forecast.hours 端點會針對特定地點傳回最多 240 小時的預測資訊，從目前小時開始。API 會傳回以下內容：
您可以透過 APIs Explorer 提出即時要求，熟悉 API 和 API 選項：
關於每小時天氣預報要求
如要要求每小時天氣預報資訊，請傳送 HTTP GET 要求至：
https://weather.googleapis.com/v1/forecast/hours:lookup?key=YOUR_API_KEY&location.latitude=LATITUDE&location.longitude=LONGITUDE
請在要求網址參數中加入位置的經緯度座標。
每小時天氣預報要求範例
根據預設，forecast.hours 端點會從目前的時間開始，傳回 240 小時的資料。您可以使用 hours 參數，將要求範圍限定在特定時間範圍內。
以下範例會要求加州山景市未來三小時的每小時天氣預報資訊：
curl -X GET "https://weather.googleapis.com/v1/forecast/hours:lookup?key=YOUR_API_KEY&location.latitude=37.4220 &location.longitude=-122.0841 &hours=3"
在回應中，interval 物件會指出每小時的資訊：

指定每頁要傳回的時間數量
您可以使用 pageSize 網址參數，指定每頁傳回的資料時數。預設值為每頁 24 小時的預測資訊。
包含多頁資訊的回應會附上 nextPageToken。如要查看下一頁資訊，請將 nextPageToken 值傳遞至要求中的 pageToken 參數。
以下範例會要求加州山景市的 25 小時天氣預報資料，每頁顯示 3 小時的資料：
curl -X GET "https://weather.googleapis.com/v1/forecast/hours:lookup?key=YOUR_API_KEY&location.latitude=37.4220 &location.longitude=-122.0841 &hours=25&pageSize=3"
