## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

### 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.

| Who uses it | What they scrape Weather Underground for |
|---|---|
| Weather enthusiasts | Monitor hyperlocal conditions from their own or nearby personal weather stations |
| Researchers | Collect real-time weather data for climate studies or model validation |
| Smart home integrators | Pull local weather data to trigger automations based on current conditions |
| App developers | Get current weather observations for a specific location without API keys |

### What it does

This Actor collects current weather observations from Weather Underground personal weather stations by station ID, and returns each observation as a flat row with temperature, humidity, wind, pressure, and other metrics.

- 🌡️ **Current conditions:** temperature, feels like, humidity, dew point, and more.
- 💨 **Wind and pressure:** wind speed, direction, gusts, and barometric pressure.
- 🌧️ **Precipitation:** rain rate and daily accumulation where available.
- 📊 **Flexible units:** choose imperial (F, mph, inHg) or metric (C, km/h, hPa).
- 📦 **Bulk export:** get up to 1,000,000 observations per run for paid users.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

### What you can do with Weather Underground data

**🌦️ Monitor hyperlocal weather.**

A weather enthusiast tracks conditions from their backyard station and several nearby stations to understand microclimates.

**📈 Feed data to models.**

A researcher collects current observations from multiple stations to validate a short-term forecast model.

**🏠 Automate smart home.**

A homeowner pulls temperature and wind data from a local station to control irrigation or window shades.

**📱 Power a weather app.**

A developer uses station observations to display current conditions for user-selected locations without API overhead.

### Why choose this scraper

|  | What you get |
|---|---|
| **No API key** | Scrape public station pages without registering for Weather Underground API access |
| **Multiple stations** | Fetch observations from many station IDs in a single run |
| **Unit flexibility** | Get data in imperial or metric units to match your needs |
| **Flat output** | Each observation is a single row, ready for analysis or export |

### How it compares

This Actor focuses on current observations from personal weather stations on Weather Underground, while competitors may cover forecasts, historical data, or official NWS stations.

| Feature | ParseForge | Weather Data Scraper | NWS Weather Station Observations: Resolution-Grade Daily Highs | Prediction Market Resolution Evidence Checker |

### Configure the run

Drive the Actor with a list of personal weather station IDs, choose your units, and set a maximum number of observations to return. The Input tab lists every parameter.

A first run with the defaults:

```json
{
  "stationIds": [
    "KCASANFR1753"
  ],
  "units": "e",
  "maxItems": 10
}
```

A larger pull:

```json
{
  "stationIds": [
    "KCASANFR1753"
  ],
  "units": "e",
  "maxItems": 200
}
```

### Pricing

Pay-per-result: **$0.004 per result** collected. You pay only for the results written to your dataset.

| Results collected | Approximate cost |
|---|---|
| 100 results | $0.40 |
| 1,000 results | $4.00 |
| 10,000 results | $40.00 |

New Apify accounts start with $5 in free credit.

### Free users

Free-plan runs return up to 10 results as a preview. [Upgrade your Apify plan](https://console.apify.com/sign-up?fpr=vmoqkp) to collect up to 1,000,000 results per run.

### Run it

1. [Create a free Apify account with $5 in credit](https://console.apify.com/sign-up?fpr=vmoqkp).
2. Open the [Weather Underground Observations Scraper](https://apify.com/parseforge/wunderground-observations-scraper?fpr=vmoqkp).
3. Set your inputs and any filters, then click **Start**.
4. Export the results as CSV, Excel, JSON, or XML from the **Dataset** tab.

Run it programmatically through the [Apify API](https://docs.apify.com/api/v2) (`run-sync-get-dataset-items`) or the [ApifyClient](https://docs.apify.com/api/client/js) for JavaScript and Python.

### Use with AI agents (MCP)

Give an AI agent live access to Weather Underground through the Model Context Protocol. Add the Actor to Claude, Cursor, or any MCP client:

```bash
claude mcp add --transport http apify "https://mcp.apify.com/?tools=parseforge/wunderground-observations-scraper"
```

Then prompt it in plain language to run the scraper and read back the results.

### 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.

### FAQ

| Question | Answer |
|---|---|
| What is a personal weather station ID? | It's a unique identifier for a station on Weather Underground, like KCASANFR1753. You can find it in the URL of a station's page or by searching on the site. |
| Do I need an API key? | No, this Actor scrapes the public station pages directly, so no API key or registration is required. |
| How many observations can I get? | Free users are limited to 10 items as a preview. Paid users can set maxItems up to 1,000,000. |
| Can I get historical data? | This Actor focuses on current observations. For historical data, consider a different scraper or the official API. |
| What units are available? | You can choose imperial (F, mph, inHg) or metric (C, km/h, hPa) via the units input. |
| How do I find station IDs? | Search for a location on Weather Underground, click on a personal weather station, and the ID is in the URL or page header. |
| Can I scrape multiple stations at once? | Yes, provide a list of station IDs in the stationIds input field. |
| What output formats are supported? | You can export the results to CSV, JSON, Excel, or XML from the Apify dataset. |
| Is this legal? | Scraping public data is generally allowed, but you should review Weather Underground's terms of service and respect robots.txt. |
| How often can I run this? | You can schedule runs as frequently as you need, but be mindful of the website's load and your Apify plan limits. |
