With El Niño strengthening, experts say a 30-day head start is enough to make a real difference at home and in your budget. Start with the basics: make sure your emergency kits are up to date and your household has a basic family preparedness plan. Next, look for easy home projects that pay off during temperature swings and higher energy bills. Experts suggest building slack into your monthly budget and leaning on local produce as El Niño impacts global crops.
