Weather Underground Observations Scraper

Weather Underground Observations Scraper

Scrape Weather Underground personal weather station observations by station ID, with imperial or metric units. Get temperature, humidity, wind, pressure, and more for any PWS. Export to CSV, JSON, Excel, or XML.

Weather Underground's official API requires an API key and has rate limits. This Actor reads public personal weather station (PWS) observation pages directly, so you can pull current conditions for any station ID without registration. It returns each observation as a flat row with all available weather metrics.

Troubleshooting

Why am I getting no results?

Check that the station IDs are correct and active. Some stations may be offline or no longer reporting. Try a known ID like KCASANFR1753.

Why is the data incomplete?

Not all stations report all metrics. Weather Underground may not have every field for every station. Check the station's page to see what it reports.

Why am I limited to 10 items?

Free Apify users are limited to 10 items as a preview. Upgrade to a paid plan to increase maxItems up to 1,000,000.

Why did the run fail?

The website may be blocking requests or the station ID is invalid. Try again later or verify the ID. If the issue persists, contact support.
