It will be a cooler day for the Central Coast, especially as the marine layer may decide to linger along the coast through most of the day. However, away from the coastline, the inland valley communities will be much cooler than what the Central Coast is used to this time of year. Paso Robles has a forecasted daytime high of 71 degrees. That's 20 degrees below the average for this time of year of 91 degrees. For some of the deeper interior valleys, the daytime high will be a little warmer compared to Paso Robles, with the potential to reach the mid-80s.
Most of the coastal valleys will have average temperatures, ranging from the upper 60s to the low 70s. At the coast, daytime highs will stay closer to the mid to upper 60s. The "No Sky July" motto could ring true for the beaches Thursday as the marine layer could be stubborn to clear.
Looking ahead to the weekend, there is definitely going to be a shift in the forecast. High pressure is going to rebuild over New Mexico and push into southeastern California, which will have local impacts. Daytime highs for the inland valleys are expected to reach the upper 90s to the low 100s. Coastal valleys could reach the mid-80s and the beaches will reach the mid-70s.
A beach hazards statement has been put in place for the July 4th weekend as elevated surf is expected to develop Friday through Sunday. During this time frame, the surf will be from six to nine feet with local sets up to 10 feet.
