multi-day snowfall records, and

required an extensive recovery period

that lasted through March. On 3.1,

convective showers brought brief

snow down to 1,000 feet elevation in

Anaheim, Brea, Yorba Linda, Canyon

Lake, San Bernardino and Desert Hot

Springs.

Impacts included numerous people

trapped in homes, damaged gas

lines leading to some house fires,

collapsed roofs, and highway and

street closures that lasted up to

three weeks. Boats on Lake

Arrowhead grew top heavy in deep

snow and overturned, which also

damaged docks. Numerous rescues

were made and thousands used

safety shelters. At least one death

was attributed to the storm. An

avalanche 15 feet deep blocked

portions of the Mount Baldy Road

on 3.1.

was identified as a tropical storm in

California before NOAA/NHC

researchers later determined in

February 2024 that Hilary had lost

tropical storm status just before

crossing into Southern California.)

5.21.2000

A strong ridge of high pressure built

over the region in the wake of storm

system over the Intermountain West.

Temperatures in the Inland Empire

and Coachella Valley subsequently

soared, with Riverside reaching 105°

and Palm Springs topping out at 113°.

5.7-9.2001

Heat wave. 109° at Palm Springs,

Thermal, and Borrego Springs, 103° at

Hemet, 102° San Bernardino.

9.1.2002

Tropical heat wave: 118° at Dulzura,

113° Temecula, 112° Riverside and

Menifee. Sharp temperature gradients:

77° at Newport Beach to 107° Santa

Ana (10 miles), 72° Oceanside Harbor

to 87° Oceanside Airport (2 miles),

81° Sea World to 91° San Diego -

Lindbergh Field (3 miles).

3.21.2004

This day fell in the middle of a three-

day heat wave in the deserts, brought

on by a strong area of high pressure

over the Western US. Thermal

recorded its highest temperature in

March with a reading of 103°, while

Mecca reached 107°.

4.26-27.2004

Record highs for April were set. On

4.26: 103° at Wild Animal Park, 100°

at Yorba Linda. On 4.27 it was 85° at

Idyllwild.

7.10-20.2005

Strong high pressure brought a lengthy

heat wave to the region. 121° in

Thermal, 120° in Palm Springs and

Borrego Springs, 116° in Hesperia.

Big Bear Lake tied their all-time

record at 94° on 7.18. 98° at Idyllwild.

Low temperature at Indio was 90° on

7.13.

One death in the Anza Borrego

Desert. Near record power

consumption.

7.22.2006

A major heat wave with humidity, in

some ways unprecedented, hit

Southern California. 121° in Palm

Springs, 120° at Indio and Thermal,

114° at Ontario and the Wild Animal

Park, 113° at El Cajon. It was 112° at

Escondido and 109° in La Mesa (both

highest all time). Record minimum

temperatures were recorded in most

places. Desert locations reported the

all-time warmest month on record. Sea

temperatures hit 80°.

16 were killed from the heat, and

many more were treated. Some

power outages occurred.

7.3-6.2007

A major heat wave struck the

mountains and deserts. A strong

persistent marine layer precluded the

heat wave from impacting the coasts

and valleys. 119° in Ocotillo Wells,

116° in Palm Springs and Indio, 115°

in Anza Borrego, 107° in Julian, 103°

at Lake Cuyamaca, 100° at Idyllwild,

97° at Palomar Mountain, 94° at Big

Bear Lake (ties all time high) and Mt.

Laguna.

Some heat illnesses, poorly

documented.

9.1-3.2007

A heat wave with a monsoon flavor.

Temperatures exceeded 95° in the

coasts and the mountains, 105° in the

valleys, 110° in the Inland Empire and

high deserts, and 115° in the lower

deserts.

At least six deaths from heat related

illnesses.

5.20.2008

An intense heat wave that induced

record temperatures over the coast and

valleys the prior two days shifted to

the deserts on this day. The afternoon

high in Palm Springs reached 113°.

6.16-23.2008

A prolonged heat wave that lingered

for nearly a week peaked on 6.21 in

the valleys, mountains and deserts.

Highs reached 117° in Palm Springs,

and 114° in Indio. West of the

mountains Ramona recorded a high of

107° while San Diego reached 92°.

1.12.2009

The minimum temperature at Santa

Ana of 73° not only set a record high

minimum temperature for the date and

month, but also for the entire winter

season. Incredibly, the minimum is

tied for the 23

highest minimum

temperature on record (and this was in

January!). This reading was 26

degrees higher than the average low

temperature and three degrees higher

than the average high temperature.

Persistent Santa Ana winds and strong

high pressure were the causes.

9.27.2010

Strong high pressure and offshore

flow led to record high temperatures

for many stations. Los Angeles

reached their all-time high

temperature of 113°. Santa Ana’s 112°

just missed the all-time mark by one

degree. Numerous high temperature

records for the month of September

were broken. This fall heat followed

the coolest summer since 1933.

11.3-4.2010

Strong high pressure and offshore

flow led to all-time November record

high temperatures. At San Diego it

reached 100° on 11.4, the highest

temperature on record in November,

and the only time it has reached the

century mark in November. This was

also the first time a 100 degree reading

was reached in more than 21 years. In

Riverside, the temperature of 99° on

11.3 tied and the 101° reading on 11.4

broke all time November records. On

11.3 it was 101° in Santa Ana,

equaling the highest November

temperature on record. And it was 96°

in Laguna Beach, the second highest

November temperature on record.

06.28-30.2013

A heat wave on the order of a 20 year

event enveloped the west and

Southern California. Death Valley hit

highest U.S. June temperature ever

recorded: 129° on 6.30. Other desert

cities like Palm Springs, Thermal, and

Borrego Springs tied or set new June

records and came within one degree of

the all-time highest temperature on

record on 6.29.

4.30-5.1.2014

On 4.30 temperatures soared past 90°

along the coast, breaking many daily

high temperature records. Winds kept

the minimum temperature in Anaheim

at 77°. On 5.1 temperatures at all

lower elevation stations were in the

90s, with Chula Vista topping the list

at 100°.

5.13-15.2014

Strong high pressure and a strong late-

season Santa Ana wind event

combined to bring record high

temperatures exceeding 100° to most

of the lower elevations these days.

Many all-time high temperature

records for the month of May were

broken. The hottest day was 5.15

when it was 106° in Yorba Linda and

San Diego Wild Animal Park.

3.13-16.2015

Strong high pressure and Santa Ana

conditions boosted temperatures into

the 90s across the coast and valleys

each day, and cooling only into the

60s at night. Numerous daily high

maximum and daily high minimum

records were set. The warmest day on

3.13 was 96° in Santa Ana. Highest

minimum temperatures were 68° in

Santa Ana and San Diego on 3.15.

2.2016

February 2016 will go down as the

warmest February in history. In San

Diego the average high temperature

was 74.4°, a whopping 9.4° above

average and close to the average high

temperature in July. The average

temperature was 63.9°, four degrees

above average and close to the

average May temperature.

6.20.2016

An intense heat wave peaked on this

day with a total of 13 daily high

temperature records set. Borrego

Springs tied an all-time record high of

122°. Palm Springs reached 122°, an

all-time record for June and the

second highest temperature on record.

Indio and Thermal both reached 121°,

the second highest temperatures on

record for June. West of the mountains

Riverside was 114°, while Ramona

(109°) and El Cajon (107°) both set

records for June.

6.20, 6.24,

6.25, 7.7.2017

Strong high pressure sends the

temperature soaring to 122° in Palm

Springs on each of these days. These

are four of only eight days on record

to reach 122°. (Only three days on

record have reached 123°, the all-time

highest temperature.)

9.1-3.2017

A strong upper level ridge of high

pressure over the Great Basin and

weak offshore flow brought a heat

wave, particularly west of the

mountains. It was 114° in Ontario and

Chino, 112° in Riverside, 109° in

Ramona, 108° in Fallbrook, 106° in

Fullerton and El Cajon.

Many schools were closed near the

coast on 9.1, especially in San

Diego County.

10.23-25.2017

High pressure aloft and Santa Ana

Winds combined to bring record

breaking temperatures quite late in the

season. On 10.24, Vista and Poway

both peaked at 107°, while it was 106°

at the airports at Oceanside, Fullerton

and John Wayne. El Cajon and

Huntington Beach hit 105°.

85 schools in San Diego made early

releases on all three days.

11.22.2017

High pressure and offshore flow

boosted temperatures into the 90s,

with Anaheim topping out at an

incredible 100°.

7.6.2018

Strong broad upper level high pressure

centered over Nevada and unusual

weak offshore flow in July brought

extreme hot weather. Mecca reported

121° and Thermal hit 120°. A 120-

degree reading in Chino matched the

all-time highest temperature ever

recorded in the coastal basin of

Southern California. Several all-time

records fell, including 118° (tie) in

Riverside, 117° in Ontario and

Ramona, and 116° in Fullerton.

7.25.2018

Hot and dry summertime conditions

fell over the mountains. The Cranston

fire developed and led to the

formation of pyro-cumulonimbus

clouds and even some lightning.

The Cranston Fire was started by an

arsonist along Highway 74 between

Hemet and Mountain Center. Over

the course of two weeks, the fire

burned 13,139 acres south of

Idyllwild. Over 7,000 people had to

be evacuated from the area.

8.6.2018

Hot and dry summer conditions along

with the terrain, led to the start and

spread of the Holy fire

The fire started in the afternoon in

Trabuco Canyon, and exploded

over the next few days, scorching

over 23,000 acres. It forced the

evacuation of over 20,000 people

from the Lake Elsinore area, and

destroyed 18 buildings. It went on

to burn for well over a month, and

was eventually contained on 9.16.

8.5.2019

Hot weather hit the Coachella Valley.

Palm Springs recorded its highest

temperature of the year at 121°, tied

for the 12th hottest day all-time.

Ocotillo Wells and Thermal reached

120°.

9.5-6.2020

A major heat wave struck the region

that in some ways and for some areas

was unprecedented. On 9.6,

temperatures of 121 degrees were

recorded in Woodland Hills (the

highest temperature on record in Los

Angeles County) and in Chino. These

two records represent the highest

readings on record in Southern

California’s coastal basin. Climate

stations in El Cajon, Alpine and

Escondido achieved their all-time

highest temperatures on record for any

day on 9.6. Idyllwild achieved that

feat on 9.5, but that record lasted all of

one day as it was eclipsed on 9.6.

The Bobcat, El Dorado and Valley

fires started, and would grow into

major fires.

6.15-18.2021

Strong high pressure brought a dry

heat to inland areas. Temperatures

reached 123° in Palm Springs on 6.17,

tying the highest reading on record. It

was also 123° at Ocotillo Wells on

6.17 and 6.18. 104° in Idyllwild and

112° in Apple Valley on 6.16. 107° in

San Jacinto and 97° in Yorba Linda on

6.15.

9.4-8.2022

Very strong high pressure generated

high maximum temperature records

for September all over the West.

Several all-time high minimum

temperatures were set. On 9.4

Riverside’s min temp was 80°, and it

was 78° in Chula Vista and San Diego

(tie) for highest min temp on record.

Highest min temp records for

September: 92° in Palm Springs, 89°

in Borrego Springs, 83° in Anaheim,

82° in Burbank, 79° in San Jacinto. A

monsoonal heat wave drove temps

into the 90s at 7 am along the coast.

The heat wave was brought to an end

by remnants of tropical cyclone Kay.

The Fairview Fire erupted on the 9.5

southeast of Hemet. The heat primed

the dry fuels for rapid growth. It

would eventually burn 28,000 acres.

7.21.2023

A long heat wave enveloped the

region for most of the month. Palm

Springs hit 120° on this day. 18 days

this July recorded a high of 115° or

higher. Several low temperatures

remained in the 90s. July 2023 was the

hottest month on record for Palm

Springs, with an average temperature

of 98.5°.

In San Diego County, 224 heat-

related incidents were reported to

area hospitals.
