The windiest month of the year in Omaha is April , with an average hourly wind speed of The calmer time of year lasts for 4. The calmest month of the year in Omaha is August , with an average hourly wind speed of 8.

The wind is most often from the south for 7. The wind is most often from the north for 5. To characterize how pleasant the weather is in Omaha throughout the year, we compute two travel scores. Based on this score, the best time of year to visit Omaha for general outdoor tourist activities is from early June to mid September , with a peak score in the last week of August. Based on this score, the best time of year to visit Omaha for hot-weather activities is from late June to mid August , with a peak score in the third week of July.

For each hour between AM and PM of each day in the analysis period to , independent scores are computed for perceived temperature, cloud cover, and total precipitation. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed.

Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies. Our precipitation score , which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0. The growing season in Omaha typically lasts for 6. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature.

Based on growing degree days alone, the first spring blooms in Omaha should appear around April 2 , only rarely appearing before March 20 or after April This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents.

Shortwave radiation includes visible light and ultraviolet radiation. The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year. The brighter period of the year lasts for 3. The brightest month of the year in Omaha is July , with an average of 7. The darker period of the year lasts for 3. The darkest month of the year in Omaha is December , with an average of 1. For the purposes of this report, the geographical coordinates of Omaha are The topography within 2 miles of Omaha contains only modest variations in elevation, with a maximum elevation change of feet and an average elevation above sea level of 1, feet.

Within 10 miles also contains only modest variations in elevation feet. Within 50 miles contains only modest variations in elevation feet. This report illustrates the typical weather in Omaha, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, to December 31, There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Omaha.

For each station, the records are corrected for the elevation difference between that station and Omaha according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The estimated value at Omaha is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Omaha and a given station. To get a sense of how much these sources agree with each other, you can view a comparison of Omaha and the stations that contribute to our estimates of its temperature history and climate. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.

All data relating to the Sun's position e. This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a kilometer grid.

Highs range from Rain is somewhat common with 3 to 8 days of significant precipitation per month. Spring is the second busiest for tourism, which makes it a good time for those looking for things to do.

The middle-year months have very comfortable weather with high temperatures that are quite warm. These months see the most precipitation with 5 to 8 days of precipitation per month.

June — August is the busiest season for tourism in Omaha, so lodging and other accommodations may cost more than usual. Fall daily highs range from It rains or snows a significant amount: 2 to 6 days per month.

Tourism is the slowest during these months due to the weather, so hotels may be affordably priced. Weather is far too cold this time of year in Omaha to be enjoyable for warm weather travelers.

The average high during this season is between On average, it rains or snows a smalll amount: 1 to 4 times per month.

These times of year are fairly slow with tourists. Other Omaha Travel Info. Omaha Temperatures Fahrenheit. Omaha Temperatures Celsius. Omaha Perceived Temperature F. Omaha Perceived Temperature C. I was wondering if it would be Lexington, Kearney, or North Platte or any other ideas of where. My guess is that is gradual and subtle as one goes along I Thinking of my trip to Colorado, this thought came to mind. I am curious to see what others think of the humidity transition from east to west in Nebraska.

I heard people say the th meridan is where the air gets dry, which would mean Cozad, Nebraska which is just west of Lexington.

Of course there is no defined line. North Platte is probably more humid than say Scottsbluff or Sidney. Irrigation season also contributes to the humidity in Nebraska, out west you have less irrigation than central and eastern Nebraska.

I have also heard people say the th meridan is where the west begins, and I have also heard where the prarie grass switches to sagebrush is where the west begins. Gretchen B. I've lived in Ogallala, North Platte, and Lexington.

Of the three, Lexington was definitely the most humid and Ogalalla was the driest. From about there east it's pretty humid. When you're in "wheat country" it's pretty dry, but once you're in "corn country" it's more humid.

Gretchen, that makes perfect sense. The perspiration of the corn contributes to the humidity and this is noticed in South Dakota. Areas with a lot of corn are generally more humid than those that are with wheat or rangeland.

Then again, corn is grown in areas where there is more water or easy access to water due to it being a crop that requires more water than other crops such as wheat. It seems like Lexington and on east appears green and lush and oftentimes has bugs. It seem like the car starts getting littered with bug guts when it head east on I east of Lexington West of there, it is generally not an issue. West of Lexington, it seems like the grass is browner and less trees along the Platte and less bugs.

It is interesting to see the subtle changes in Nebraska and other places when passing through. A lot of it too has to do with the southerlies It's interesting how you noted around GI as a point of transition, because west of GI it starts to demand a bit more of a SE directed wind than say east of GI where a straight south wind will bring up humidity.

In Scottsbluff, it takes quite a SE breeze to get its humidity up. If you remember a couple of other threads about rainfall varying quite a bit, and tornados in GI?
