What is the water temperature at Edisto buoy?

Water temperature at the buoy is 84.0°F. That is 0°F cooler than on July 28.

Why are some fields blank?

Waves are sampled every 30 minutes and pressure tendency is computed hourly, so most 10-minute rows carry no value for them. NDBC prints “-” (or “MM” in the raw feed). A field that stays blank for days usually means a sensor fault; NDBC lists outages on its station status page.
