Is it too cold to swim in the Great Lakes? When you can dip your toes in the water
Warm weather doesn't always mean warm lakes, and while summer in Michigan is approaching, residents planning their next trip to the one of the Great Lakes should wait a little longer before jumping in.
Water temperature throughout the Great Lakes currently do not exceed 68 degrees Fahrenheit. The warmest water temperature in the Great Lakes Monday, May 19, is 63.5 degrees Fahrenheit near Bay City, and the surface temperature is 41.9 degrees near Toronto, according to Seatemperature.com.
Lake Superior, the largest of the lakes, had its highest reading at 52.5 degrees Fahrenheit near Sault Ste. Marie, Seatemperature.com said as of May 19. Lake Superior was barely above freezing at 36.3 degrees near Grand Portage, Minnesota.
Lake Michigan was the second-coldest of the five Great Lakes with an average of 51.1 degrees. Lake Ontario posted a high reading of 54.3 degrees, and Lake Huron's high was 63.5 degrees in Saginaw Bay.
Lake Erie, the shallowest of the lakes, was the warmest at 64.6 degrees near Monroe.
Swimming is most comfortable in lake waters at about 70 degrees, according to Swimoutlet.com.
With lake temperatures rising, but not expected to peak until late summer/early fall, according to GLISA, the best thing to do to avoid hypothermia and panic is wait to swim.
Here's what you should know about when it's time to swim in the Great Lakes:

In June, the warmest average water temperature Great Lakes is 70.5 degrees, near Bay City, and the coldest temperature is 47.3 degrees, near Duluth.
Temperatures climb in the spring and summer months, reaching peak temperatures in the late summer and early fall, according to GLISA, a collaborative between Michigan State University, University of Michigan and by the National Oceanic and Atmospheric Administration.
Lake Michigan was the second-coldest of the five Great Lakes at 51.1 degrees, according to Seatemperature.com as of May 19.
The warmest water temperature in Lake Michigan was 62.6 degrees (Green Bay, Wisconsin), and the coldest temperature is 39.6 degrees (Fairport, Michigan).
Lake Michigan reaches an average of 70.5 degrees Fahrenheit in August.

Prolonged exposure could result in loss of muscle control in your arms,legs, hands and feet, triggering hypothermia among other things that can be fatal.
The first day of summer is marked by the summer solstice, which can be either June 20 or 21, occurring when the Earth tilts toward the sun is at a maximum, reporting from the Detroit Free Press shows.
This year's is on June 20, although summer temperatures may start earlier.

Fast-moving brush fire on Hawaii's Maui island evacuates about 50 people. No structures have burned
HONOLULU (AP) — A fast-moving Hawaii brush fire fueled by fierce winds forced the evacuation of about 50 Maui residents on the opposite side of the same island where a devastating blaze killed over 100 people two years ago. The fire started Sunday in a sparsely populated area with land set aside for Native Hawaiians. Fire size now estimated at 330 acres The Kahikinui was initially estimated at 500 acres (202 hectares), but aerial surveys overnight put the estimate at about 330 acres (134 hectares), Maui's fire department said. The fire is 80% contained. The remote, challenging terrain made it difficult to estimate the fire's size, the department said in a statement. A police drone showed hot spots, but none flared overnight. No injuries or structural damage was reported. Weather conditions were mostly sunny Monday with a high of 67 degrees Fahrenheit (19 degrees Celsius) and east winds of about 15 mph (24 kph), gusting up to about 25 mph (40 kph). Authorities conducted door-to-door evacuations and part of a highway remains closed. Flashbacks to an earlier fire Warren Aganos was on his family's Hawaiian Homelands lot preparing to go on a Father's Day hunt when a neighbor called him around 9 a.m. telling him a fire had broken out. 'I hung up and raced out, I didn't let her finish,' said Aganos, who has been slowly rebuilding the three structures his family lost in a 2016 brush fire that burned over 5,000 acres (2,000 hectares) in the same area. 'I was thinking about the last one,' he said. 'It was super emotional.' Aganos said he rushed in his truck to make sure first responders knew where the community's water storage tanks were before navigating Kahikinui's dirt roads down to the highway where he could see smoke billowing over the hillside. The community lacks electrical and water infrastructure, and some of the roads are only navigable by four-wheel drive. What is the region like? Kahikinui is less populated and developed than Lahaina, which was the Hawaiian Kingdom's capital in the 1800s and is now a popular tourist destination. Kahikinui was used for cattle ranching for many years and is near a state forest reserve. The fire department sent engines, tankers and a helicopter to battle the blaze. Three bulldozers cut firebreaks in the lower part of the community, Desiree Graham, co-chair of Kahikinui's firewise committee, said. The area has 104 Hawaiian homeland lots of 10 to 20 acres (4 to 8 hectares) each. About 40 lots have homes, including 15 with full-time residents. Some lots have more than one home, Graham said. A state agency issues lot leases under a program Congress created in 1920 to help Native Hawaiians become economically self-sufficient. Those with at least 50% Hawaiian blood quantum can apply for a 99-year lease for $1 a year. Fire devastated Lahaina nearly two years ago Maui is still recovering from the massive inferno that enveloped Lahaina in August 2023. That fire was the deadliest in the U.S. in more than a century. It destroyed thousands of properties and caused an estimated $5.5 billion in damage. University of Hawaii researchers say unemployment and poverty rose after the blaze. The Kahikinui fire may seem small compared to continental U.S. fires, but it's significant for an island of 735 square miles (1,903 square kilometers). Other Western fires Crews also are battling wildfires in the Pacific Northwest, around the Great Basin, in California and the Rockies. National Weather Service forecasters and federal land managers have warned in recent weeks that fire danger is escalating in many places amid rising daytime temperatures and single-digit humidity levels. The risks won't start to wane — at least in the southwestern U.S. — until the monsoon starts to kick in, bringing much-needed rain. In southern New Mexico, a wildfire ballooned to nearly 30 square miles (77 square kilometers) over the weekend in the Gila National Forest. The flames forced the evacuations of homes that dot the mountains north of Silver City, blocked access to the Gila Cliff Dwellings National Monument and prompted air quality warnings as smoke drifted north. Campgrounds and access points to the Continental Divide National Scenic Trail also were closed. In Oregon, several dozen homes in Wasco County were destroyed by a fire that started last Wednesday. Some evacuations remained, but fire managers said Monday that the threat to structures had diminished. So far this year, the nation has seen double the number of fires as last year but the acreage is less, according to the National Interagency Fire Center. More than 2,700 wildland firefighters and support personnel were assigned to 15 large wildfires across the country. —- ___

Tropical depression could form in Pacific in next few days: See tracker, spaghetti models
Tropical depression could form in Pacific in next few days: See tracker, spaghetti models Show Caption Hide Caption How to prepare for a hurricane It's important to take these steps before hurricane season. Another tropical storm could soon form in the Pacific Ocean. The National Hurricane Center said early Monday morning a broad area of low pressure "continues to produce disorganized showers and thunderstorms" over and offshore of Central America. Hurricane center forecasters said environmental conditions appear conducive for "gradual development" of this system, currently labeled as EP94, and that a tropical depression is likely to form "in the next day or two" as the system moves west-northwestward near the coasts of El Salvador, Guatemala and southeastern Mexico. The NHC said interests in these locations should monitor the progress of this system and that, regardless of development, areas of heavy rain are likely across portions of Central America and southeastern Mexico during the next few days. The hurricane center gives the system a 80% chance of formation through the next 48 hours and an 90% chance of formation through the next seven days. Pacific storm tracker This forecast track shows the most likely path of the center of the storm. It does not illustrate the full width of the storm or its impacts, and the center of the storm is likely to travel outside the cone up to 33% of the time. EP94 spaghetti models Illustrations include an array of forecast tools and models, and not all are created equal. The hurricane center uses only the top four or five highest-performing models to help make its forecasts. How do hurricanes form? Hurricanes are born in the tropics, above warm water. Clusters of thunderstorms can develop over the ocean when water temperatures exceed 80 degrees Fahrenheit. If conditions are right, the clusters swirl into a storm known as a tropical wave or tropical depression. A tropical depression becomes a named tropical storm once its sustained wind speeds reaches 39 miles per hour. When its winds reach 74 mph, the storm officially becomes a hurricane. Prepare now for hurricanes Delaying potentially life-saving preparations could mean waiting until it's too late. "Get your disaster supplies while the shelves are still stocked, and get that insurance checkup early, as flood insurance requires a 30-day waiting period," NOAA recommends.

Grand Canyon Hikers Told To Avoid All Physical Activity
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The National Weather Service (NWS) has issued an extreme heat warning on Monday for parts of Arizona including the Grand Canyon, warning that prolonged outdoor exposure presents health risks due to "dangerously hot conditions." Why It Matters The NWS says that extreme heat warnings are "reserved for only the hottest days of the year," and are "issued when temperatures are expected to rise to dangerous levels." Officials cautioned that without proper cooling and hydration, individuals face a risk of heat-related illnesses, particularly with extended exposure outdoors. The entrance to the Grand Canyon National Park pictured in February. The entrance to the Grand Canyon National Park pictured in To Know The NWS alert warns of "dangerously hot conditions" below 4,000 feet in the Grand Canyon on Monday, with daytime temperatures ranging from 102 degrees Fahrenheit at Havasupai Gardens, to 114 degrees at Phantom Ranch. "Day hikers on Bright Angel Trail should descend no farther than 1 1/2 miles from the upper trailhead," the NWS said. "Between the hours of 10 a.m. and 4 p.m., hikers should be out of the canyon or at Havasupai Gardens or Bright Angel campgrounds, physical activity is discouraged." It said that hikers should carry proper gear such as a wide-brimmed hat, sunscreen, salty snacks, enough water, and an electrolyte mix. It added that increasing calorie intake can help sustain energy levels. The extreme heat warnings also cover southern Arizona more widely, as well as a neighboring portion of southeastern California, with temperatures up to 116 degrees possible in places. Elsewhere, heat advisories have been issued for parts of New Mexico and western Texas, where triple-digit temperatures are expected on Monday.

Ty ONeil/AP What People Are Saying The NWS forecast office in Flagstaff, Arizona, said on X, formerly Twitter, on Saturday: "An Extreme Heat Warning remains in effect through Monday for the Grand Canyon below 4000'. Be sure to exercise enhanced caution with any outdoor activities, especially for individuals who are sensitive to heat." The NWS said on X on Wednesday: "During hot and humid weather, your body's ability to cool itself is challenged in ways you may not expect. When your body heats too rapidly, or when too much fluid or salt is lost through dehydration or sweating, you may experience a heat-related illness. Stay weather-ready by learning the symptoms of extreme heat exposure and the appropriate responses." NWS Phoenix said on X on Sunday:"High temperatures will be running 5-10 degrees above normal this week, with the hottest day being today. Temperatures will also be similarly hot on Thursday for south-central and southeastern AZ, following the passage of a dry and weak weather system early week." What Happens Next The extreme heat warning for southern parts of Arizona is set to remain in force until 8 p.m. on Monday evening. The NWS issues regular forecast updates on its website and social media channels.
