Today is about average for August. The forecast high of 85°F is in line with the 86°F typical for this month.
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.
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 47°F.
What to pack, what to skip
- Lightweight, light-coloured clothing and a refillable water bottle
- Sunglasses, a brimmed hat and SPF 30+
- A packable rain shell - 7 of the next 7 days carry a real chance of rain
- Insect repellent and quick-dry fabrics for humidity
- If your dates are flexible, avoid May, June and September - historically the least comfortable months here.
