How windy is it at Galveston buoy 42035?

What is the water temperature at Galveston buoy?

Water temperature at the buoy is 87.4°F. That is 2°F warmer than on July 14.

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.
