Temperature of 80.6°F recorded at Des Moines (KDSM) on June 1, 2026 at 16:15 UTC
Dew point of 64.4°F recorded at Des Moines (KDSM) on June 1, 2026 at 16:15 UTC
Wind speed of about 4.6 mph recorded at Des Moines (KDSM) on June 1, 2026 at 16:15 UTC

What changed
This is a point-in-time reading, not a trend — but the numbers paint a picture of a warm, moderately sticky early-June day in central Iowa:
- Temperature: 80.6°F
- Dew point: 64.4°F
- Wind speed: about 4.6 mph
- Barometric pressure: roughly 30.03 inHg
A dew point in the mid-60s means noticeable humidity but not the oppressive, tropical feel that comes when dew points climb into the 70s. Pressure near 30.03 inHg is close to the long-term average and suggests relatively settled weather at observation time.
Why it matters
Early June is a key window for Iowa corn emergence and early soybean vegetative growth. Warm daytime temps in the low 80s paired with moderate humidity generally support active crop development. The light wind and stable pressure suggest no strong frontal activity was passing through at observation time — though conditions can shift quickly this time of year.
Keep in mind this is a single station in Des Moines. Conditions across Iowa's 99 counties vary, especially with localized rain and terrain differences.
What to watch next
- Overnight lows and soil temps: How warm nights stay will influence growing degree day accumulation through the week.
- Rainfall forecasts: Whether moisture follows this humidity, or whether fields stay dry, could affect stands and early-season weed pressure.
- Dew point trends: If dew points keep climbing through the week, storm potential may rise.
