CVTEMP is a community-driven platform for monitoring, mapping, and predicting temperature across California's Central Valley — powered by NOAA data and local expertise.
The Central Valley spans over 22,000 square miles and is one of the most agriculturally productive regions in the world. Temperature extremes directly impact crops, communities, and ecosystems — which is why accurate, hyperlocal data matters.
CVTEMP brings together NOAA weather station data, community-contributed observations, and machine learning prediction models to deliver the most accurate temperature intelligence available anywhere in the valley.
High-resolution temperature maps updated every 15 minutes from 47 stations. Visualize micro-climate variations at neighborhood scale across all 22,000 sq mi.
72-hour forecasts powered by NOAA data and ML models trained on 20+ years of valley climate history. 98.3% accuracy verified across all monitoring zones.
Submit observations, access open datasets, and collaborate with agricultural experts, climate scientists, and local communities contributing from across the valley.
Integrate real-time and historical temperature data directly into your apps, dashboards, or agricultural management systems via our fully open REST API.
20+ years of historical temperature records for every station. Analyze long-term trends, seasonal shifts, and climate change impacts across the valley over time.
Set custom thresholds and receive instant alerts for heat advisories, frost warnings, and anomalous conditions at the stations and regions you care about most.
"CVTEMP's granular data fundamentally changed how we model heat stress impacts on almond orchards. Nothing else comes close for Central Valley specificity."
From farm operators tracking heat stress windows to climate scientists building regional models — CVTEMP brings together everyone who depends on understanding temperature in the valley.
Join a growing community contributing observations, sharing research, and making open climate data accessible for all.
Free access to live maps, historical data, forecasts, and community tools.
No credit card required.
