Marine Weather

Overview

Marine Weather works by retrieving the marine weather data from various reliable weather sources and providing it in a structured format. You can expect accurate and up-to-date information.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

curl "https://api.apiverve.com/v1/marineweather?lat=29.48003&lon=-37.62424" \

package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/marineweather?lat=29.48003&lon=-37.62424", nil)
	req.Header.Set("x-api-key", "your_api_key_here")

	res, err := http.DefaultClient.Do(req)
	if err != nil {

	fmt.Println(string(out))
}

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

Use cases

Voyage Route Planning

Commercial shipping dispatchers evaluate maximum wind speeds and precipitation totals along projected corridors to steer vessels away from rough open-sea conditions.

Offshore Fishing Charters

To protect offshore anglers, booking platforms check marine weather conditions, humidity levels, and UV indices before confirming deep-sea reservations.

Regatta Safety Monitoring

When organizing coastal sailing competitions, race committees monitor wind thresholds and precipitation to schedule offshore heats during safe operating windows.

Port Logistics Scheduling

Cargo terminal coordinators track offshore forecast conditions and daylight hours to prepare docking tugs and crane crews for inbound container vessels.

Other ways to use Marine Weather

Set up Marine Weather on APIVerve, or reach the same source a different way. Your APIVerve account and credits work on all of them — one key, one balance.
