Alamo Lake State Park has two seasons: Hot and cold.
From June until September the temps can go from 100° to 118° in the day with lows in the upper 90s. It's usually over 100°. This is the time to bring sun block and shade. Some years are pleasant and we do not see the 100° mark until June; and other years we've seen it hit 100-plus in May. Although this is also monsoon season in Arizona we do not see much rain at the park. Humidity yes, rain no.
October through November bring more pleasant temperatures with highs in the 80s and lows in the 50s. From December until April you can count on 60° to 70° days with lows in the 30s and even 20s. Always be prepared with extra clothing.
