1st April..

With March over now, we have the real feel of an Indian Summer starting..

March was near normal in 2024...and compare with 2022 , as shown below.

                                                                         👇March 2024 

March 2022 👇

Now, in most parts of India, in April and May, we can normally expect  the temperatures in the day to rise to 41-46c. That will be the shade temperatures as recorded, and the "real Feel" can go even higher !...
Also, if exposed to the afternoon sun, direct sun temperatures can reach 60c !

This is to be Alert, and not Panic.

Some do's and don'ts..

Older adults do not adjust as well as young people to sudden changes in temperature.

**What is Heat Stroke ?

Heat stroke is the most serious heat-related illness. 

*It occurs when the body becomes unable to control its temperature: the body’s temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. 

*The body normally cools itself by sweating. But under some conditions, sweating just isn’t enough. In such cases, a person’s body temperature rises rapidly. 

*When the humidity is high (>65-70%), sweat will not evaporate as quickly, preventing the body from releasing heat quickly. 

*Body temperature may rise to 106°F or higher within 10 to 15 minutes. 

*Heat stroke can cause death or permanent disability if emergency treatment is not provided.

**Precautionary care: 

Avoid alcohol, hot tea, hot coffee and carbonated soft drinks, which dehydrates the body. 

Avoid high-protein food and do not eat stale food. 

If you work outside, use a hat or an umbrella and also use a damp cloth on your head, neck, face and limbs. 

**Never leave kids in a parked car

*Even when it feels cool outside, cars can heat up to dangerous temperatures very quickly.

*Leaving a window open is not enough- temperatures inside the car can rise almost 60c-70c within the first 20 minutes, even with a window cracked open.

*Children who are left unattended in parked cars are at greatest risk for heat stroke.

*Stay hydrated: during days of extreme heat, keep drinking water, especially if outdoors or performing physical activity.

**Tips for Preventing Heat-Related Illness

*Wear Appropriate Clothing: Choose lightweight, loose-fitting clothing.

*Stay Cool Indoors: Stay in an air cooled/air-conditioned place as much as possible. ...

**Schedule Outdoor Activities Carefully: 

*Try to limit your outdoor activity to when it's coolest, like morning and evening hours.

The latest Climate Driver Update and Climate Model Summary are now available on our website.

El Niño near its end

El Niño continues and is near its end. Climate models indicate sea surface temperatures in the central tropical Pacific are expected to return to ENSO-neutral later in autumn 2024.
Oceanic indicators such as tropical Pacific sea surface temperatures are still meeting El Niño thresholds and atmospheric indicators are consistent with a decaying El Niño.

International climate models suggest the central tropical Pacific Ocean is likely to return to neutral El Niño–Southern Oscillation (ENSO) levels by the end of April (i.e., neither El Niño nor La Niña), and all models indicating neutral in May.

While four out of seven international models are predicting a La Niña by late winter, the forecasts of the ENSO state beyond May should be used with caution. ENSO forecasts have historically had their lowest skill for forecasts issued in April, with skill increasing from May.

The oceans have been the warmest on record globally since April 2023. The global pattern of warmth is affecting the typical historical global pattern of sea surface temperatures associated with ENSO variability. As the current global ocean conditions have not been observed before, inferences of how ENSO may develop in 2024 that are based on past events may not be reliable.

The Indian Ocean Dipole (IOD) index is neutral. Although the most recent value of IOD (+0.95 °C) is above the positive IOD threshold, sustained values of the IOD index above the threshold are required for an IOD event to form. The eastern Indian Ocean has cooled in recent weeks, due to increased monsoonal activity in the area, including tropical low 08U, which developed into Severe Tropical Cyclone Nathan.

The Southern Annular Mode (SAM) is currently positive, as of 2 April. Forecasts indicate SAM will remain positive for almost a week before it returns to neutral.
The Madden–Julian Oscillation (MJO) has moved into the western Indian Ocean and has weakened. Most climate models surveyed indicate that the weak MJO will likely move eastward across the Indian Ocean and the Maritime Continent the coming week and into the Western Pacific by mid-April.

Read the full report on our website. It includes the latest updates on climate drivers in the Pacific, Indian and Southern oceans, and the tropics.
