The new endpoint is /campingreport/{campsiteId}. This endpoint is for campers who want to check things like rain chances and temperature to determine whether they should head out to a camping location. {campId} is retrieved from a list of camping sites.

Optional parameters:

Number of days: Max is 7. Default is 3. Optional.
Units: imperial or metric. With imperial, you get feet and knots. With metric, you get centimeters and kilometers per hour. Optional.
Time: time of the day corresponding to time zone of the campsite you're inquiring about. Format is unix time, aka epoch. Unix time is the milliseconds since 1970. Time zone is GMT or UTC. Optional.

{campaign_id} If you include the hour, then you only get back the campsite condition for the hour you specified. Otherwise, you get back 3 days, with conditions listed out by hour for each day.

The response will include the surf temperature, rain chances, and overall recommendation.
