Not as breezy today, but still hot and humid, with potentially dangerous heat in the upper valley and Rio Grande plains. Heat index values will range today between 105 and 110 degrees across deep south Texas and the Rio Grande Valley. Drink plenty of water and wear light-weight, light colored and loose fitting clothing when outside with plenty of sunblock. If you’re headed for the coastal waters, expect a moderate chop on the Laguna Madre with seas of 2-4 and occasionally 5-6 feet in the Gulf, mainly near and beyond 20 nautical miles.
A low risk for rip currents is expected today along the beaches of South Padre Island and at Boca Chica State Park. Even though the rip current risk is low today, life threatening rip currents are still possible, especially in the vicinity of the South Padre Island Jetties. Expect partly cloudy skies today with southeasterly winds of 15 to 20 mph in the afternoon. Bring the sunscreen as the UV index exists within the extreme range. Stay hydrated with today’s high temperature around 90 and heat index in the 101-106 degree range. Have a fun and safe day at the beach!
