Today is slightly warmer than average for October. The forecast high of 32°F is 3.1°F above the 29°F typical for this month.

Gusts to 50 mph will push high-sided vehicles on exposed roads and bridges. Overnight lows near 29°F mean ice is possible on bridges before dawn.
Above 60 degrees latitude, daylight swings enormously - summer nights barely darken and winter days are short.
Southern Hemisphere, so peak summer falls in December to February.
The gap between the warmest and coldest month averages 42°F - an unusually even climate through the year.
What to pack, what to skip
- A warm mid-layer and gloves for early mornings and evenings
- Insulated outer layer, hat and boots with grip for ice
- A packable rain shell - 2 of the next 7 days carry a real chance of rain
- Avoid high-elevation trails without traction devices - frozen surfaces persist in shade all day.
- Avoid exposed ridgelines, small boats and rooftop viewpoints while gusts stay above 50 mph.
- Avoid swimming outside patrolled areas - waves are running at 2.6 m.
- If your dates are flexible, avoid April, July and August - historically the least comfortable months here.
