A 100% chance means rain is expected over most of the area. Plan indoor alternatives. Around 0,6 in is forecast, which is enough to soak trails and slow traffic.
Visibility is down to 0,2 mi - use low beams and leave extra following distance. Gusts to 64 mph will push high-sided vehicles on exposed roads and bridges. Overnight lows near 5°F mean ice is possible on bridges before dawn. Wet roads are likely; braking distances roughly double in heavy rain.
Southern Hemisphere, so peak summer falls in December to February.
The gap between the warmest and coldest month averages 48°F.
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 - 7 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 64 mph.
- Avoid swimming outside patrolled areas - waves are running at 2.9 m.
- If your dates are flexible, avoid May, June and July - historically the least comfortable months here.
