Expect more unseasonably cool weather and maybe some rain across San Diego County this week
The latest in a series of low-pressure systems will move in late Tuesday and last through Wednesday, keeping the air brisk across the region.
Memorial Day is only three weeks away. But it won’t feel like the unofficial start of summer is near this week. Daytime highs will again stay below average, especially at the coast.
The National Weather Service says the latest in a series of low-pressure systems will cycle through San Diego County, possibly bringing scattered showers late Tuesday and Wednesday.
The daytime high in San Diego will be 66 on Monday, 64 on Tuesday and Wednesday, 66 on Thursday, and 69 on Friday and Saturday. The seasonal average is 70. So far, San Diego’s average May temperature is running about 3.1 degrees below average and could slip more as the week goes along.
The mid-week moisture and onshore winds will keep temperatures 5 to 20 degrees below normal, with the biggest drop in the mountains, the weather service said.
Patchy fog could form along the coast on Wednesday and Thursday nights.
Although the air has been cool, sea-surface temperatures have climbed a bit and are now in the 60- to 62-degree range at most beaches. At some spots, including Del Mar and Solana Beach, tiny little sea creatures known as Velella vellela (or by-the-wind sailors) are continuing to wash ashore in large numbers.
Scripps Oceanography says onshore winds and abundant food have led to a rare mass stranding that’s caught the attention of surfers and beach-goers.
The marine layer might recede enough on Thursday night for skygazers to watch the International Space Station fly overhead. NASA says the station should be visible for five minutes, starting at 8:42 p.m. The outpost will first be visible 10 degrees above the south-southwest horizon. It will track to the east-northeast, low in the sky.
