DAILY RECORDS

You'll find the most comprehensive, friendly and easy-to-use source of monthly weather averages on Weatherbase, guaranteed. But we know some of you are looking for daily records. Based on our research, we've found two great places to go to find that information.

The Weather Underground
This excellent site is old-school Internet, dating back to the early 1990s. Search for a forecast, and at the bottom of every forecast page, you'll find a drop-down menu that lets you check the daily minimum, maximum and average temperature, along with the conditions of the day. The records go from 1994 and current to within 24 hours. Records are both domestic and global. This is the place for recent historical data.

Utah Climate Center
The granddaddy of daily historical weather data. The Utah Climate Center has daily records for at least 5,000 locations (we lost count) spanning the globe, with some records dating back to the 19th century. If it's not on this site, it's not on the Internet. Data is current, usually to within six months, so we'd recommend it for data dating before the early 1990s. One important note: this site is not user-friendly, so be patient in wading through the data. It can be tough to use, but once you get the hang of it, it is all at your fingertips.


FORECAST SITES

Accuweather
These guys have been in the business longer than any of the other players, and generate their own forecasts. You can find 43,000 unique forecasts for the United States, with an option to buy more detailed weather forecasts, such as hour-by-hour forecasts.

Intellicast
This site is operated by WSI (owned by The Weather Channel. They do generate their own forecasts, but have limited global coverage. What they do well is "lifestyle" forecasts, giving you forecasts for ski conditions, gardening, boating, golfing, etc.

The Weather Channel
The Weather Channel does their own forecasts, and they do them quite well, despite leaning heavily on the National Weather Service. They have a good emphasis internationally. Their doppler radar maps are the most current, updating as frequently as every five minutes. One of our favorites, and a gold standard in terms of reliability.

Weatherbug
The weather nerds. Nice forecasting model, plus you can feed your own weather information back into their network, if you're so inclined.
