What June is like

June brings the longest days of the year — over fifteen hours of daylight — and the most rain, much of it in evening thunderstorms. Lupine blooms on the savanna, fireflies come out on warm nights and the village’s Firemen’s Street Dance usually lands on the third Saturday. Water levels are dropping toward their summer lows, opening the first sandbars.

In June, Marine on St. Croix averages a high of 77°F and a low of 60°F. It is the wettest. Expect about 4.5 in of rain spread over roughly 12 wet days. On average 4 days reach 85°F or warmer. Days last about 15.6 hours, with roughly 11.6 hours of sunshine.

The river in June

Long-term average flow at St. Croix Falls in June is 5,808 cfs — 29% above the yearly average. Expect a brisk current and cool water.

Best things to do in June

Based on climate normals and when wildlife is most often recorded, June is a good month for: paddling the st. croix, hiking, wildflowers, birding, butterflies & dragonflies.

  • Paddle a short float when flows are back near normal.
  • Watch fireflies over the park’s fields on a warm evening.
  • Dance on Judd Street at the Firemen’s Street Dance.

What to pack

  • breathable clothing
  • sun hat and sunscreen
  • plenty of water
  • insect repellent (ticks and mosquitoes are common in woods and wetlands)
  • a dry bag if you plan to paddle
