# How to Build Weather Marketing Triggers with Claude

Claude designs weather-triggered marketing with analytical precision, checking conditions across target markets and matching them to campaign activation criteria. It asks about your products and audience to build custom trigger rules linking specific temperature ranges, precipitation types, or UV levels to your most relevant campaigns.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "What is the current weather in New York, LA, and Chicago?"
3. Claude returns conditions for each city with temperature, precipitation, and humidity
4. Ask: "Which cities should get our cold weather promotion based on these conditions?"

## Example Prompt

```
Check weather in our top 10 markets. Which cities are having a heat wave? I want to trigger our summer sale campaign in those markets.
```

## Tips

- Define clear triggers: "Rain above 70% = indoor activity promotion"
- Ask Claude to check weather in all your target markets at once
- Combine weather triggers with time-of-day for maximum relevance
