Marine Weather is a simple tool for getting marine weather data. It returns the current weather conditions in coordinates within the ocean and sea.

The Marine Weather API provides reliable and fast access to marine weather data through a simple REST interface. Built for developers who need consistent, high-quality results with minimal setup time.

To use Marine Weather, you need an API key. You can get one by creating a free account and visiting your dashboard.

GraphQL AccessALPHA

Access Marine Weather through GraphQL to combine it with other API calls in a single request. Query only the marine weather data you need with precise field selection, and orchestrate complex data fetching workflows.

Test Marine Weather in the GraphQL Explorer to confirm availability and experiment with queries.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

    input: {
      lat: 29.48003

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The Marine Weather API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Marine Weather directly from browser-based applications without proxy servers.

CORS HeaderValueDescription
Access-Control-Allow-Origin*Accepts requests from any origin
Access-Control-Allow-Methods*Accepts any HTTP method
Access-Control-Allow-Headers*Accepts any request headers

Browser Usage: You can call Marine Weather directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Rate Limiting

Marine Weather API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Marine Weather users.

PlanRate LimitDescription
Free5 requests/minHard rate limit enforced - exceeding will return 429 errors
StarterNo LimitProduction ready - standard traffic priority
ProNo LimitProduction ready - preferred traffic priority
MegaNo LimitProduction ready - highest traffic priority

Learn more about rate limiting →

Rate Limit Headers

When rate limits apply, each Marine Weather response includes headers to help you track your usage:

HeaderDescription
X-RateLimit-LimitMaximum number of requests allowed per time window
X-RateLimit-RemainingNumber of requests remaining in the current window
X-RateLimit-ResetUnix timestamp when the rate limit window resets

Handling Rate Limits

Free Plan: When you exceed your rate limit, Marine Weather returns a 429 Too Many Requests status code. Your application should implement appropriate backoff logic to handle this gracefully.

Paid Plans: No rate limiting or throttling applied. All paid plans (Starter, Pro, Mega) are production-ready.

Best Practices for Marine Weather:

  • Monitor the rate limit headers to track your Marine Weather usage (Free plan only)
  • Cache marine weather responses where appropriate to reduce API calls
  • Upgrade to Pro or Mega for guaranteed no-throttle Marine Weather performance

Note: Marine Weather rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Marine Weather on Free tier.

Error Codes

The Marine Weather API uses standard HTTP status codes to indicate success or failure:

CodeMessageDescriptionSolution
200OKRequest successful, data returnedNo action needed - request was successful
400Bad RequestInvalid request parameters or malformed requestCheck required parameters and ensure values match expected formats
401UnauthorizedMissing or invalid API keyInclude x-api-key header with valid API key from dashboard
403ForbiddenAPI key lacks permission or insufficient creditsCheck credit balance in dashboard or upgrade plan
429Too Many RequestsRate limit exceeded (Free: 5 req/min)Implement request throttling or upgrade to paid plan
500Internal Server ErrorServer error occurredRetry request after a few seconds, contact support if persists
