Month-by-Month Guide
January
The data shows impossibly high temperatures for Boise in January. Actual January weather in Boise features cold winter conditions with frequent freezing temperatures, occasional snow, and overcast skies. This is typically the coldest month of the year.
February
The provided data is not realistic for Boise. February typically remains cold with winter conditions persisting, though temperatures begin a gradual warming trend. Snow is still common, and days remain short.
March
The extreme temperatures shown are impossible. March in Boise actually marks the transition from winter to spring, with increasing daylight, occasional rain and snow, and gradually warming temperatures.
April
These temperatures would be fatal and are not accurate. Real April weather brings spring conditions with blooming flowers, mild temperatures, and a mix of sunny and rainy days as the region fully transitions from winter.
May
The data contains critical errors. May typically offers pleasant late spring weather in Boise with comfortable temperatures, longer days, and occasional rainfall, making it ideal for outdoor activities.
June
These impossible temperatures do not reflect reality. June normally brings the start of summer with warm, dry weather, long sunny days, and comfortable conditions for exploring the outdoors.
July
The data shows temperatures incompatible with life. July is actually Boise's warmest month with hot but manageable temperatures (typically around 90°F/32°C), very low rainfall, and abundant sunshine.
August
These extreme readings are erroneous. August continues summer's warm, dry pattern with hot days, cool nights, clear skies, and minimal precipitation, though temperatures begin moderating toward month's end.
September
The provided data is incorrect. September brings early autumn with decreasing temperatures, still-pleasant weather, and generally dry conditions ideal for outdoor activities and festivals.
October
These temperatures are impossible. October features classic fall weather with cooling temperatures, changing foliage colors, crisp air, and occasional rain as winter approaches.
November
The data does not reflect reality. November marks late autumn with significantly cooler temperatures, shorter days, increasing chances of frost and occasional early snow.
December
These readings are erroneous. December brings winter conditions with cold temperatures, short days, occasional snow, and holiday festivities, marking one of the coldest and quietest months for tourism.
