In other Luzon areas, warm temperatures will also be experienced this Sunday.

Maximum temperature will reach 37 °C in Tuguegarao; 33 °C in Kalayaan Islands and 33 °C in Puerto Princesa.

Elsewhere, maximum temperature in Tagaytay is expected to reach 32 °C while Legazpi will record a maximum temperature of 32 °C.

According to a 4 a.m. weather update, PAGASA said the whole of Luzon will experience hot weather, especially on Sunday afternoon.

In a post, PAGASA defines heat index as "human discomfort index" that provides apparent temperature or what humans feel as the temperature affects their body.

A heat index ranging from 41 °C to 54 °C could lead to heat cramps and heat exhaustion. For areas with temperatures of 32 °C  to 41 °C, heat cramps and heat exhaustion are possible.

PAGASA advised the public to follow these tips during hot weather conditions:

• Stay indoors as much as possible, if air conditioning is not available, stay on the lowest floor out of the sunshine
• Wear lightweight and light colored clothing. Light colors will reflect the sun's energy.
• Drink plenty of water regularly. The body needs water to keep cool.
• Water is the safest liquid to drink during heat emergencies. Avoid drinking liquor because it dehydrates the body.
• Eat small meals however eat more often. Avoid eating foods high in protein which can increase metabolic heat.
