Flood zone: it depends on the exact parcel
There is no such thing as a flood zone for a whole city. Two houses on the same street can sit in different zones, and it is the single fact here that changes most over a short distance. So this page does not guess one.
Earthquake hazard very-high
Design category D
Very high seismic hazard — at or near a major active fault. Very strong ground shaking is likely and the most stringent seismic-design provisions apply. A site-specific ground-motion study is typically required. The ASCE 7 Seismic Design Category here is D. (Short-period design value Ss ≈ 1.629 g — the standard headline measure of ground-shaking hazard.)
USGS Seismic Design Web Services (ASCE 7), assuming Site Class D — stiff or unknown soil. Real soil conditions can move the category either way.

This station records temperature and precipitation but not snowfall, so no snow column is shown. That is missing data, not a report of zero snow — Temecula may well get plenty.

Growing season zone 9b
365 frost-free days
Last spring frost around n/a, first fall frost around n/a. Roughly half of years see frost outside that window.

What this page does not tell you
- Nothing about a specific property — only the area around it.
- No flood zone, deliberately: that is parcel-level and this page would have to guess.
- Nothing about wildfire, radon, subsidence, soil or the building itself.
- Climate normals describe a typical year, not the year you are about to have.
