Today is about average for October. The forecast high of 69°F is in line with the 71°F typical for this month.
A 100% chance means rain is expected over most of the area. Plan indoor alternatives. Around 0,5 in is forecast, which is enough to soak trails and slow traffic.
Visibility is down to 1,2 mi - use low beams and leave extra following distance. Gusts to 34 mph will push high-sided vehicles on exposed roads and bridges. Wet roads are likely; braking distances roughly double in heavy rain.
Northern Hemisphere, so peak summer falls in June to August.
The gap between the warmest and coldest month averages 80°F.
What to pack, what to skip
- Layers - the daily swing is 64°F, so mornings feel nothing like afternoons
- A warm mid-layer and gloves for early mornings and evenings
- A packable rain shell - 3 of the next 7 days carry a real chance of rain
- Avoid exposed ridgelines, small boats and rooftop viewpoints while gusts stay above 34 mph.
- If your dates are flexible, avoid January, February and August - historically the least comfortable months here.
