Notes on Weather Data

For hikers in Connecticut and Massachusetts, one of the primary weather concerns is cold air temperatures and wind chills. While New England summers can be gorgeous, late fall and winter can get quite cold and hikers need to have proper data for planning their trips during these seasons. Additionally, hiking through mountain areas (like Mount Monadnock and along the Metacomet Ridge) can expose hikers to significant wind chill.

This NET page is our first opportunity to incorporate Wind Chill into the planner, which accounts for how the weather actually feels on exposed skin. This site uses the Steadman methodology for calculating apparent temperature, which both applies heat index when humidity is high and wind chill when temperatures are low with significant wind. vations in the Metacomet Ridge and Mount Tom Range.

In addition, we have added cold weather warnings to this planner whenever expected actual or apparent temperatures are expected to fall below 20 degrees Fahrenheit. This is a critical threshold for hikers, as most standard cold-weather camping gear (sleeping bags, insulating layers, shelters) is rated to around 20 degrees. Conditions at or below this level may push typical gear (such as puffy jackets and sleeping bags/quilts) to or beyond their limits, and extra care in gear selection and camp planning is warranted.

This is different than the formal Wind Chill Watches, Warnings, and Advisories issued by the National Weather Service at different levels. These thresholds may vary by region and time of year. In southern New England, a Wind Chill Warning is typically issued when wind chills are expected to reach −10 °F to −20 °F, and a Wind Chill Advisory at −5 °F to −10 °F — though local NWS offices may adjust these thresholds. Always check your local NWS forecast before heading out in cold conditions.
