Punta Cana weather Oct 31 - Nov 9th?

What is the weather like this time of year in Punta Cana, specifically near Playas Uvero Alto (east side of island). I will be traveling the end of October into November with my wife & child. We are staying at a resort, but would like to explore outside of the resort.

Isla Catalina is highly recommended but is one hour and 30 minutes from the resort. Do you recommend a Taxi, bus, shuttle, or excursion?

What other things do you suggest? Thank you
