Rainfall in Houston, Texas 77002

These readings estimate rain near this ZIP’s reference point, not an average across the entire ZIP. Use device location or search above for a more specific area. Nearby streets can receive different amounts during localized storms.

Today starts at midnight in the America/Chicago time zone. The 24-hour and 7-day totals are rolling windows through the displayed analysis time. Historical dates use local calendar days; the YTD graph compares the same completed dates with the 1991–2020 ERA5 average.

Local rainfall context for Houston, Texas 77002

Central Houston receives rain from Gulf moisture, warm-season thunderstorms, fronts, and tropical systems. Flat terrain and intense rainfall rates can create flooding concerns even when totals vary sharply across the metro area. A storm centered west, east, or south of downtown may not be represented well by the 77002 reference point.

Use the recent daily table to see when the estimated accumulation occurred, and compare the 24-hour total with the seven-day value for broader context. Radar estimates are useful for area coverage but can still differ from a maintained ground gauge. For flash-flood, tropical-weather, or severe-storm decisions, follow National Weather Service Houston/Galveston products and local emergency instructions.
