MONTHLY WEATHER RECAPS...
JANUARY...RATHER MILD WEATHER FOR JANUARY FOR THE ASTORIA AREA.
WHILE SEVERAL FRONTS PUSHED ACROSS THE REGION, NOT MANY WERE ALL
THAT MUCH IN WAY OF RAIN PRODUCERS. AS SUCH, RAINFALL AT ASTORIA WAS
ONLY ABOUT 66% OF NORMAL. BUT, FRONT ON THE 9TH DID PACK SOME STRONG
WINDS, WITH GUSTS 50 TO 60 MPH ALONG THE COAST, KNOCKING DOWN TREE
LIMBS AND CREATING SPOTTY POWER OUTAGES. CLATSOP SPIT RECORDED A 71
MPH GUST.
FEBRUARY...IT WAS A COOL FEBRUARY, WITH TEMPERATURES MOSTLY IN THE
40S FOR HIGHS. COLDEST MORNING WAS THE 25TH, WITH A MORNING LOW
TEMPERATURE OF 23 DEG. CHILLY WET WEATHER ON THE 13TH AND 14TH, WITH
RAIN AT ASTORIA. BUT, SNOW FELL IN THE NEARBY MOUNTAINS, WITH 10
INCHES RECORDED ON SADDLE MOUNTAIN. COLD WEATHER RETURNED ON THE
22ND INTO THE 23RD, WITH A HIGH OF ONLY 35 DEG ON THE 23RD. EAST
WINDS GUSTING TO 35 MPH BROUGHT THE WIND CHILL DOWN TO NEAR 20 DEG
AT TIMES. BRRRRR! EVEN SNOW FELL DOWN AS LOW AS SEA LEVEL, WITH 1.5
INCHES OF SNOW AT ASTORIA, AND 3 INCHES AT NASELLE. MUCH HEAVIER
SNOW FELL IN THE COAST RANGE AND WILLAPA HILLS.
MARCH...COOLER THAN NORMAL, BUT NEAR NORMAL RAINFALL. MOST FRONTS
PUSHING ACROSS THE REGION BROUGHT GUSTY WINDS AND RAIN. STRONGEST
FRONT WAS ON THE 2ND INTO THE 3RD, WITH SOUTH WINDS GUSTING 50 TO 55
MPH ALONG WITH A 1.50 TO 2.00 INCHES OF RAIN. BUT, NO FLOODING. A
STRONG FRONT PUSHED ACROSS THE REGION ON THE 24TH AND 25TH. WHILE
ANOTHER 1 TO 2 INCHES OF RAIN FELL AT LOWER ELEVATIONS, IT WAS SNOW
FALLING IN THE NEARBY COAST RANGE, WITH OVER A FOOT OF SNOW.
APRIL...OVERALL, IT WAS A BIT WETTER AND COOLER THAN MOST APRILS.
FOR THE FIRST TIME SINCE DECEMBER, THERE WAS A DAY WITH OVER AN INCH
OF RAIN AT THE ASTORIA AIRPORT. IN FACT, APRIL HAD 3 SUCH DAYS, JUST
1 SHORT OF THE RECORD 4 DAYS BACK IN 1937. APRIL 2023 TOTAL
RAINFALL WAS 8.42 INCHES, MAKING IT THE 14TH WETTEST APRIL. BIT OF
OFFSHORE FLOW ON THE 28TH OF THE MONTH BROUGHT SUMMER WARMTH, WITH A
HIGH OF 86 DEG, BEFORE WINDS SWITCHED TO THE SOUTHWEST AND BROUGHT
COOLER OCEAN AIR BACK ONSHORE. THE HIGH OF 86 WAS THE WARMEST DAY
EVER IN THE MONTH OF APRIL, BREAKING THE OLD RECORD 85 SET IN 2016.
MAY...AFTER A RATHER DANKISH AND DAMP SPRING, MAY BROUGHT MUCH
DELIGHT TO AREA GARDENERS, WITH WARM AND DRIER WEATHER. WARMEST
STRETCH WAS AROUND MOTHERS DAY, WITH HIGHS INTO THE 80S ON THE 12TH
AND UP TO LOWER 90S ON 13TH. THE HIGH OF 93 DEG ON THE 13TH TIED
2008 (MAY 16) AS THE WARMEST TEMPERATURE RECORDED IN MAY. REST OF
MAY SAW DAILY HIGH TEMPERATURES MOSTLY IN THE 60S. RAINFALL WAS ONLY
34% OF NORMAL.
JUNE...JUNE CONTINUED WHERE MAY ENDED, WITH SEASONAL TEMPERATURES
AND DRY CONDITIONS. WARMEST DAY OF THE MONTH WAS ON THE 6TH, WITH A
HIGH OF 77 DEG. BUT, FIRST FRONT OF THE MONTH ARRIVED ON THE 9TH,
WITH SPOTTY LIGHT RAIN. STRONGEST FRONT OF MONTH BROUGHT CLOUDS,
RAIN AND COOL WEATHER FOR FATHERS DAY. REST OF JUNE WAS RATHER
UNEVENTFUL, WITH VARYING DEGREES OF ONSHORE FLOW.
JULY...RATHER PLEASANT JULY, WITH DAILY HIGHS MOSTLY IN THE UPPER
60S TO LOWER 70S. WARMEST DAY WAS THE 4TH OF JULY, WITH A HIGH OF 83
DEG. IN FACT, IT WAS THE 2ND WARMEST INDEPENDENCE DAY ON RECORD,
JUST ONE DEGREE SHY OF THE RECORD 84 DEG SET IN 1975.
AUGUST...WARM AND DRY, AS HIGH PRESSURE DOMINATED. WAS RELATIVELY
WARM AUGUST, WITH DAILY HIGHS MOSTLY IN THE 70S OR WARMER. WARMEST
WAS A 2-DAY STRETCH WITH HIGHS ABOVE 90 DEG ON 13TH AND 14TH, WITH
HIGHS PEAKING AT 95 DEG ON THE 14TH. IT WAS THE 3RD WARMEST AUGUST
ON RECORD FOR ASTORIA. MOST OF THE MONTH WAS DRY, WITH ONLY SPOTTY
LIGHT RAIN ON THE 9TH AND AGAIN ON THE 22ND. BUT THAT ALL CAME TO AN
END AS AUGUST CLOSED WITH RATHER STRONG FRONT. THAT FRONT BROUGHT
NEARLY A HALF INCH OF RAIN TO THE AREA, ALONG WITH COOLER WEATHER.
SEPTEMBER...ACTIVE WEATHER CONTINUED IN EARLY SEPTEMBER. HIGHS IN
THE UPPER 70S ON THE 1ST AND 2ND, ALONG WITH AN UNSTABLE AIR MASS,
TRIGGERED SHOWERS AND THUNDERSTORMS THROUGH THE 3RD. NO SEVERE
WEATHER, BUT DECENT DOWNPOURS AND GUSTY WINDS WITH A FEW STORMS.
AFTERWARDS, WEATHER BECAME TRANQUIL, WITH VARYING DEGREES OF ONSHORE
FLOW AND TEMPERATURES IN THE 60S TO LOWER 70S. BUT, RETURN TO MORE
ACTIVE WEATHER ARRIVED ON 18TH/19TH, WITH A FRONT MOVING ONSHORE. AN
EVEN STRONGER FRONT ARRIVED ON THE 23RD, WITH HEAVY RAIN. RAIN AND
SHOWERS, ALONG WITH COOLER TEMPERATURES, CONTINUED THROUGH THE 28TH.
GUSTY WINDS OF 55 TO 70 MPH ON THE 27TH CAUSED MINOR TREE DAMAGE AND
SPOTTY POWER OUTAGES.
OCTOBER...THE MONTH STARTED ON A WARMER THAN NORMAL NOTE, WITH HIGHS
PEAKING IN THE LOWER 80S ON THE 6TH. AFTER THAT, OCCASIONAL FRONTS
BROUGHT RAIN AND GRADUALLY COOLER TEMPERATURES TO THE REGION. HIGH
PRESSURE AT END OF THE MONTH BROUGHT LIGHT OFFSHORE FLOW, WITH DRY
WEATHER AND MILD DAYS, ALONG WITH COOL NIGHTS.
NOVEMBER...RATHER TYPICAL NOVEMBER, WITH NEAR NORMAL TEMPERATURES
AND RAINFALL. RATHER POTENT FRONT MOVED ONSHORE ON THE 2ND/3RD, WITH
WINDS GUSTING 45 TO 55 MPH AND HEAVY RAIN. ANOTHER POTENT FRONT
PUSHED ONSHORE ON THE 11TH, WITH GUSTY WINDS TO 50 MPH AND 2 TO 3
INCHES OF RAIN. THERE WAS SOME LOCALLIZED LOWLAND FLOODING, MAINLY
IN AREAS WITH POOR DRAINAGE. HIGH PRESSURE WAS STRONG ENOUGH FOR A
TIME TO BRING DRY WEATHER TO THE REGION FROM 23RD TO 28TH, MAKING
FOR A RATHER PLEASANT THANKSGIVING BREAK.
DECEMBER...RAIN RETURNED WITH A VENGEANCE TO START THE MONTH. A
SERIES OF ATMOSPHERIC RIVERS BROUGHT HEAVY RAIN AND GUSTY WINDS
DURING THE FIRST WEEK OF DECEMBER, WITH OVER 12 INCHES OF RAIN
AT ASTORIA AIRPORT AND OVER 20 INCHES IN THE NEARBY MOUNTAINS.
REST OF THE MONTH RETURNED TO MORE QUIET WEATHER, WITH ONLY A FEW
FRONTS WITH RAIN AT TIMES. PERSISTENT LOW PRESSURE OFFSHORE AT
END OF THE MONTH KICKED UP LARGE SWELL, RESULTING IN HEAVY SURF
CONDITIONS WITH SEAS OF 20 TO 25 FT ALONG THE COAST.
