Implementation notes
When to use WeatherAPI.com
WeatherAPI is worth considering when you need 1 million calls/month on a free plan — it is by far the most generous free tier in the weather category. It covers current conditions, 3-day forecasts, historical data back to 2010, astronomy data, and marine weather under one key.
Common pitfalls
- The free tier caps historical data at the last 7 days. Requests for dates older than 7 days return a 403 even though the endpoint exists; upgrading to a paid plan unlocks the full archive back to January 1, 2010.
- Marine and air quality endpoints require separate feature flags enabled in the dashboard. A valid key without those flags enabled returns a 403 with an unhelpful 'access denied' message rather than a clear explanation.
- WeatherAPI's JSON structure for forecast days nests inside `forecast.forecastday[].hour[]` — the hourly array is zero-indexed from midnight local time, not UTC. This trips up developers who assume UTC alignment.
- The free plan does not include bulk/batch requests. Each location requires a separate HTTP call, which matters for dashboards monitoring 50+ locations simultaneously.
