Weather Tips for Deception Pass State Park
- Check marine wind, fog, tides, current, surf, or ferry conditions as appropriate; the inland temperature alone is not enough.
- Cold water, waves, current, wind, and lightning should guide water plans more than sunshine alone.
- Check overnight lows, wet ground, fire rules, drainage, and the nearest substantial shelter before settling into camp.
- Summer smoke, winter access, shoulder-season closures, and shorter fall daylight can matter even during an otherwise mild forecast.
