Weather Skill
This skill enables Nami to retrieve and present real-time weather conditions and forecasts for any city or region globally, using wttr.in with built-in fallbacks.
Instructions
1. Retrieve Data
When asked about the weather in a specific location, attempt to fetch raw JSON data from wttr.in using the web_fetch tool.
- URL Format:
https://wttr.in/<city_name_or_location>?format=j1
- Example:
https://wttr.in/Bangkok?format=j1
[!TIP]
If the city name contains spaces, replace them with + or use URL encoding (e.g., New+York or San+Francisco).
2. Parse JSON Response
From the returned JSON, extract the following details:
- Location Metadata:
nearest_area[0].areaName[0].value (to confirm the resolved city/region name) and nearest_area[0].country[0].value.
- Current Conditions (from
current_condition[0]):
temp_C: Current temperature in Celsius.temp_F: Current temperature in Fahrenheit.FeelsLikeC: "Feels Like" temperature in Celsius.FeelsLikeF: "Feels Like" temperature in Fahrenheit.humidity: Humidity percentage.windspeedKmph: Wind speed in km/h.weatherDesc[0].value: Brief weather description.
- Forecast (Optional, from
weather array):
- If the user asks for a forecast, extract the next 3 days'
date, maxtempC/mintempC, and general weather conditions.
3. Dynamic Emoji Mapping
Use the weather description or weatherCode to map appropriate emojis:
- Sunny / Clear:
Sunny, Clear ☀️
- Partly Cloudy:
Partly cloudy ⛅
- Cloudy / Overcast:
Cloudy, Overcast ☁️
- Mist / Fog:
Mist, Fog, Freezing fog 🌫️
- Patchy Rain / Light Drizzle:
Patchy rain nearby, Light drizzle, Light rain 🌦️
- Heavy Rain / Thundery:
Heavy rain, Torrential rain, Thundery outbreaks nearby 🌧️⛈️
- Snow / Ice:
Patchy snow nearby, Light snow, Heavy snow ❄️
- Windy:
Windy, Blowing snow 💨
4. Robust Fallbacks & Error Handling
wttr.in can occasionally be rate-limited or offline. Implement this robust fallback strategy:
- Empty/Invalid Response: If
web_fetch returns non-JSON text or fails with a rate limit error (e.g., 429 Too Many Requests), fall back immediately to a web search using search_web or Google Search for "current weather in <city_name>".
- Missing Fields: If some fields are missing from
wttr.in, omit only those specific details instead of failing the entire request.
5. Format Output
Construct an aesthetic, readable, and structured markdown response.
Example Current Weather Format:
### 🌤️ Current Weather in **Bangkok, Thailand**
* **Temperature:** 32°C (90°F) | *Feels like 36°C (97°F)*
* **Condition:** Partly cloudy ⛅
* **Humidity:** 74%
* **Wind Speed:** 12 km/h
* *Note: Weather times are local to the requested city.*
Example Forecast Format (if requested):
