Climate Chart of Springfield, USA

Climate overview

Temperature

Monthly mean temperatures reach their lowest point in January, at -1.7 °C, and their highest in July, at 24.4 °C. These are averages for each month, not daytime maximum temperatures, so they describe the broad monthly pattern rather than the warmth of any particular afternoon. The unweighted mean of the monthly temperature means is 12.2 °C. It provides a compact overview across the calendar months, but is not a day-weighted annual average and cannot describe the temperature on a specific travel date.

Rain

Mean daily rainfall is highest in May, at 3.83 mm/day, and lowest in January, at 1.34 mm/day. These are daily means within the named months, not monthly rainfall totals; the lower figure does not guarantee rain-free days or indicate how often rain occurs. Across the calendar months, the unweighted mean of the monthly daily-rainfall means is 2.66 mm/day. It offers a broad reference point, rather than a prediction for a particular day or a measure of monthly accumulation.

Sunshine

Mean daily sunshine reaches its highest level in June, at 11.77 hours/day, while January / December has the lowest monthly mean, at 5.34 hours/day. The tied low applies to both listed months. These figures describe average sunshine duration per day, not daylight length or the sunshine visitors are assured of on any given day. The unweighted mean of the monthly daily-sunshine means is 8.42 hours/day. It summarizes the calendar-month averages without accounting for the different number of days in each month.

Snow

The highest monthly mean daily snowfall occurs in February, at 6.11 mm/day. This is a mean daily amount, not a monthly total, and does not establish how many days had snow, how deep it became, whether snow cover persisted or what conditions might be for skiing. The unweighted mean across the monthly daily-snowfall means is 1.29 mm/day. This broad average does not describe snowfall on an individual date or indicate the presence of snow cover.
