it sure is. when it hits 70 in ocean shores the local people start melting. whenever the forecast for the interior is suggesting 80 degrees the line of traffic to the beach is non-stop. its the place to go to beat the heat. as the heat in the interior makes the air rise, it pulls the low temp air from over the ocean inland and we get that cold misty condition. it's amazing to see actually, and you see the temperature drop 20 degrees in about 1/8 of a mile.
i don't care for that too much, but we're usually out cruising during the summer and miss it. spring and fall at the coast are spectacular in my opinion.
