no measured magnitude; those are counted at the lowest severity rather than assumed severe.
28.08 Wind gusts under 58 mph — 7 events, recency-weighted
This week's check: Walk the perimeter and look at gutters and downspouts for dents.

Foundation & Soil
43/100Moderate
Weekly drought severity, 52 weeks
In 39 of the last 52 weeks, part of the county was in severe drought or worse.
Why this reading →
The score reflects how much of the county was affected each week, not just the worst category recorded. Derived from drought persistence alone. We hold no soil-composition or per-home data, so this describes the moisture conditions around houses in the county, not any one foundation.
42.52 Mean drought severity over 52 weeks — Each week scored by its D-level, scaled by the share of the county at that level
32% of the county is currently at D1; the rest is less dry.
Why this reading →
Reads the same U.S. Drought Monitor feed as Foundation & Soil, but the current week rather than the trailing year. The two are related readings, not independent evidence.

HVAC
—Not published for this area
No National Weather Service forecast feed for San Antonio.
Why this reading →
Heat load is most of this signal, and air quality alone would understate cooling demand badly enough to mislead, so no HVAC score is published for this area.

Small moves are normal. What matters is the trend — a signal that climbs for three or four straight weeks is your early warning. Want us to watch it for you? A free account emails you when a signal for your county moves meaningfully. Get weekly change alerts →
This is a recomputation, not a stored history: we compare today’s reading with what the same method would have produced a week ago from the same records.
How 78670 compares
Modeled — per-ZIP coming soon
Every input behind this score is recorded at county or metro level, so every ZIP in the metro currently resolves to the same reading. A ZIP-vs-metro comparison would be modelled, not measured, so we do not publish one yet.
We won't publish a ZIP-vs-ZIP comparison until it's measured rather than modeled — when it is, your dashboard will have it first. Get notified when per-ZIP scores launch → (free account)

The score above is about your area. Let's make it about your house.
Conditions are only half the story — the other half is what they're landing on. A free account starts keeping track of your side of it:
Alerts when it matters, quiet when it doesn't. Freeze, hail, extreme heat and flooding recorded for your county, each with what to check. You choose which ones you get.
Maintenance that runs itself. Filters, gutters, pest treatment, alarm tests. Mark one done and the next due date recalculates from that day. No spreadsheet, no sticky notes.
Your paper trail. The checks you log and the conditions we record become a dated history of your home — useful for an insurance claim, and for the day you sell.
Your ZIP and home saved — so the reading you want is the one you land on.
No password — we email you a sign-in link. No credit card, no phone number, and we never sell your data. Area readings stay county-level; an account personalises what you track, not the precision of the data.
