A long and grueling heat wave brought record-setting temperatures to San Diego County, according to the National Weather Service.

Not only did some areas reach record-setting daytime high temperatures during the stretch of hot weather that spanned from last Wednesday to Tuesday, but some areas reached record-high daytime lows, which means, for many, there was little relief from the heat overnight.

How hot was it during this heat wave?

Here are the record-breaking daytime highs reached in San Diego County:

  • Vista: 98 degrees on Monday, which broke record of 97 set in 2015
  • Escondido: 104 degrees on Monday, which broke the record of 103 set in 1956
  • Escondido: 109 on Sunday, which broke the record of 104 set in 1944
  • Ramona: 110 on Sunday, which broke the record of 103 set in 2018
  • Alpine: 105 on Sunday, which broke the record of 104 set in 1984
  • El Cajon: 108 on Sunday, which broke the record of 104 set in 1984
While cooler weather is on the way, today’s heat was still oppressive, which means people are still dealing with it and having to work in it, reports NBC 7’s Todd Strain.

Several areas set or tied records for the warmest minimum temperatures reached, meaning these were the hottest overnights for these dates on record:

  • On Monday, Apline tied its minimum temperature record of 77 set in 1979
  • On Monday, Borrego tied its minimum temperature record of 84 set in 1999
  • Vista: 73 degrees on Sunday, which broke the record of 70 set in 2022

  • Borrego: 85 degrees on Sunday, which broke the record of 82 set in 2021
  • On Sunday, San Diego tied its minimum temperature record of 75 set in 2022

The NWS said the stretch Escondido experienced its warmest average minimum temperature stretch for Sept. 6-8.
