In short, hundreds of thousands at least. If you include ocean monitoring meteorological stations not limited to buoys, likely in the millions.
Weather buoys are deployed by so numerous organizations no complete list could be reasonably compiled. Many networks are integral to modern safety standards on the sea. Scientific organizations keep incomplete lists insofar as they need to share or corroborate data. It is common for scientific bodies to deploy thousands, and this data is supplemented by meteorological stations on the shore, oil rigs, and on board ships to give a more complete picture.
There are few international laws applying to buoys in international waters, and every major world military maintains its own uncompromisable network as a measure of national security (which is shared only after it is deemed tactically obsolete should a conflict break out). This is supplemented by the meteorological stations now common on board any modern war vessel, and more and more commonly on commercial vessels.
Fixed buoys provide a stable and permanent navigational aid for ships and boats. They are cost-effective as they do not require regular maintenance or relocation. Fixed buoys also offer reliable marking of hazards and channels in all weather conditions.
People use various tools to predict hurricanes, including satellites to track weather patterns, weather buoys to monitor sea conditions, weather radar to detect storms forming, and computer models to forecast the path and intensity of the storm. Additionally, meteorologists analyze data from weather stations, aircraft reconnaissance, and historical patterns to predict hurricane formation.
There are thousands of weather stations around the world, with estimates ranging from 10,000 to 15,000 stations. These stations collect data on various weather parameters that help in forecasting and monitoring weather conditions globally.
Weather satellites, weather radars, weather buoys, and aircraft reconnaissance are commonly used to detect and track tropical storms. These devices provide valuable data on the formation, movement, and intensity of tropical storms, helping meteorologists issue timely warnings and forecasts to protect communities from potential hazards.
Instruments such as thermometers, satellites, buoys, and weather stations are commonly used to measure climate change indicators like temperature, precipitation, sea surface temperature, sea-level rise, and greenhouse gas concentrations in the atmosphere. These instruments provide data that scientists use to monitor and study changes in Earth's climate over time.

Mid channel buoys
I am not certain I understand the question, but yes there are red buoys in the US. The red buoys are on the right side of the channel when returning from sea. They are even numbered and unlit buoys are called "Nun" buoys. The US is in the IALA-B (International Association of Lighthouse Authorities) The "B" Region covers North and South America, Japan, South Korea and the Philippians. IALA-A Covers the rest of the world.
Regulatory Buoys.
The World Meteorological Association offers information on world weather forecasts on their website World Weather. One could also check The Weather Channel for updates on many popular destinations.
Anchor or mooring buoys do not have lights
Satellite imagery and readings from buoys at sea report the present weather conditions. This information is entered into computerized forecast models, which try to predict that the weather, including the hurricane, will do.
