Openweathermap Rate Limits

Rate limit definitions for the OpenWeather API surface across all subscription tiers. Captures per-minute call ceilings, per-month quotas, response signaling, and recovery semantics.

Openweathermap Rate Limits is the machine-readable rate-limit profile for OpenWeatherMap on the APIs.io network, in the API Commons Rate Limits shape.

It captures 12 rate-limit definitions, across the free, startup, developer, professional, and expert tiers, measuring requests_per_minute, requests_per_month, and requests_per_day.

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 5 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, and serviceUnavailable.

Tagged areas include Weather, Forecast, Air Pollution, Rate Limiting, and Quotas.

Policies

Backoff Strategy
Clients should implement exponential backoff with jitter and honor the Retry-After header.
Quota Reset
Monthly quotas reset at the start of each calendar month in UTC. Per-minute windows reset on a sliding-window basis.
One Call Daily Window
One Call 4.0 daily counter resets at 00:00 UTC; calls in excess of 1,000 per day are billed at the published per-call price.
Tier Switching
Plan changes take effect at the start of the next billing cycle unless explicitly accelerated by OpenWeather support.
Fair Use
Even on uncapped enterprise contracts, sustained traffic that materially impacts shared infrastructure may be subject to fair-use throttling.
