It has been a scorching start for fall and Monday got even hotter.
As of 10 a.m., temperatures were already much warmer than previously projected. Miramar, for example, reported 107 degrees well before noon. Imperial Beach is sitting at 99, which is about 10 degrees hotter than was expected at the peak of the afternoon heat, around 3 p.m., according to forecaster Whitney Southwick.
Most of the day's highs were set before noon, as it turned out. In Oceanside, the mercury crested at 102 degrees, while the day's high temperature at Del Mar was 96. Escondido residents sweltered in 105 degree heat; not far away in Ramona, the thermometer peaked at 106. Folks living near Lindbergh Field, however, never got hotter than 92 degrees.
The official all-time mark was set in 1963, when it hit 111 degrees on Sept. 26. That following day, it hit a 104.
Although low pressure is moving in and the high pressure will start moving out, Tuesday will still be warm.
“This means partly-cloudy conditions the next few days, along with more humidity and even the chance -- a slight chance -- but still, a chance, of some isolated or scattered showers or thundershowers,” Southwick said.
There could also be some dry lightning strikes, so the fire danger remains high through the week.
“Highs should drop off by 10 to 15 degrees west of the mountains, but because of the mugginess, it will still feel pretty hot,” Southwick said.
Cooler marine air will relieve the county later in the week, and temperatures will continue to decline, dropping back to the mid-70s to mid-80s.
