The pattern is a long, easy season. Eleven months score 80 or higher, with July at 98 and June at 97. Only February (74) drops below, in the middle of a wet stretch that averages 6.1 rainy days.
Nights stay cool even in summer. July averages 78°F by day and 54°F at night, so an evening reception wants layers.
If your venue is inland toward Paso Robles, expect more heat than this reading. If it's on the coast at Morro Bay or Pismo Beach, expect more fog and a few degrees less.
