What You Should Know
It’s a Perfect Week for Outdoor Fun
With mostly warm, dry conditions all week, it’s the perfect time to go for a hike, a bike ride, or just relax outdoors. If you’ve been waiting for a good weather window to explore Camelback Mountain or South Mountain Park, now’s your chance!
Stay Hydrated as Temps Climb
Even though we’re not hitting the scorching summer heat yet, hydration is key. Keep a water bottle with you, especially if you’re outside during peak afternoon hours.
Don’t Forget the Sunscreen
The UV index is creeping up, and even spring sunshine can cause sunburn. If you’re spending time outside, lather up with sunscreen and throw on some sunglasses.
Cool Nights, So Keep a Light Jacket Handy
While the days are warm, evenings will still be a bit chilly, so bring a light sweater if you’re heading out after sunset.

Phoenix is moving toward full-on spring mode, which means warmer days and longer stretches of sunshine. If you’ve been waiting for that sweet spot between winter’s chill and summer’s scorching heat, this is it!
