It’s hot here in Lodi, we know. But how long has it been hot? And when will we see some relief?
The last seven days have all crossed that much-dreaded century mark, peaking at 107 on Tuesday. That’s got to be some kind of record, right?
Not quite, says meteorologist Stefanie Henry of the National Weather Service in Sacramento.
The longest century streak in Lodi during July came in 1960, with nine days of heat topping 100 degrees that finally ended on July 25. It hit a high of 106 on July 20.
More recently, there was a seven day-heat wave in July 2006, with a high of 110 degrees on July 23. The heat fell back below 100 after July 26.
What about June, since our current heat wave got started last month?
Lodi’s June record was set in 1976, when the temperature passed 100 degrees for six days in a row. The highest temperature was 106 on June 27. The streak ended two days later.
Ideally, this heat will have mellowed by August, but that month has a century streak record, too.
Six days in August 1996 topped 100 degrees, ending on Aug. 15. The temperature hit 103 on Aug. 10 and 13 that year.
So when will this be over? July 4 saw 104 degrees. Temperatures should begin dropping today, to the mid- to high 90s for about a week. Next weekend may see a few days back above that century mark.
Meteorologist Ken Clark of AccuWeather.com, a private weather forecasting firm, says the really unusual heat in San Joaquin County has been in the southern portion of the county. On Wednesday morning, the National Weather Service issued an excessive heat warning for much of southern San Joaquin County.
Surprisingly, the agriculture industry is faring decently in the heat. Joe Valente, orchard and vineyard manager, says the main crops are either pre-harvest or not yet mature, so everything is doing OK.
Grapes, apples and walnuts could lose a little crop yield due to sunburn, so many growers are spraying a white covering to protect the produce from the sun.
Tomatoes and bell peppers are very young on the vines right now, so the change in weather from last week’s cool rain to this week’s heat is a tough transition.
“They’re just not acclimated to switch to the hot weather. It seems like it went from mild right to warm,” Valente said.
But with a touch of extra irrigation and a forgiving evening breeze, no major crop disasters are anticipated.
