Marine Weather and Tide Forecast for Gardiner, OR

AVIATION
15/18Z TAFs...VFR prevails most areas late this morning.
Satellite imagery is showing some broken ceilings at or around 5000 feet over Coos and Douglas counties. Expect gusty winds (20-30 kt)
this afternoon with increasing high clouds.

Another disturbance with a deep marine push will move in tonight.
This will cause areas of light rain/drizzle along the coast and over to the Cascades along with a mix of VFR/MVFR ceilings. Some higher terrain will become obscured. Most precip will fizzle south of the Rogue-Umpqua Divide, but there could be a little light rain or drizzle up against the terrain of the Siskiyous due to the increased depth of the marine layer. With snow levels dropping to around 4000 feet by Saturday morning, some light snow may mix in as well down to that elevation. Onshore flow will keep a mix of VFR/MVFR ceilings near and west/north of the Cascades/Siskiyous into Saturday afternoon with mainly VFR south of there. With low pressure sliding southward over the area Saturday night into Sunday morning, some cloud cover and light precip will linger, primarily around the mountains. -Spilde



MARINE
Updated 1050 AM PDT Friday, May 15, 2026...Gusty north to northwest winds and steep seas are expected for areas from Gold Beach southward through this evening. Steep seas expand northward to all areas by Saturday as an increasing swell builds into the waters. North winds will also strengthen late Saturday. Strongest winds and highest seas are expected from Gold Beach southward.
Multiple northwest swell trains will move through area waters into early next week with persistent gusty north winds. This will likely maintain steep seas for much of the area through mid next week. -Spilde

SHORT TERM...

KEY MESSAGES...

* Seasonable temperatures are expected today with breezy to gusty afternoons/evening winds.

* Disturbances moving through the region bringing cooler temperatures and bring enhanced west to northwest afternoon winds along with nightly marine pushes along the coast and into the Umpqua Basin through the weekend.

* Light rain possible along the coast and north of the Rogue- Umpqua Divide on Saturday.

* Localized frost is possible Saturday night and Sunday night in some west side valley, with highest chances in the the Illinois and Applegate valleys, and portions of the lower Klamath River Valley in western-central Siskiyou. Near and below freezing temperatures likely in the Scott and Shasta Valleys and east of the Cascades.

As a weak front moved inland, a marine push of lower to mid clouds has moved into areas from the Cascades west overnight.
These clouds are likely break up and clear this afternoon. East side areas and Northern California zones will remain mostly clear.
Afternoon temperatures are expected to be near normal with highs in the mid 60s to mid 70s across valleys and near 60 along the coast.

A weak trough will move into the region from the northwest tonight and Saturday. With this trough, expect chances for light rain along the coast and into the Umpqua Basin tonight and Saturday morning. The snow level Saturday morning is forecast to be around 4000 feet, so don't be surprised if there happen to be some wet snow flakes near and north of Union Creek Saturday morning.
Overall, precipitation is expected to be light. There is a slight chance (10-20%) for light precipitation south of the Rogue-Umpqua Divide in Jackson and Josephine counties. This system will also bring cooler temperatures with highs trending around 5-10 degrees below normal.

This trough will shift east late Saturday and deepen on Sunday just east of the area, across eastern Oregon, Idaho, northern Nevada and western Montana.

Breezy to gusty winds are likely both Saturday and Sunday afternoon/evening as this trough remains over the area or just to the east. Cooler temperatures remain in place on Sunday, trending slightly warmer on Monday. Nighttime lows Saturday night and Sunday night will trend lower. The National Blend of Models and current guidance supports temperatures in the 33-37 range with a chance for patchy frost in portions of the Illinois and Applegate valleys, as well as portions of the lower Klamath River in west- central the lower Klamath River Valley. Outlying areas in the Rogue Valley may also see temperatures briefly lower into the mid 30s during this period. We will continue to monitor this period and evaluate for the potential for a frost advisory.
Temperatures will be colder in the Scott and Shasta Valleys (lower 30s) and east of the Cascades (20s to low 30s).

LONG TERM...Upper level heights rise next week, so we expect a dry pattern along with a warming trend. Temperatures rise to around normal Monday, then back to above normal levels Tue-Thu.
We'll remain in WNW flow aloft during this time period with weak disturbances pushing by to the north every now and then. This means that while it will turn warmer, no huge heat waves are expected. Marine layer intrusions are likely to continue at the coast during the nights/mornings.

AVIATION (12Z TAFs)...

Lower to mid clouds have filled inland across southwest Oregon from the Cascades weest. This will bring area of MVFR ceilings this morning and mountain obscuration. Lower and mid clouds will gradually lift and clear in the afternoon. With conditions becoming VFR areawide. Breezy wind speeds are expected in the afternoon hours with increasing high clouds. Lastly, isolated showers will enter the region this evening which may result in MVFR ceilings. These conditions spread into the Umpqua Valley Friday night.
